Is anyone from the area that knows of a reliable shop? My son picked up a 2001 F250 that he is having some misfire issues with.

 

I don't but hopefully some of our local members will.

We also have some pretty knowledgeable mechanics here in the forum. Post up some symptoms and some of these guys may be able to point you in the right direction.

Take care.

 

He bought the truck last week. 2001 F250 v10. Half hour test drive and 45 minute drive home were good. Started misfiring last weekend. He changed plugs since the PO didn't know when they were last changed. 92000 on the clock. He found 1 broken off COP bolt, and 1 broken COP ear. He swapped the "good" COP to the cylinder with the good bolt. Still can't extract the broken bolt, but has that COP secured in place. It has the rough running under 2000 rpm. His next steps are going to clean MAF, throttle body, and inspect for loose connections. COPs are a little pricey, so he purchased 1 to troubleshoot.

I think getting that broken bolt out is a must, just to get everything where it should be. He tried an extraction bit with no luck.

 

Sanderson garage in Swansboro!!!! Bout 20-30 mins from Jacksonville but is the only person I take my vehicles too! Give me a minute and I'll post his contact info, he is a ford man and good with gas engines and great with diesels.

 

Greg Sandersons is the owner/operator, and his wife Andrea works the office.

 

Thanks for the info 77mud. He ended up getting out of work late and didn't make it over there. Someone in his unit recommended another shop too and had a more thorough diagnostic ran on it which showed misfire on cylinders 2,4,8 & 10. The swapped COPs around and the codes stayed on the same cylinders. So they quoted him $1200 for new injectors.

 

I'd try new plugs before I spent $1200 on new injectors....

 

The first thing he did was change the plugs. Do you mean to change the plugs again on the misfiring cylinders?


He is going to try and run some injector cleaner through it to see if it helps.

 

Sounds like he's on the right track, checking and changing out spark plugs. I have a good spark tester that will test those COP's (Coil on Plug). If he could get his hands on one that could be less money that replacing those COP's.
Another thing that wouldn't hurt is a bottle of good injector cleaner. I like anything that is by Lucas.
I really wouldn't think that it needs every injector replaced. Somebody that is really good with a quality scan tool, could be a lot of help. There's so many different sensors and crap, a good diagnostic scan is the way to go.
Cleaning the MAF sensor like you mentioned sure couldn't hurt.
A wiggle test of vacuum lines and wires never hurt anybody either.

 

I missed the part about he had already changed plugs. I'd definitely run some Lucas fuel system cleaner, or some seafoam threw it.

If he gets a chance I'd be willing to bet Greg Sanderson would beat that price for the injectors and he had a very high dollar mac daddy laptop that monitors live data also.

 

He is going to try and get to Sanderson's this week.


He said that yesterday, it ran great (1st tank with Sea Foam). Then today (Sunday) rough again.

I thought fuel filter right away but that would have it misfiring on all, and not just the 4 cylinders.

 

Yea if it's not spark plugs or coil pack then it's about gotta be injectors.
