My 1998 Ford F-150 v8 4.6L backfires on acceleration and is running rough. It has 175,000 miles and has never had a tune up. I am taking it to a mechanic and would like to know what to expect so I won't get ripped off. What is the approx cost of a tune up and what is it they should be checking?

If it has never been tuned up, chances are that is the problem. Has the check engine light come on? As far as a tune up, I would estimate around 200.00. However, that can change based on where you live and labor rates.

I assure you, if the plugs are OEM with 175K on them, they have been done for a long time. They will cause a miss and backfire.

Let me know if you have other questions.
