My 1990 Celica GTS is not running smooth and smoking really bad when idle. I'v been told it needs a catalytic converter. How can I confirm the catalytic converter is bad.
hi, first things first i cant spell i know this so dont correct me. :laughing: im joking but i cant spell. yea uhh i dont know that much about jap cars but i know that if its smoking bad oil might be getting into the cumbution chamber might be a head gasket, but i dont think theres a way to check the cond. of the catilatic converter but there not that much, i dont know how much you are looking to spend but a fairly good one is under $100 new. sorry i cant be of more help.
