Lately my car has been doing weird things. Actually for the last 6 months and seems to be getting worse.car won't shift right. Car sounds different. Loss of power. Today when I turned the key once nothing was displayed on the cluster? Cluster not displaying at all now. The otherday I tured off the car and the rpm was jumping up and down to 1rpm. Think the computer might be messed up?

 

Could be the wiring harness on the transmission. One of the wires might have a break in it. As for the cluster, I don't the problem is the cluster so I would check the wires going to it. If the wires aren't bad, then I would guess the problem would lie in the ECU. I am not a professional and I am not there to diagnose the problems, so this could be way off. So therefore I would take it to a professional. ZZP, a stealership, or something of the such.

 

PCM or bcm acting up or going bad. Could be a ton of things man. Check all your grounds as well. Or you could just simply need a new throttle body as that controls a lot. I'd say try replacing the throttle body and checking your grounds

Mods?
