what can cause my motor to expire short on the RPM after the car warms up to about 190 before then it doesnt fall down early but it seems to be a problem sum where in that someting isn't dialed in right can any help me or give me any suggestions I don't thing it's hot at 190-200 but it will fall down at about 4000 rmp's if I get on it hard after itr's reaching operating temperature and when it dows I can smell gas...thanks in advance

It's like hitting a fovener or something and it stop firing then a few seconds later it powers or sparks back up. It's doing this around 4000 RPM when I am getting on it strong. I am using my factory tach and I thought it would still fairly read accurately. I was told that I am hitting the rev limiter and the tach isn't keeping up but I don't know but when I hit the rev limiter when I said it the car bounce's so to speak and it's not bouncing its fall down just like a govener or something...

could be an ignition module problem, judging from the coincedence of heat + problem

factory limiter is 6250 and if it were the case and tach were off it'd be the same in all gears....could be a secondary ignition issue..plug , cap rotor or wire
