pcm
Ok cool im about to go change out the accel coil and install the stocker one. With the MSD wire set its not sparking out the wires it just has the miss/poppin/cutting off problem. Would you happen to have a spare PCM for a 97 lt1 auto?? Just wanted to make sure my PCM for less tune wasnt jacked up or the reprogrammed pcm they sent me is bad.

accel coil
Well replaced accel coil with stocker and still the same. What causes the belt to squeeek when you floor it on an auto and revs go up to 4500rpm. Im running an gatorback belt ?

Guys let me know what you think. Im running out of options here all the sensors have been replaced. Is it the tune or is it the opti. Pcm4less did the tune and added the power tune option. Let me know what you guys think

fp regulator
Guys when you unplugg the vac off the fuel pressure regulator, is the idle suppose to change?? I called pcmforless and talked to keith and he said it might be a mechanical issue not a tunning issue. Before I take it to a shop is there anything else i need to check? There is a shop here in humble that charges me $80-85 to tell me whats wrong with it. Is that about right?

Ok guys can somebody check out the videos? I have replaced the stock fuel pump with a walbro and jegs wires with some msd.

The car is idling bad and it STILL CUTTING OFF AT HIGH RPMS, I NEED SOME ADVICE WHAT TO DO NEXT????????

what kind of tools do you have access to? can you watch timing with some sort of scanner....laptop & cables? no liability here but i've done it...check your intake runners and any suspected locations for vacuum leak with some brake clean, carb clean, or an unlit propane torch. your engine will increase in rpm if there is a leak.

Cats have been gutted out, there is no restrictions on the exhaust. Im gonna try to find a scanner. My budy has HP TUNERS. Can we look at the sensors,timing etc with that tunning program? I can find that thread about the cable for obdII and software to log in a laptop.
