How do you install a tachometer on a 1991 Cavalier Z24 multiport with electronic injection?
As far as what tachs will work: buy a tach that has what is called an "inductive" pickup. this is a clip that you put around a spark plug wire, it will give your tach the signal it needs from the engine. the rest of the basic instructions, even though they wont be for your exact car, will be in the package with the tach.
The 3100 SFI engines were rated to 160HP, like the 3300 engines were. The 3.1 MultiPort FI were rated at 140HP. Of course, you certainly can swap a 3.1 MPFI engine in your Century, and in my opinion, you would do a very good choice. If a 3.1 MPFI can work in a Chevrolet Cavalier, why wouldn't it work in a Century?
If instead of the pickup on the tachometer of a Chevy Cavalier you have a green wire where do you put the wire?
Why does my 92 Cavalier with auto transmission run in park but when placed in drive or reverse it stalls It has to start in neuteral then shifted in to drive or reverse so it can run without stalling?
You changed plugs and wires and the problem is still there? Well assuming you did that already, My 91 cavalier did the same thing. It turend out to be the electronic ignition control module on the back of the motor. 20 bucks from a junk yard. Mine went a 240,000 miles. I just answerd how to change that to another person on here.
