Engine Mechanical problem
2000 Volvo S80 6 cyl Front Wheel Drive Automatic 83000 miles
We recently drove thru some heavy rain and large puddles on the highway. One week later the car was ilding roughly and when you press on the gas, the RPM's only goes as high as 2000. That's in drive or in park. The on board computer had three message's. 1. ABS warning 2. STC warning and 3. Engine system warning. We let the car sit for a week. The only warning now is the Engine system warning. The engine acts the same way as a week ago. I know I will probably have to bring it to the dealer, but I want to go in there with some knowledge about the problem.
Thank you! Please Help!
