a few times running my car last night, at the top of 3rd gear it almost felt like it was pulsing, or like surging. it did it like 3 times, but then didnt do it after that. i have a 93 with a new motor and dp, gutted cat, hose job, and pettit ast on the stock computer

 

anyone?

 

It was warmed up right?

 

yea, warmed up......my a/f reading is usually at like 18-19 when i give it no gas....but when im fully on it, its like 10.1 whats that mean? anyway, it doesnt seem to do it anymore...im just cautious about every little thing right now, i just got it

 

I also was cautious about everything right when I first got it. Every time it made any sort of noise slightly different than what it normally did I freaked out!
