rough Idle with a 94 explorer

[ahasver]

while idleing my explorer vibrates every once in a while like the engine has a miss in it. i've replaced the fuel pump, and the fuel filter, the MAF sensor (had some acceleration problems MAF solved part of it.) now i have a miss and am at a loss for what is causing it. i have new plugs and new plug wires. when i step down on the gas to take off the car sputters and then starts picking up speed after a few sputters. i am at a loss. the engine light never came on. the ford dealer found zero problems other than the MAF sensor. so now i am stuck.

did u ever figure it out because mine is doing the same thing

not yet i was hoping someone here would have some insight. the only things i can think of are the spark box and the EGR valve. both together are about 200$ and fairly easy to fix. going to be a little while before i can afford them both. so i am waiting to see if someone has some insights to save me some money

Clean your IAC Valve, if the valve stuck or dirty it will cause the problem.
