idling ?

[joeyd50]

Been gone a while, lost the site,1994 4X4 3.0 V6 Automatic, 358000 miles, Truck runs great once it worms up, when I first start truck in the mourning now it wont idle, I got to keep giving it gas, was starting and idling fine up to a few days ago. Where should I start looking first?

Thanks

Joe

Try reading the computer codes, there's a great write-up on here somewhere. On my 95 I pulled the seat out so I could get to it more easily. (Didn't hurt to clean under there, either! )

 

Also check the wiring to your MAF, specifically the plug. Seems like every time someone's got an idle issue, it's the MAF. If it looks okay, try running a new ground to the body. (Whatever you do, don't try to clean the MAF, they never work right afterwards!)

last time i had that issue the crappy Bosch plugs i put in a couple of months before that burnt out i chased that problem for a month not thinking the plugs were bad being just replaced also a bad distributor bearing can cause the same issue or a burnt out cap and rotor

Could also be a vacuum leak or coolant temp sensor.
