    Default Problems at Idle

    Alright recently I have had a idle problem. Truck runs great has no power issues and everything checks out fine. When it idles it sputters or hickups a little. Never dies but just constantly does it. Anyone have any ideas what this may be? To me sounds almost like a vacuum line or something

    In the absence of a vacuum leak clean the MAF and possibly the throttle body. I had the same symptoms when I bought my truck, and when a qualified mechanic couldn't find a vacuum leak he did exactly that; both were apparently a complete mess.

    Cleaning them up resolved the issue for me, so perhaps it is a path to go down if you can't find a vacuum leak...

    Well it has a brand new MAF sensor and I cleaned the throttle body the other day still same old thing. This ones got me stumped

    Idle Air Control Valve... You CAN clean them but they are extremely fragile. I always just buy a new one since they aren't that expensive.

    im stickler on O2 sensors they go bad and they are cheap but will cost you lots of money after you found out that what it was shop can't check it it will read going down the road but at idle or shut off it reset it self i maybe wrong but it happened to me try it
