1990 Buick Regal 3.1 has rough idle, hesitates and dies when accelerating.


A lot of new parts! Have a compression test done to gauge the engine's internal condition, and go from there. If compression is good on all 6 cylinders, scan for trouble codes. The compression test may find your problem, something like an exhaust valve burned or not seating properly.

It's located under the hood, nestled sight under the firewall, and on top of the exhaust manifold.
It looks like the picture below and has four wires extending from its top.

Need to know the location of cam sensor on 1990 buick regal


It's just under the water pump. You most likley need to replace the magnet that is on the cam gear to fix it. The sensors hardly ever go bad. The timing cover will need to be removed to fix the magnet.

Don't know what type of sensor I need for my 93 Regal


If your check engine light is on the computer in your car can give a code. Aamco will read your check engine light for free. Might need a repair manual to find out what code means (which o2 sensor). If check engine light is not on you will probably need to get each o2 sensor tested by a mechanic.
