O.K. I know, get the code checked out, I just don't want to pay $100 for someone to say it's a something-something error code. So, that being said, someone stole my datalogger, stereo, sub, and radar detector, on Mon night out of my driveway

O.K. on to the problem, I have a 1990 GSX, Dejon Tool intake (new), K&N air filter(new), no cat, Manual boost controler, Nology Hot wires (new), NKG plugs(new), O2 sensor (new), idle speed stabalizer (new). The car starts great from cold, and runs great (the good) untill I shut it off when it's up to running temp and restart it, then I get a CEL and it runs like it's not firing on all 4, if I let it cool down all the way and then restart, no problem.
