Did you replace the PCM recently?...or during the swap?
during the swap
Do you have a stock PCM that you can try. The other guys earlier in the thread may be on to something.
Do you know how to check the injector duty cycle with a DVM?
I'll throw my gt pcm and give it a try
No i don't
Well yea, check for vacuum leaks and swap the PCM. Be sure to update.
What MAP sensor are you using? I hope you switched over the the 2 bar L67 MAP otherwise the PCM thinks you have a 2 bar when you are running the stock GT 1 bar.
I am almost 100% on that is what it is. I bet if you throw your GT PCM on the car it will idle better.
GTP map
I'm kinda woundering if the pcm has a bad flash, now my ses, low oil light, brake light dont come on now
I was hoping the MAP was the answer as suggested by pure2sin. Damn!
Before you put the old PCM back in make sure you check your grounds, battery and alternator. That's about all I can think of.
Well after almost giving up for the day, (stock pcm did the same) I grabbed my gt idle air value and swapped them and guess whet she purred like a kitten
Good to hear.
Just weird it never set a code
Oh man! Great!
Since it didn't set a code I'm wondering if there is something wrong with the PCM. The return signal from the IAC to the PCM has to be within a strict set of parameters. If no code then WTF.
I'll have to remember this one!
I know. If I disconnected it and started it, it set right away. But I think i'm going to order a zzp pcm unless someone here has one better
You might want to go with overkill.
I wonder if anyone else has an opinion on that.
When I did a SSIC I had similar symptoms as you are having. And it was Vaccum leak.
I woundering about theres but never could find any infoQuote:

Let me guess, no code...Right?
Nope. I let it run for about a hour and nothing. I can shut it down and restart it but if it sits for couple hours it just cranks
So you're running the flashed PCM now?
