I have a 95 buick Riviera, what does engine stutter during acceleration mean?

I have a 95 buick that has slow acceerleration when you press the gas. In addition the harder you press the gas the engine stutters. The check engine light comes on and off. I was thinking (or hoping) this was a wire or filter issue. Any ideas?|||Start with checking the air filter.


If that is clean you might have a fuel supply problem. Check fuel filter, fuel pump.


And if all that is fine, you need to check the head gasket for a leak.|||My guess would be a MAP (Manifold Absolute Pressure) sensor. Check the following web site under MAP sensor: http://www.aa1car.com/library/1999/cm699鈥?/a> ...Good Luck...
