I just did a top swap on my 98 GP GT ran perfect before. Now to get it to start I have to hold the gas down alittle and it doesn't stay running unless i hold the gas. Only code is P0300 for a random misfire

Which tb did you use?

Double check your plug wires. Trust me....I'm pretty sure. You do have some exhaust on it right?
03-21-2012
The PCM is a gtp w\ a gt trans tune
I'll check the plugs again
03-21-2012
What year of PCM?
Who changed the tune for the trans?
What injectors?
What year tb/maf?
03-21-2012
98
guy from here from South Daktoa can't remember user
l67 inj
99 tb\maf

Why did your temp gauge swign up when the ign. was turn on?
03-21-2012
^this why the sweep?
03-21-2012
It did that after I switched pcm
I checked the plugs and got it started for alittle bit still had to hold the gas. after it died I tried to start it again and no go
03-21-2012
Are the ignition coils stock?
03-21-2012
yup
03-21-2012
Let's see. Your having to keep the TB open and your getting a P0300. Sounds like a vacuum leak to me.
03-21-2012
Sorry forget to say after I switched the around around the p0300 went away and started and had to hold the gas a little but now i can't get it started
03-21-2012
You check for spark?
03-21-2012
Yup good blue spark, I can get it to start if i spay some starting fluid in then I can get it to start and run
03-21-2012
Fuel issue? Maybe FP resistor or pump?
Make sure the pump winds up with key "ON". Then check fuel pressure at schrader valve.
03-21-2012
how would I hook a f\p resistor up on a l36 harness, I dont have a pressure gauge with me but if i push the value in it will shoot over the hood
03-21-2012
Oh, forgot you did the swap. So starting fliud gets it running and there are no other DTC's. HMMMM.
Still sounds like a vacuum leak. I know it's hard to check for vacuum leaks when it won't idle but maybe someone can help you...one guy with a can of carb cleaner and the other keeping it running at a steady RPM.
Edited:
Did you try unplugging the MAF?
03-21-2012
I'll see if a friend can help tomorrow before work. Yea i tried the maf no change. oh just noticed something the boost gauge doesnt move when it goes into boost
