Question about 1988 Chevrolet Cavalier Z24
I have a 96 chev cavalier with the 2.4 engine, it suddenly went from normal to wont stay running. it sat for 3 days, started, ran for a short distance, then started to chug and not accelerate. it consistantly starts, runs up to 1500 rpms then slows to 4-500 rpms, chokes then dies
i have replaced ( at the suggestion of 'local experts') the EGR
(electronic, not vacuum) Throttle Pos Sensor, and PCM, nothing changed
it still started, ran great for 30-60 seconds then slows and dies
i was playing with vacuum line to the MAP when it started to run better, i replaced the vacuum line from the throttle body, to the inlet on the MAP
it ran 'normal' for a day, then right back to the same problem, i then replaced the MAP, nothing changed it starts, runs great for 30-60 sec then dies-
p.s. the fuel pressure was tested at 35-40lbs
Check the crankshaft position sensor. If the plug is loose or the sensor itself is bad it will cause similar problems
