Hey guys, new guy here.
I just acquired a 98 Viper GTS (King Snake) that's had a ton of work done to it over the years, so I know this may be a difficult one to answer definitively, but I'm just looking for some ideas of things to look for.
Weird things that are happening:
- Speedometer is fluctuating around 40 mph at idle (and yes that means odometer is ticking up!). When the car is moving, it seems to be working fine.
- The left turn signal (dash light) is faintly lit.
- After the car heated up, the shift light came on and stayed on (aftermarket, obviously).
- The oil light came on.
- The car will not idle until it's warmed up (this may or may not be related).
This has an aftermarket AEM ECU, but also still has the factory computer. That means there's extra wiring everywhere, so I have a lot to sort through. This car has been sitting for a while, but when I bought it a week ago, everything seemed to be normal.
My initial thought was that it's a low power, or high amp draw, issue (if you've been in a car that almost completely loses electrical power, everything just goes haywire). But it could also be a wire that rattled loose, or was mostly chewed in half by a mouse.
A ton of variables, I know, but if anyone has any experience with something like this and might have a few pointers on where to start, I'd really appreciate it!
Also, yes I cross-posted this on "another" forum.
