Well this problem surfaced last summer and went away only showing up at the top of the track my last time out in the fall...Did a few upgrades putting on a front mount and installing a Bailey's extreme chip...
First time out this spring the sputtering and bucking /missing is back...Most times it only shows up as it ramps into boost other times under light throttle during regular driving conditions...Sometimes a check engine light sometimes not!! No mal codes
Here is a list of things Ive done thus far:
1. Tried a known good coil pack and module
2. known good ecm
3. Tried both my TT chip and Bailey's chip making sure translator settings were changed
4. Verified grounds behind the pass head, checked wires going to starter
5. Put on a known good ls1 maf
6. Put on a new TPS sensor
7. Checked all i.c. hoses, maf hoses, and vac hoses
8. Checked connections on the back of the alternator and traced hot wire all the way back to connections at the tank.
9. Unplugged cam sensor to drive it in batch fire went into boost gradually maybe 5 to 7 lbs and it back fired and loud pop out the exhaust and the car shut off...Plugged back in the cam sensor car started right back up...Is it normal to do this in batch fire?? Is batch fire only to limp a car home ??
Dying to get this car back to the track with the front mount and I ported the housing on the turbo to get the boost creep under control..Any help appreciated!!!
