I have a 94 camaro m6. I have a big problem with hesitation in the whole rpm range. It seems that it is fine when i first start the car but as i drive, it progressively gets worse and once it gets to operating temp... i can be beat by a stock honda civic. I recently brought it to a shop and they told me i had a couple of cylinders misfiring. They changed all the plugs and wires and they told me 6 out of the 8 plugs the platinum was completely burnt off. i paid $250 for that job and it still hesitates just as bad. what could be causing it to hesitate so bad at all rpms when it gets hot? I have changed plugs, wires, fuel filter, coil, iat, cleaned my TB, changed mass air meter...still no results. Soon i am just going to have to sell it and buy my 5.0 back. Please help!

 

Fuel pump or Opti. That's about all that's left. It could also be the Ignition Control Module. They can do that when they get hot. No codes?

 

no codes. if it was the icm itself wouldn't it be hard to start the car?

 

Not necessarily. Semi-conductor devices can start to break down as they heat up and work fine cold.

 

do u know the part number for an ICM for my 94?

 

10483139

 

ok...thanks for the replies

 

No problem. Come back and post your results.

 

i just installed a new Ignition control module ICM....but it still hesitates like it did before...any other ideas???

 

Clean your MAF. You need to remove the screen to do it properly. Use some carb cleaner and q-tips. Replace the screen, re-install, and then disconnect your battery for about ten minutes. Hook it up and say goodbye to the hesitation.
