hello i had bought a 2001 camry le 2.2 with a blown motor. then i bought a totaled 2000 camry with 120k that ran nice. Then i had swapped the motor trans and harness all in one piece from the 2000 into the 01. plugged it in bolted it up everything hooked up topped off ect. The car starts and runs, no check engine light, but it boggs down low and the manifold/catalytic converter heats up red hot. It seems like its getting to much fuel. Is there any differences between the 2000 and the 2001 harnesses? or any ideas on whats wrong?

 

It had a bad map sensor, most likely why it blew up in the first place.

 

Thanks for posting back with the find?
