Hey guys, For some reason my RPM gage on my automatic 92 vertible gt, is stuck on 4k. engine idles fine, revs fine, but is stuck on 4k. I have recently been downshifting alot, dont know if this has anyhting to do with it being stuck on 4k. when the car is off the needle on the gage returns to 0 rpms, and if the engine is off but ignition on the needle is on 2k, when I start the engine it goes to 4k, but the engine revs normal. when I step on it it barely moves up. any ideas? tks guys.
