1990 Chevrolet Corsica Q&A
1990 Chevrolet Corsica Question: Where is the fuel pressure regulator located on a 1990 2.2 4cyl ?
Car runs good most of the time , but has got to where it will run like it is on one cylinder, I have replaced the plugs,wires, coil packs, computer, fuel filter and it still does it, As long as I baby it ,It will run okay, but if I drive it normal it will run like it is choking, I have also removed the converter. Not sure what to do? - tbone843
Where the pressure regulator is not relevant. What is the running fuel pressure and volume? Is the check engine light on? You need to be able to view the serial data with a scan tool not a code reader. You could have a bad O2 sensor. - PARTS GUY
