Hello, Have a 95 GT w/ 165000. Lately, upon starting, The engine revs up & down on its own. Try driving it and it bucks even on the highway, almost as if there is no gas. That is not the problem. Exhaust rumbles (After-fire) when this happens. Car wants to stall (check engine light flickers) then comes soaring back. Pull off the road, shut it off, immediately start it up and the problem goes away. Runs perfectly. let it sit for awhile, start it up and the problem comes back. Frustrating but to the point where its not driveable. Because it is so intermittent, mechanics cannot find problem.....suggestions? Thanks

Try cleaning the MAF sensor.
