I noticed the other morning it stalled a couple of times when I was stopped. It seemed to go away later but now its worse and doesn't want to idle and stalls unless I keep my foot on the gas. Any ideas? Possibly the fuel filter or maybe something else? Any suggestions or help would be greatly appreciated. Thanks. Chad |

Check engine light on? Does the speedo work? If so get the codes/fix speedo,if not see below. 1st have the battery checked,#1 cause of your problem.If the battery tests good time to SeaFoam the induction system. |

The battery is new this year. The speedo works. The check engine light is not on. Not sure what it could be. Thanks. Chad |

If the battery truly tested good I would have the induction system cleaned,does wonders buy cleaning all the carbon out of the TB.Can try and get a can of Throttle Body cleaner and taking the intake hose of the TB,start up the KJ and spray into the IAC area(will have the feather the throttle to keep running).That should help the idle problem. |

I had a problem like that last year. I'd try to start the car and the engine would rev up only to cut off a second later. Took it to a shop and they replaced my idle air pump (i think?) |

Take the throttle body off, cleand the deposits off the blade, body, remove teh IAC (idle air controller), clean the pintle of the IAC, Clean teh seat of the IAC, clean the air passage orifice. |

I had a similar problem a while back and I did what Straight6Jeff recommended and it has been fine ever since. It is very easy to remove the throttle body and clean the build up off everything. |
