cannot figure this out???????? Mods are -f14 cam,pacesetter lt's,ls6 intake
Have had many h/c combo's but never had this problem till now.
Car sputters and backfires under load-(driving in fourth and nailing the gas)
Also when i go full throttle, as soon as it hits 4 grand it sputters and pops and loses power.
Mikey at rapid had it on the dyno for a tune and everytime it hit 4 grand it would do this. Mikey said the fuel was not the problem but check the ignition.
I have checked the plugs and put new wires on it but no dice.
The car is a 98 so i beleive you can switch the left and right coil packs???
Not throwing any codes.
I don't know where to go from here. Pretty stumped at this point.
Any help would be appreciated greatly????????????????
