lives in Columbia, MO and just purchased this car for his wife from a dealer in Houston; he posted in the New Members forum. Let's cut him some slack and help him out, OK?
- Did you buy the car new or used? IIRC, you just bought the car for your wife, and the dealer in Houston is where you bought it from.
- If used, was the car CPO (Certified Pre-Owned) by the dealer?
- Does the car have a manual transmission or an automatic transmission?
- Who has driven the car regularly since you purchased it? Sounds like only your son and daughter? Are they both proficient with driving a manual-transmission car?
I know this next thing is hard for a father to do with offspring that he trusts, but you need honesty regarding how your daughter (and, to a lesser extent, your son) have driven the car. If there were a lot of over-revs on that engine before it was sold to you, it would not have passed the CPO certification process unless the dealer itself is fudging that process -- which means the over-revs occurred after that certification.
I would have the Tulsa dealer verify that the over-revs are on the car's ECU -- it's operational computer, if you will. If possible (not sure the ECU logs this), but have the Tulsa dealer note dates of occurrence of the over-revs. That bit of data will be telling regarding who caused the issue.
Good luck, and keep us up to date.
