Wierd idle

First post here guys, have found alot of usefull info. Every now and again my truck idles wierd, shakes and sounds like it's loping. But I can turn it off and start it back up and idles and runs fine. Any ideas what sensor or something could be the problem. I've done the 10k mod and shimmed the fpr.

Is your truck a manual transmission, if so does depressing the clutch, or releasing the clutch quickly cause or eliminate the problem?

10K does cuse rough idle from time to time. Did it do it before you did that?

To start out,,,,Check the connection to the ICP & make sure it is not loose ,corroded Or leaking oil.....Unplug the ICP when at rough idle & see if it smoothes out....

There is always going to be a "Phantom" idle from time to time it appears. I think everyone on here has had it at one time. It could be your oil.

Thanks for the replies. I will have to check everything and try unplugging the icp. I know it is probably just going to be this way, just wondering if it was something to worry about.
