Getting strange lag. Gen2 ATX.

[Leonard Emery]

So im trying to diagnose a problem with my 94 Gen2 ATX. I get no check engine light since i did the Cam sensor. Replaced plugs, Cam sensor, Crank sensor, Coil pack, ICM and Fuel filter. When casually driving the car its has a bit of lag from about 1/4 to 3/4 of the pedal. Put it to the floor and its all there. Its strange lag. It almost feels like im not getting an adequate amount of spark. If it were the fuel pump would it just DIE or slowly stop working properly? Im going to dump $150 on plug wires today and see if that works. Other then MAF, fuel pump, and TPS, what could possibly cause this? Thanks for your help!

Did you check if there are any codes stored? Did you have old codes before you replaced they parts? What's the fuel pressure with and without the engine running.

good guess would be the tps has a flat spot on the resistance curve, so the pcm does not respond fast enough to the throttle opening, and it goes lean for a time. try a known good tps.
