Hello, a tip... if doing all this service the engine continues with unstable idling or accelerating alone, change the 4 orings that go on the throttle body shaft (TBI)... the shaft has a small play in the bearings of The needle and the seal dry out over time, causing false air intake... almost nobody knows about this trick! good luck everyone, greetings from Brazil!

Hi Dale, been watching your videos for years, thanks so much. Like Kevin below, I too have a 94 YJ w/ 72 k original miles that has a strong rich gas smell from exhaust. Never had CEL, no apparent leaks from aftermarket header. cat and exhaust system replaced 2 years ago. Have good gas mileage, idles well, starts immediately and I replaced O2 sensor two days ago, checked MAP (good voltage with decreasing voltage when vacuum applied), checked TPS with good results, did fuel injection pressure test with numbers slightly higher than your video (34 psi idle with 42 psi vacuum line disconnected, with no change with throttle applied). Cleaned throttle body per your video. No visible leaks from injectors, but after watching your video ordered new injectors just because and will install when they arrive. I have done "exhaustive" forum searches and out of ideas. Problem is above my pay grade and think I need a professional. It appears you might live in Oregon as I do and was hoping you might have a shop recommendation in the Bend area. Thanks again!

Great video, thank you! I have a question if you have time, I checked with multimeter and checks out good, no dead spots all the way. Is it still possible that the sensor is still bad? For reference, when I am driving, jeep always stalls at low speed (0-10mph) and at (40-45mph) when letting go of the pedal. If you press the pedal pass it certain rpm it stops stalling, and also won't do this at any other speeds. Any ideas? Thanks in advance.

@blownaway4371 7 күн бұрын

I noticed on my throttle body that there's room to rotate/turn the TPS a bit. It looked you just stuck it on and screwed it in. And the meter started at 80ohms. Are we supposed to rotate the TPS to the lowest reading, THEN tighten? Or does it matter? It would be nice to see you add one of these 62mm complete throttle bodies! My project is a 01 Dakota with the 2.5 4cyl. And a common upgrade is to use the 4.0 T/B. So more would be better RIGHT?? 🙃

@Mrshibbs3291 Жыл бұрын

My 99's throttle position sensor was throwing a code but it was my clock spring that was faulty sending a short to a shared ground in the PCM causing the TPS to malfunction. The codes wouldn't clear until I pulled the horn relay which confirmed the clock spring. Was causing idling, stalling issues, and acceleration issues.

2001 Grand Prix with a 3.1-liter motor, started idling high after good and warmed up. No codes at the time. When motor would idle too high, 4T65E trans would shift super late under light throttle. About 25 MPH and 2,500 RPM before it would hit 2nd. gear. Was OK the next day. 3rd. day, high idle and late shift again! This time the check engine light did come on. Code P0121. Scanner TPS angle percentage at idle shows 0 sometimes, and sometimes 0.39% and ~ 100% at WOT. One time while sitting there idling fine, ~ 700 RPM, all at once the idle kicked up to ~1,300 RPM all by itself. I looked at the scanner, now TPS angle percentage went up to 2.75%. From my readings it looks to me like the sensor IS receiving the 5V reference, and my ground in good, and my reference voltage is changing and being sent back to the ECM. My voltmeter is at my buddy's garage right now, so I could not do the voltage testing at the TPS connector, as you have outlined. I'm ready to take a chance based on my findings, and just install a new TPS. What do you think? Reply

@Pitstopcomponents 3 ай бұрын

I read about the Clockspring getting shortwired and cause 12v supply to PCM...same issue as you have, it is because the Airbags operate on 12v, while the Cruise control works on 5v, if shortwired, the Airbag-positive can contact a Cruise control positive causing it to get 12v too.... check that as soon as possible, as it may fry your PCM one day or cause other damage to Electronics

Hi quick question - I have a 94 YJ and it has quite the rich smell - I have replaced the O2 sensor - and have wondered about the sensors you mentioned MAP, MAF, IAC, and TPS if changing them would help - or would I be better off looking for an exhaust leak? I have checked for any stored codes and there are none - any advice would be great. Are the other sensors "easy" to test as well with a multi meter? Thanks

Is your fuel economy terrible? Could be leaking injectors. Maybe see if the fuel pressure test. See if it holds pressure

@dt5644 Жыл бұрын

i sure wish i lived close to you. 1995 yj 2.5 low idle, and the local mechanics cant figure it out. when i bought it 4 months ago most of the sensors were originals. so i replaced them all, map, 02, iac, tps, air charge sensor, new plugs, wires, cap rotor and coil. when i first put the tps in it actually idled normal for about 10 mins then died back down to 300 rpm. and at temperature that is where it idles runs rough and has a miss. at speed seems to run fine. fuel rail pressure is at 31psi. I am stumped and wishing i had never bought it at this point. Any subjections??? any at all??? anyone?? other than sell it, to deep into it now for that.
