I have a 2005 Mountaineer with a 4.0l V6 and AWD with 59000 miles. In the past 6 months I have noticed that whenever I am on the highway the transmission (or engine) will hesitate (hiccup as my wife calls it) between 1000 and 2500 rpms. The dealer said the computer showed misfires in the lower rpms so I should replace the plugs and wires. I also changed the fuel filter. Well after $350 the problem is still there. I think it has something to do with the transmission.

Any ideas?

Thanks

Did you tell the dealer it was still doing it? There could be a coil problem causing the misfire.

I did tell them. I even waited until it was doing it and went to the dealership and took a mechanic for a ride so that he could experience it. They told me the plugs and wires should be changed, along with a laundry list of other things that were mostly related to the scheduled maintenance stuff that they recommend at 60,000 miles, including an oil change. I do my own oil changes and had just done one a week or so before. I took it to a local mechanic and he really couldn't diagnose the problem. I had him change the plugs and wires and the fuel filter. I really think that dealers want to do all the non-warranty work first. I did buy the FORD extended warranty that still has 15,000 miles left. I can replace parts and at a much lower hourly rate.

Check the codes. Autozone will for free. That will help. The mechanic that did the work should give some help too unless all you had him do was what you instructed him to do.

I'll try to stop at autozone and see if they find anything. But if it is a transmission problem, will there be an error code?

I stopped at Autozone and asked about reading error codes. They said they could only read the codes if the "CheckEngine" light was on. Any other ideas?
