Rough Running at Start.

[JohnHaggerty]

85,000 miles. Over the last few months I've been seeing a rough running engine with little power after start. It doesn't always do it, but it does repeat. I turn it off and re-start and then all seems normal. Any ideas?

Did you ever find a solution?

No. Still does it. All's fine then one day runs rough after start. Turn off and re-start and runs right. It's got me stumped. At least it goes away.

You might check the AC clutch activation wire closely and see if is rubbed thru the insulation on a pipe or anywhere it is fastened. Fan clutch and\or wiring is another place to check.

What year of truck? Have you tried to pull any codes?
