Default Computer Problems? REDUCED ENGINE POWER

Here is a short story: Sitting in a drive threw get a ding from the computer which says "REDUCED ENGINE POWER”, I look over my gauges to see that the temp is 260 Redlined. I park the car, let it sit for 30 minutes, still 260 redline, so I let it sit for 2 hours, still 260 redline before I even turn the key. So I decide to drive it home quick, get it home let it sit for 4 days as I went on a trip, come home don’t even turn it on just put it in the on position 260 redline, it’s also reading no fuel. It’s a brand new engine only had it for a few months. I’m guessing that the computer is going crazy or something. My question to you guys is this a common problem maybe with a quick fix =), or do I need some professional help with this one?

Thx CourTvette

I don't think I can help you much. I would start with the simple things that Corvettes are notorious for --- the two that come to mind are:

1. Battery --- is it OK?? Do you know for sure??
2. Check the grounds in the engine bay -- particularly since you said that the engine is new. Someone had the grounds all disassembled not to long ago.

This may not help at all -- if not I apologize, but they're easy to check and no cost. Take it from there ---

Beyond that, any DIC codes that you can share with the forum may get you more help.

Probably not your computer, and sounds like 2 unrelated problems, id first address the temp problem by replacing the temp sensor on teh drivers side head, its quick and easy should fix that problem.

There are a bunch of things that can cause the dash to go crazy. Some of the most common ones are:

1. Door wiring harness shorts.

2. Wet or damp BCM in the passengers foot well.

3. Shorted or grounded wiring harness. (related to#1)

The first thing that I would check would be the wiring harness for BOTH doors. Remove the rubber accordion tube, pull the harnesses out of the body and inspect the connectors and look for bare wires.





Check the passengers foot well for any signs of water check under the carpet and befind the seat.
