Unhappy What have I gotten myself into?

I bought a '92 VR4 a few weeks ago. The previous owner died in a boating accident in Florida so I didn't get a lot of info about the car, it has had a few mods. It was running nice but had some little "projects" for me to work on. The active aero wasn't working and the "Sport" light was flashing, and it badly needed a paint job, lots of cracked clear coat. The seller said it had sat in the Florida sun and baked.

Since it was running fine I went ahead and had it painted. The day before I take it to the body shop it suddenly starts misfiring. I went ahead with the paint job and had their mechanic change plugs and wires and filters.

Got the car back. Looks great. No improvement in the misfiring.

On the drive home from the body shop the gauge lights and the tail-lights go out, blown fuse. Replaced it and it blew again immediately.

The next morning the speedometer/odometer quit working, not sure why yet.

QUESTIONS:
What have I gotten myself into?

Is there any likelihood that the tail-light and speedometer issues were caused by the body shop or the tune-up?

What's my next step on the misfiring?

Could be a bad ground on one of the components. But this sounds like a power surge, you could look into the alternator what voltage/amps its charging with. Pretty easy check if you have a meter for that.

Is it always missing on one or more plugs? Check out the coils for that, pull off each individual plug wire and see if its arching. If not, you have a bad coil.

Could be cheap, could be expensive

Under the hood, the wires that lead to your windshield washers could be bad. Mine were frayed when I bought my 3000gt, and were causing the dash/tail light fuse to pop constantly. Try putting a larger fuse into it than the normal one, and look around for smoke. Once you've identified the problem area, then you can pop out the fuse/ unplug the battery to avoid further burning the wires.

1. Check fuses.
2. Advanced or AutoZone normally will test your alternator for free...not positive what the correct amps or volts it should be at but look around here and find out.
3. Ground Wires, I agree with Turbo Beast. My girl's car lost all gauge function because of a bad ground.

Bad advice. Never put a larger fuse in and look for smoke.

And if you had wires going to your washers then you had some ricetastic washers. There is no lights on the stockers.

If your ECS/sport light is flashing try unplugging your ECS computer. I know my car runs like shit with it plugged in since it is shot.

in addition to the wire issue,, i get the feeling your ECU may have some blown caps inside also. may need to send the ECU for repair.

Yeah, I was thinking ECU caps too. Check the alternator voltage, but I'm leaning ECU. Should be a fairly straightforward fix. keep us posted
