Sooo my mechanic shop has finally determined the plug wires have holes in them... a month later... from when we started this... now that ive spent all my money chasing ghosts... fantastic.

Thanks to all who replied.

 

so again we replace the starter, spark plugs again, new wires, cleaned all the sensors, took out the K&N and put a stock air filter back in...

and still the same problems.

Anyone wanna buy a Camaro!?

 

The gas covered plugs may be your clue that gas isn't being burned fully, check to see if you are getting a good spark at the coil pack terminals. Maybe coil pack(s) are failing?

Did u check the other things in my last post, and check the sensors mentioned by another in this thread?!

 

Checked and replaced nearly every damn sensor in this car. THe only one that was not changed was maf.

It gets tons of spark and fires right up now, and once you get it warm, the car drives like a dream. Something about it sitting for 7 hours overnight causes it to go back to choking. Now that we've changed everything it definately doesn't take as long for it to get warm and drive right, but it's still a good 4-5 minute process.

You can get it started and keep it revving and slam it in gear and take off and it almost seems that the gas pedal has very little influence sometimes. It's definately going, but it jerks and tries to die and catches (providing your foot has the pedal down) but you let it jerk you up and down the street for a minute with it popping and backfiring, and after a minute or two it seems like it just straightens itself out and it's golden.

I can do that in the morning (7:50a) and get to work at 8, park it til lunch 12:30 and it will fire right up. Drive to lunch, come back, park it, leave it til 5:30 and it will fire right up. Take it home and then I could still fire it at midnight or 1..... but come 7 am...back to crap.

 

In other words, still no fuel pressure & injector check?

 

They checked fuel pressure when they replaced the fuel filter.

The injectors were fine. They've basically taken apart and reassembled the engine.

 

Did you try testing to see if you could rule the MAF out? Someone had said, and I agree, unplug the MAF, and start it up. If it runs the same way, it is more than likely not the MAF. If it gets better, than it is probably your culprit.

 

Did, runs the same. Not MAF.

They are getting two more days with it and i'm effing done with it.

 

Have you sprayed the throttle body to ensure the butterfly valve is not gummed up and varnished?

 

Yes, checked and cleaned thbody. All is good.

Everything within spec on every computer system you can hook to it. It just hates being cold, but still gives prefect readings.I've gotten 3 different mechs to tell me the next step is replacing the PCM.

I'm done.. it's been too much trouble. Great first Camaro experience for sure.

Thanks all.
