Had a vacuum leak at fuel injector replaced all the o-rings and 1 bad injector and no longer have a vacuum leak. now the car will not idle and almost die when warm. but if i create a vacuum leak the car runs smooth. replaced the MAF sensor and the ICV. already reset all codes and no codes have returned. they were all old codes. Does any one have any good ides what the problem maybe. 2001 grand am gt 3.4.
