I have a 1991 Pontaic Grand Am with 180,000 miles.
The car was running good until the check engine light came on. Since then it starts rough often taking 2-3 tries before it turns over. While idling it seems like the throttle is wide open. The spark plugs were replaced but didn't help.

Please diagnose the check engine light. This will give us an idea as to which part of the vehicle is failing and we can better give you an idea. Thanks!
