Default 93 grand am, need help - 05-18-2007 , 12:48 AM






Have had problem that has probably been discussed lots of times, but heres
mine again. Car runs fine till stopping at traffic light, stop sign. Then
service engine soon light comes on, car idles fast, kinda up and down idel.
Starting off is kinda jumpy, but once going runs fine, SES light usually
stays on. Friend had code check one time, said heat sensor. Got one but
didn't help. Car doesn't run hot, kinda embarrassing when stopped in traffic
with crazy ideling. I've checked every vacuum hose I can think of. Oh yeah,
catalytic converters don't last long, 1-2 yrs, so figure some kind of
emission problem, but what. Any info appreciated. Thanks
