Engine fumbles under acceleration and then the check engine light comes on for a min then goes off. It doesnt do it back to back but it is getting worse. Now it hesitates at cruising speed with little acceleration with the light. It still has power but its a problem. I think its plugs and plug wires.
I have had people say its a throttle possitioning sensor, a bad sensor, and other things. The car has 111,000 miles and no recorded spark plug change. Any Ideas? im open.:confused:

You might want to tell us what it is and you probably want to get the code read so you can see why the light is coming on.

It is a 95 z28, 6 speed. 111,000 miles. the car usually has only a half a tank in it while it sits, but it doesnt do so for more than a week and a half at a time. With my temp in side my garage changing drasticly it may be condensation in the tank with a dirty fuel filter. fuel cleaner is now running in the system and a computer check is in line for friday. What would u guess?

Dirty mass air flow sensor.
