Hey guys, I haven't been on here for a while but I thought I would toss a question out here. I know I'm not the only one who has the stuttering v6 problem. every now and then the idle will start getting rough and it has died at a few stoplights. It was horrible in the summer of 2000, the truck would shake and die all the time. it's better now and the stalling incidents are getting farther apart.
I'm doing some reading and I have always wondered if the fuel system was to blame. Has anybody actually replaced the fuel pump or any of the fuel regulation system?
The catalytic converters stink as well, and I was reading that a rich fuel mixture can cause that. Can a rich fuel mixture cause a inconsistent idle?
I might take it up somewhere to get a computer diagnostic done, but I'm not taking it to the ford dealer here, b/c they don't have a clue as to what is going on.

anybody have any thoughts on this? Has anybody messed with the fuel mixture?

 

Hello,

From my experience with EEC-IV and EEC-V, the condition you mentioned comes from either air reversion (turbulent air from under the hood- fan wash most notably- blowing on an open filter element at varying speeds and temperatures within a small amount of time) or unmetered air entering the intake stream (a vacuum leak). The ENTIRE world depends on no vacuum leaks and as little air turbulence as possible just before the MAF sensor.

It could also be linked to the plug wires (not Ohm matched) or a plug on the edge of fouling.

As far as fuel system components go- they're a snap if you end up having to replace something.


Later,

if you have to much feul press its not the pump. its going to be the regulator on the fuel rail on the engine. but like wrongdayj said. there are a lot of things on the engine that could do that. you should have a check engine light doing back flips. so there should be some codes. good luck
