First V- 10 issue .....

[Tom Foley]

Van went in for induction service and fuel filter change came out running like crap . new plugs were added to no avail . Not showing codes so now I'm thinking clogged injector form the sludge , I mean sludge that came out of the filter .
Any ideas I can relate to the shop would help . Thanks . 727-457-8253:thumbsup:

New fuel filter will make pump scream to recharge system .. Kinda like over rev on whooped motor when pump has 90+k

exactly, see it all the time, also could be carbon deposits unseating valves since induction cleaning. Tom boating in the gulf today??!!! You are crazy:eek:

It's a wild shot but could be a plug gap issue.

What plugs did they use? I had an issue like tis on my V-6 mustang. Ran like crap with Autolite's, put the stock motorcraft plug back in and problem solved.

[Tom Foley]

It did it before the plugs were put in . From what i have gathered over the weekend the IAC valve seems like a likely possibility , we'll see today !!

Tom, it shouldn't be a big deal for them to unplug each coil to isolate the problem cylinder. Then, using a labscope (if their tech is worth a chit) he can watch the firing pattern of the coil to make sure it is firing correctly, that will also show if the cylinder is running lean/rich based on the firing line. If the coil firing looks ok, they can also use the labscope and a low amp probe to monitor the injector current to make sure it is opening correctly and for the correct time. Being that it was running fine, you dropped it off, and now it runs like chit, I would say either a coil pack failed or the induction cleaning unseated something that tried to pass through the engine and didn't make it through........or they did something really stupid and left a vacuum line off or knocked off a harness connector somewhere. It shouldn't be rocket science to figure out what happened. Remember a Ford may not set a check engine light or log codes right away for a misfire. Sometimes it will take MULTIPLE drive cycles to set anything. If they haven't figured it out yet, I'd at least have them trace down the affected cylinder then it should be a process of elimination.

I just changed out the coils on my F150 4X4 since it had 130K Miles and would stutter every time it went through the car wash. It purrs smoothly now. I got the coils off Ebay [8] for about $100. The only hard part is removing the injector rail to get to the coils under it. I put the OEM Bosch Platnum plugs back in it.
