my buddy has a 97 TA. his car has a random misfire code i believe. it has gotten a new opti, crank sensor, plugs, wires, and fuel pump. the only real mod on teh car is hooker LTs and corsa catback.

the car barely runs once it gets hot. i think you can floor it and only go like 40 miles an hour or something. he had trouble goin over a small hill.

we are putting in a new opti right now to make sure it wasn't a bad one. compression is good. what should be checked next.

 

air and fuel would be a big one. make sure there arent any vacuum leaks and the plug wires havent been fried on the headers.

 

forgot to mention cats glow red hot

 

how did he extend his o2's?

 

Plug in extensions

 

I had a similar problem with mine and it was caused by a couple of plugs wires on the headers. I would check the plugs wires. Good luck.
