hello yall. my wife has a 93 vert that is having a wierd problem. ive never had a car that has done this before. When she accelerates the car lacks power and once the car reaches 55 or 65 or whatever...final cruising speed does not matter...the rpm's are off. by that i mean that the tach seems to be registering to low an rpm. at 55 or so its only showing like 1500 rpm. shouldnt it be some where around 2000 or so. also this all started after her check engine light came on. right after the car did this the first time the rpms suddenly jumped back up to where they were supposed to be and the car accelerated like it should, then just as quick it went back down again and has never been right since then. anybody have any ideas what our problem is. id appreciate any help you could offer. thanx in advance.

I had the same problem, take the one you got back and get a new one. Somtimes it takes a couple of trys. And be sure to unplug the battery before you replace it.

and make sure you put dielectric grease on the back of it when you mount it.
