If you have ANY GM with a 3800 3.8L V6 with the "Reduced Engine Power" message, and / or you are getting any of these codes p1125, p2125, p2138 DO NOT REPLACE PARTS until you watch this video! If this video helped you, hit that LIKE button and subscribe! Thanks!

Bought 3 $200 throttle body and 2 brand new gas pedals and still had the same problem...this video helps a lot....we need more GP videos...thanks yu really helped

Thanks, Randy. Just saved me a lot of grief and helped me get my '06 Grand Prix running again, after having it towed home yesterday (reduced engine power). It was two rodent chewed wires, right next to the harness you had problems with. Soldered them back together, and runs great again. Really appreciate the library of videos you've created over all these years.

Getting a throttle body And a pedal assembly is what the South Main Auto chnl calls " shooting the parts cannon " lol. Good job 👍

THANK YOU!!! YOU JUST SAVED ME HOURS OF TROUBLESHOOTING!!! I just replaced the radiator for a friends daughter and moved the air box out of the way to get it out . Started it and immediatly went into Reduced Power Mode. With TPS harness running to the to air box I knew there had to be a broken wire somewhere but Damn.... That's a lot of wires! Soon as I saw the wear on your valve cover, EUREKA! Thanks Again, It would have take me all night to trace. 🍻

appericate the video help me out perfectly today lifted harness , broken wires total of 5 thanks again keep up the good work

Just changed crank sensor twice trottlebody twice 02 sensor map sensor twice gas paddle assabley check fuel pressure twice changed plugs and wires watched this vidieo bingo most useful one I watched this year thanks

God's job Randy! These video will save a lot of money to someone in need!!!!

Amazing how a simple fix like that can be done to be ready to rock and roll. Thanks for the video. Btw Randy, I found you. Lol

My 2007 GP GT went into limp mode, reduced engine power/ service traction control. After watching this video, the throttle body or tps was not my first thought as to the culprit although I did clean the throttle body bore and replace the assembly with a known good assembly from my other GP and satisfied my curiosity when it didn't correct the problem. Checking the obvious such as chaffed or broken wires and finding none, a simple pinpoint test led me to the accelerator pedal which I replaced for 125.00 purchased from my local NAPA which corrected the problem. Now if someone can tell what is causing my battery to go dead anywhere from 3 days to 2 plus weeks. A three-year-old battery was replaced at 4 years as it tested bad, 17 days later the car needed a jump. Battery and alternator test good, charge rate at 14.3 to 14.6. 5 days later battery dead again, 2 shops can't find a draw. Have since installed a battery cutoff which is a pain in the ass to deal with.

Finally got around to checking out the second channel. Liking the content so far Hate that you started replacing parts before diagnosis but the education was well worth the money spent. And you now have a running car for less around 500 bucks. Now time to clean it, put it up for sale, and get back to copart for the next diamond in the rough

Thank you very much. I replaced the the throttle assembly and it didn’t help. I watched your video and that was exactly what was wrong. I had one broken wire and one bare wire. I repaired them and the erased the codes and seems to be fixed now. Thank you!

An old piece of hose would work. Keep some old radiator hoses around just for that reason.

Great work. A simple design oversight can cause a major problem. The solution was quite ingenious, as you used the correct material for a similar task.

Randy you should polish those headlights, use mothers aluminum polish it works soooo good and takes less than 10 minutes. No sanding the lights or anything it's so easy I could do it in my sleep and genuinely makes the headlights look new

This was so satisfying to watch good thinking bro some people would have never thought to check for wires

I don’t believe this was my problem but this helps a lot to give a good start on a very annoying code. Thanks!

I have 2006 and my motor you can eat off of that is way this wiring went out , so clean that motor and take care of your vehicles no matter what make it is and they will last , but good find well done 👍

Wow, great advice. I have a 2004 Buick LeSabre with the same 3.8 V6. Tomorrow I will check my car to make sure that doesn't happen to me. Keep up with the videos.

Glad to see things on this channel again. Awesome

Wow glad it was just those wires! Now she runs great!!

My 07 is having this problem....thanks for this video.....

Hey bro you ARE THE MAN!! You are a God send. I've been goin through hell trying to figure out what was wrong with my 07 lacrosse.. Although I ran across your video 1 day and $438 bucks to late.. I keep tape and wire on hand constantly.. I replaced the throttle body for nil.. and after doing just what you did I can say PROBLEM SOLVED.. THANK YOU.

