2001 Chevy Impala LS 3.8L
I’m having trouble with my Impala, and it’s not giving me a check engine light which is very frustrating. It drives fine, just when l sit still it runs funny. The problems l’m having are:
1.) Hard start
2.) Idles up and down
3.) Constantly shuts off
So far l’ve changed the mass air flow sensor, throttle position sensor, and the MAP sensor. What can be the problem? PLEASE, HELP!!!
