it doesnt always do it. if i give it 1/8 gas it'll go up to 1800-2000 rpms just fine. and shift. but if i give it any more gas then that. the rpms will drop to 1100 and the engine will shake and studder and itll try to go through the rpms. sometimes itll clear itself. and run fine for 3 mins then it goes back to studdering and popping. ive replaced all the spark(coil, module,wires,plugs) im thinking of replacing the pickup. but i dont even know if its a fuel problem :/

when i brang it to the shop to get the plugs replaced(pain to do with headers) it ran perfect for 4 days. then the problem back

this does the same cold and warm. pls help me. ive been dealin with this problem ever since i put the tpi in 1 year ago(stopped for 3 months then came back) when i brang to the shop it was throwin 3 codes. maf sensor(its brand new), O2(just replaced, not throwing code anymore) and VSS(not hooked up since tpi swap)

this on an 82 T/A TPI(not stock duh) im about rdy to throw off a cliff :/

 

anyone?
