engine has a misfire.. please help
so i changed the egr, egr position sensor, tps, air charge sensor, o2 sensor, thermostat, both catalytic converters, exhaust, plugs, wires, rotor, coil, then the clutch went out, got that fixed and the mechanic said i had a misfire but doesnt know why...because i wont let him have my truck any longer.. took a week for a clutch job
could it be something to do with the ignition

Could be the stator/pickup in the distributor or the TFI module or even the coil. Are there any codes popping up when you scan it? Were all the CM codes reset when you replaced all those sensors?

EGR doing strange things will cause this problem. I still have to fix my EGR on my Ford, it does a little sputtering cold or hot because of it.

lol i think you were one of the first people to respond and help me a month or two ago, i thought it was the clutch the whole time, that was part of the probleem but not all of it...
i just did a compression test and there all reading between 120 and 140, is that ok?

yep, if the filter is a little blocked, it doesn't help. did you get the EGR replaced and clear that code? if so, the only thing left would be fuel delivery or something distributor-related, unless you replaced the module and internal parts already. outside of that, even with it being a computer-controlled truck, these things like to have a certain base timing range set or they tend to act up, or so I've seen.

yeah im waiting on the radiator to get here then ill be able to test the fuel system. ill let you know what it is and the ignition control module did cleared alot of the misfiring up so it has to be fuel delivery.i wouldnt doubt that the clutch ,fuel system and ignition system would all go out at the same time since the truck does have 234,ooo miles on it
