accel, rev limit problem, rogue sensors

I posted when I bought the jeep, since then I have been working out the problems that I bought it with. I just got it on the road a few days ago, the rev limiter kicks on at 3.5 grand. The jeep is dirt slow and really rough in first. its a 1994 4.0L 5speed.

You can floor it all you want in 2nd 3rd 4th, 5th, it goes nowhere fast. I dont think ive actually gone faster than 45mph in it.

Being new to Wranglers I tried to see if it was stuck in 4L. The selector does move around and the 4WD light comes on at 4H and 4L. The transfer case did go into neutral and it disengaged. In both 4H and 2H the jeep has this issue. any clues what it is?

most likely unrelated I have two wires that I'm not sure where they go to:
this one is harnessed in with what appears to be going to the front parking light/blinker. it has a 20A inline fuse. there are aftermarket fog lights which both work. other than that theres an aftermarket head unit, no stereo amps in car.



the other is under the car, between the radiator and rusty oil pan.... right near the crank pulley. (there should be a red arrow in the pic)

My guess on the wire that goes to the parking lights - do the aftermarket fog lights only turn on if the park lights / head lights are on? Probably a trigger wire for their relay. My second set is triggered by the high beams (flash to pass = COOK in my Jeep!). Dunno on the other one, sorry.

Sounds like your timing is waay out. I'd check that - depending on miles, you could have jumped the timing set from wear.

Wish you were closer than NJ, I've got a scanner that could read your sensor data and see if anything's out of whack.

after inspecting some things I thought that second sensor was maybe the original fog lights, just tied out of the way. My fog lights are extremely bright, and I assume only for offroading. They come on by the original fog switch inside the jeep. they work fine, so the wire with the inline fuse appears may not be them.

it does have an aftermarket alarm that does not appear to be hooked up.

thanks for response
