i have a 90 cavalier with the 2.2 tbi motor. recently its been acting up. it will start and rev high and be running extremely rich. driving it drives fine but the idle stays real high and he motor stays running rich. i've tried replacing the ecm since theres been problems with it before and tried replacing the egr but its still doing it. the only difference is that since replacing the egr its random now. and the worst part is that theres no ses. any ideas? it also has a auto trans.
