Y Well after putting lots of work into my car finally got her running. This is my 3rd Lt1 and I've seen the security light come on periodically with all of them. Wait three minutes and starts fine. Now. Go for a ride today and the sec light came on while driving. A few minutes after seeing that light i began to accelerate, half throttle and the car sputtered and had alarge power loss. Took the car home. Let it sit for a while. Took a drive, ran it hard, no problem. Light then comes back on runs like crap again. I understand that the security feature disables the fuel injectors. After some research I've found that the pellet on the key may be the culprit. Anyone got any suggestions? Thanks.
