2000 Pontiac Bonneville • 6 cylinder 2WD Automatic • 200,000 miles

Dear sir or madam,
I have a 2000 bonneville sle. On initial startup in the morning the car starts up immediately as it has always done. After the first startup after that it cranks over and I have to floor the accelerater to start it, the car then races on until I engage a gear then it slows down. There is also a smell of exhaust in the car and seems to be more emission than normal.

Try cleaning out the idle air control valve/throttle body and see what happens
