I couldn't never figure out what it was because it never throwed the code to I took it to a mechanic shop that has the big computer to read the computer .. and bam it picked up the po300 code .. because I took it to AutoZone it wasn't showing up .. I took it to advance auto part it wasn't showing .. them obd code reader are grabage trash at those places.

Any advice on a U0073 code? Everything started when I had s misfire, changed my plugs, coil packs, and valve cover gasket. Ran great and then got the U0073 code. It’s a no communication bus a off code. Got a new battery, new tcm, checked all fuses, new ignition switch,new maf sensor, checked wiring and grounds on tcm and ecu. If I clear the code It will run great for 3 on/off cycles and then the code comes back on? When code is on it goes into safe/limp mode and you can’t drive it until you clear the code again. Any ideas on what my next step may be? I’m going crazy and broke trying to fix this! Maybe a sensor or solenoid? 2006 Chevy hhr

Thanks for the informative vedio. Is it true that a bad ignition coil will affect either cylinder 1 and 4 spark plugs or cylinder 2 and 3 spark plugs. As to your example spark plug 1 and 4 were not sparking.

Catalysts converter I bet is messing up? That coil pack might be cause it?

Que cables le conectas cuando chequeaste los capachunes de las bujías ???

Thank you for the film. Can you tell what grease goes inside of the ICM and possibly where do you apply it? In my coil compartment ( to the very right under the bigger connector) for the ICM there was a blob of some grease. Is it supposed to be there? And if so what grease is it? For the new ICM AC Delco gives a pack of grease to put on the female connectors, but where exactly? And nothing said to put into the coil compartment. Do you put any grease on the metallic plate of the module? My original Module is the same (2003 Chevrolet Cavalier, Eco Tec 2.2 engine). What is that yellowish crystallized stuff in the old coil pack? It is the same in mine.

I changed coils, spark plugs, fuel injectors, mas sensor, map sensor and still getting PO300 code and the care has a rough idle. help

2 things: His Misfire was a simple/ fast fix. And secondly why switch the screws out to TORX? Same thread pitch? Even so; Its uncommon? I dont like having more tools then I need?

does the 09 Cobalt LS 2.2 actually have an IAC sensor? or is it part of something else on that version? If it has one not sure where it is located but I assume it would be on or near the throttle body

Hey how's it going?? I have a 2006 Chevy Cobalt and I'm having problems getting gas up to the top also when I press in the fuel valve nothing comes out have replaced fuel pump and spark plugs but still no luck can u help wit some tips on trouble shooting

I have a 09 chevy malibu 2.3, it also has a misfire but it's very random, no code while the engines running but it will idle a little rough sometimes at a light and will jerk. After a little it'll go away, took it to a shop and they couldn't duplicate the problem. Started out by replacing the spark plugs. It accelerates and drives fine just at idle it has a slight misfire

I got a question? How do u check the transmission fluid?

What causes my colbalt to guit when I stop at a stop sign or just idling in park . But when I'm driving down the road it runs great .

What do you ground the spark plugs to?

I have a 2007 chevy cobalt it's has a random misfire I tried everything no luck what should I do? I put new spark plug even replaced fuel pump

How long did this repair last?

hey man good video but i have a question maybe you can help me out but my cobalts check engine lgth blinks only when i go faster any chance you migth know or anybody can help me what is the problem ..if is a missfire or something more then that ,,?? thanks

I got code do cylinder 4 misfire I replaced coilpack and spark plug the chek ingen went out but is still giving the code for cylinder 4 misfire

What happens if you don't ground the spark plugs?

Better Put Compression last place on the description lmao

Thank you for video was very helpful except I would like to have watched you put coil pack back on the car

Should show the injectors with just power without trying to start and check for leaking injector

I really hope new plugs were put in, they were fried. Probably all it needed

I can see the immediate problem before even going any further into the video.....the throttle plate is stuck open.....so my guess is you either cleaned the plate so it could close or you replaced the throttle body.

Hi

My question is. I’m getting a P0171 code.
