BUICK REGAL GAS PROBLEM

1990 Buick Regal • 6 cylinder FWD Automatic • 110,000 miles

Will a MAP sensor keep a 1990 buick regal 3.1 from starting if I have the proper fuel pressure and spark?

A bad MAP sensor can potentially cause all sorts of issues.

1. A rich or lean fuel mixture. You may notice a gas smell even after warm-up and/or pinging at random times or all the time or whenever.
2. Excessive fuel consumption (rich)
3. Rough idle
4. Hesitation

You will especially notice the hesitation off of idle when you first give it gas. The engine may even die if you don't give it enough gas off of idle.
