a miss at hi rpm
I have a miss in the motor at higher rpm while driving. At an idle it is smooth. It was in the shop for 1 day and no one could determan the problem. So I have started replacing several things First thing was the EGR valve. The original one had a leak. NextI had a 42 code in the computer. So I replaced the Distributor . Which was only 2 yrs old. That took care of that code. So know I have no codes showing up in the computer. I replaced the Throttle postion sensor. Still no change in the hi end of the idle. I replaced the gasket under the TBI . Tomorrow I will be pulling plugs to check the gap. If anyone has any other ideas PLEASE let me know. This is drving me crazey. The engine been this way for about 2 weeks.

Broken valve spring, check the compression, bad cam lobe, spark plug wires, plugs, clogged fuel filter.......