Awesome work. Such an easy fix for a beautiful car. Love the channel.

I have the same car I’m glad to found this video... even when my car sit it still have that reduced engine power I’m going to look at my wires

Great catch Randy! At least you didn't spend a ton of money trying to fix this. Didn't know you had a second channel on KZfaq. Thanks for the heads up. Now subscribed here as well!

Mine 2006 gives me the reduced engine power every now and then. I checked that exact location, and it has that burn on the valve cover and exposed wires. Im betting that is it. Thanks!!!!!

One of your best vids Randy !! Should have been on the main Chanel it would have done well !! Well done

Awesome job Randy. I watch every video from the Bahamas. I'm wondering if you ever see my comments. Great content with regular cars that the average man may come across. P.s. no Carnage lol. Takes up time for fixable car showcases lol

I keep some old heater hose around just to wrap around wires from time to time.

Excellent diagnosing, Randy!!!

Nice find bro ! Always did like those grand prix's

You saved me so much time and money.. THANK YOU. SAME PROBLEM

That's awesome, Randy. I really hope I can do what you do in the future. It might be stressful to you, but you have a great job.

Big fan from PUERTO RICO 🇵🇷

Congrats on the easy fix. That car will clean up nicely.... Perfect timing with tax season in full swing

Glad to see it running good 300 dollar Pontiac for the win

Doing this now....saw this video while getting a price on a new throttle body - YIKES!!!! Hopefully I have the same fix.... digging in now...I'll report back 👍🧐

Nice fix, I miss having a 3.8, it’s such a good engine

Great diagnosis Randy! Nice protection idea. Did you soldier them?

Very good video a lot cars in them years had wiring problems

Do you believe that fixing the wires it helped with the evap code? I have a 2005 with the evap code.

Like I said lots of potential.Great job Randy .

Thank you, do you know where I can buy Conduit or wire protection. I don’t want to try it and then have exposed wiring

That was a very good fix man .iam inpressed randy

Not sure if this will be seen but I replaced throttle body and pedal as well as checked most of the wiring (what I can all get easy access to) and everything looks fine. So now I'm stuck and don't know where to go from here. I'm not sure if there is more wiring that I need to somehow get to that isn't as easy.

I love your videos Randy I always follow you up watching from Malawi

My car is flashing those codes. Sometimes only p1125 and p2138 and then sometimes also p2125 with those other two. Haven’t had it for long. Looked at harness and it looks like someone had already put a piece of hydraulic hose under wires in that spot. I need a continuity tester

Great job Randy!

Dude thank you so much! My harness has the same damn cut with the same dang exposed wires! Worst part is the issue started the second I bought it. Before I could get it home it died on me, then let me start the car(roughly). Dudes have been dodging me as well unfortunately *Edit: I did this to fix the two busted cables I had on my wiring harness and it still died on me for some reason I can’t understand

U where right I fixed mine this morning

This was very very helpful, I have the same issue. Thank you for your detailed video

I’m going to check that thank you

Nice catch! Good video too!

Good diagnosis check your continuity first next time though

Hey randy I love your videos you inspired me to make my own KZfaq channel may I ask what you use to film with?

I never knew about this channel lol

Nice work Randy stay warm

Great video ! Thank's !

heck yeah another great video , great info thanks

That was amazing and saved me so much time and money!

How did I not know you had a second channel,, what,, Liked n Subbd

Great information i have the same problem with a Gp 2006 .thanks for the video

Omg this was my problem too thank you 🙏🏼🙏🏼

THANK YOU! THANK YOU! LIFE SAVER BRO💪👍

Muchas gracias me ayudo a arreglar mi carro tenia los mismos clables cortados

sorry Randy, i was too curious to wait for the 2nd vid on the main channel lol

PLS RESPOND. I have this issue i spliced three wires and the car still wont start any help??????

How do you check for continuity on the wired? Do you have a video for that? TIA

I would've gone with tps sensor as well

Remember your friend said they told her she had an electric fuel problem? Well this may be it

A rubber lined P clip mounted using the close by upper engine mount bolt would keep that harness clear of any chafe hazards permanently.

Thanks for the heads up Randy.

Great catch Randy

Great job randy

Great job, Randy!!

Heater hose cut down the middle

RANDY! Great channel!

Lmao, this was my EXACT problem on my car. A bunch of codes came up and my car went into reduced power mode

Great job
