I took the car to autozone and got a code po304.my car will not start unless i push it then pop the clutch. on the way there it was running fine when I got to autozone it cut off so i had to push start again. it cut off while i was slowing down and when i stop. the code said cylinder #4 misfire. Causes are: spark plugs, ignition wires, coil, vacuum leak, injector fault, high or low fuel pressure. I changed the plugs and wires. didn't help what should I do next?
Cylinder 4 misfire ,now if this is a GM product then i think you may need a reconditioned ECU init as if this is the 4 cyl engine and its same as the opel astra and zafiro and the vectra then its a common fault with a 2000 to 2004/5 model the computer is bolted to the engine inlet manifold and very weak and susceptable
