cant figure car out

Car is 89 lx with 5.0 explorer intake and p heads . start it up and it idles fine .give it some gas and it starts busting out @ maybe 2800 rpms . Sounds like it s on a twostepp...Can cycle the switch off and on 3 or 4 times and it goes away.... Sometimes I just let it idle a few minutes and drive on down the road and cut switch off and on and it is gone , by the way car is straight drive ,New plugs ,wires , cap and rotor and it still does it , HELP Also have tried a different computer

check:
timing- 10* btdc
fuel pressure- 38 with vacuum disconnected and plugged
also check for vacuum leaks and sure the egr is working

what switch are you "cycling" ?

p.s. you can bump the thread to help it get to the top of the thread list.. just please dont keep bumping it constantly. but creating repeat threads just clutters the boards. so i will go ahead and delete the other thread u made.

Have you checked the injectors? I would get a noid light to be sure. And make sure the eye is functioning properly.

Also forgot to mention coil. That could be a main suspect..

If not coil check the tfi module. A test procedure can be found in the stickies under useful information.

Might also check the ignition switch. Make sure there is power on all the wires there should be.
