4.0 stuttering under load on start
My 94 ford ranger is stuttering under load on start up doesn't matter if it is warm or cold. The problem is intermittent. If i press clutch in fast enough it will rev up normal and when i drop the clutch it will stutter for a sec and resume normal functions. It passes koer and koeo. Tps is correct voltage. cleaned maf sensor a few months ago. Checked plugs look new still. vacuum is correct. any ideas? could it be the fuel pressure reg or the iac? how do you test if so. Any input will be greatly appreciated checking fuel pressure tomorrow.
