Okay, I used this link here: http://www.lexls.com/tutorials/intro/codereading.html.
I was able to get ahold of a code for an Engine fault but was surprised to find that the Trac system was reporting no faults at all. The engine fault code that came on was 25 - Lean fuel mix. I found another post on this forum that talked about it a bit and decided to get some SeaFoam to see if maybe the engine needed a bit of cleaning. Then I went out and drove it around to heat the engine up a bit... :).
Now, after the drive, the Trac light in the Tac will come on a bit of a ways into a long drive and stay on. (Is that a good thing? Is it supposed to be on or off?) The car does seem to have pepped up a bit since I put in the SeaFoam. Though, to be fair, that could be a placebo effect...
Oh, I also checked my air filter and found that it is old and has holes in it (I just bought the car, not my fault...). I'll be replacing it tomorrow first thing. (Which reminds me, the car looks like it wasn't terribly well cared for, any other maintenance I should be running on the car at 109,000 miles that may have been skipped? I know the oil is clean and everything that is easy to see looks good, what about internals though?)
The Check Engine light and the Trac Off light remain on. I tried to follow the instructions on the other post to turn them off but couldn't find the fuse, I think my car model might be different. Where is that fuse to clear the warnings on a 1992 SC400?
Oh, while I was getting the Engine Fault Code the O/D light was blinking like mad continuously. Is that supposed to happen or should I be worried?
Sorry for the confusing post, there are a few things happening at the same time... Thanks for the help so far!
PS - Any idea where I can find a repair manual for this thing? I can't seem to find one anywhere...
