Do you have a check engine light on? Have you done an engine control module fault code test (OBD2 control system), is fuel pressure OK under a load? Has the fuel injector spider manifold (inside the throttle bore) assembly been replaced, that is a known problem.

I have a 1999 Chevrolet Z24 Cavalier, It has 241,000 miles on it. It runs great and I haven't had to fix much on it. Just lately it started missing when you accelerate to speed up fast or go up a hill in...


Normally the first thing that would cause a miss like that (under load in a tall gear) is a secondary ignition miss, usually caused by a plug wire, or possibly a distributor cap or rotor-have these been replaced in the last 30,000 miles? If not, I would do them first. If it still happens, you might then change the fuel filter, clean the throttle body and Mass Air Flow sensor, and replace the air filter-that's a complete tuneup, it should last you another 50,000 plus miles as long as you change the oil religiously and don't overheat it.

When going up hills is the engine bucking and missing? Also for the hard start warm problem, check the fuel pressure regulator for leaks into the vac line.

Hesitation , skipping,engine cuts out when accelerating


Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?
