i have an 88 integra with a d16a1. heres the problem, it will throw a CEL when it is warmed up, if i downshift, or give it a lot of gas. it smells like eggs also. i just put in a brand new NGK o2 sensor, and i have a relatively new cat(changed about 20k ago). i dont know what else to do. help?


also, the thread in the header is cross-threaded. so the o2 is about a turn or two away from being fully in the header. could that have something to do with it?


thanks!
