Hot or cold, the engine stutters really bad when I hold it just higher than idle, mabye 1/8" of pedal travel. Problem is, thats all I need to keep the car going at speed, so its getting really annoying. Any throttle position above that the engine runs fine. Throttle response in nuetral is great, unless I try to rev it slowly from idle, then it bogs pretty bad. In gear, once I get the pedal past that point, the car accelerates smoothly.
In the last few weeks, I have installed new Autolite platinum plugs (proper gap), new wires, and replaced the timing belt. The miss was there before any of this was done, but was barely noticable and has gotten worse since. Reset PCM with no change. No CEL. New TPS installed, no change.
What do you think? Coil? Now Im thinking it could be fuel realated.
