General Maintenance & Repairs - First time user to LS1 Tech and I am having some hard acceleration problems.

I assume introducing myself should be first. I am a 26 year old male named Adam living in the Chicago land area. I have raced and worked on cars for years now but my current 2001 trans am is my first fuel injected street car. The car is decently modified with a patriot top end and umi undercarriage, strange rear, tick performance trans.

My problem: any help would be much appreciated don't even know where to start.
If you get on the car hard in first gear "car rolling..... dropping the clutch at 4 grand or so" the car jumps so to speak and interior lights flash, all dummy codes/lights go off, the car proceeds to run like shit. When pulling over and turning the car off it resets itself and seems to be running fine again. I really would like to get this issue taken care of..... any direction would be of help. The only thing I have to go on is I did not reinstall the transmission stop located on the top of the tail shaft of the T56. would this allow more play causing something live to arc when the motor shifts under hard acceleration??

Sounds like you have a loose connection. The most common place for this is at the alternator (positive lead from battery) and at the fuse box (positive lead from battery). Also check all the grounds that originate at the battery.

i had same problem with my 98 z28. come to find out that my grounds on the back of the heads were loose

I had the same problem^

Maybe the battery is hold down loose or missing and shorting out against
the a\c or something.

alright thanks guys I will check my battery, back of the heads grounds "any recommendations on how to get to them?", and all battery positives and go from there.

The grounds on the back of the head are hard to reach. There should be three on the back of the driver's side head. Might have to remove the coil packs and reach back there. They are 15mm bolts and the grounds have eyelets. So just make sure they are tight.

Sounds exactly like a problem someone else had with his built ss at the track. The battery would move and short out on the AC canister behind it.

had the same problem, ground on the back of head
