Misfiring


code p0303 refers to cyl 3 misfire detected ===causes engine mechanical fault--wiring--ignition/fuel system--injector--ECT/MAF sensor--ECM
code p0316 refers to misfire detected during start up --first 1000 revs===causes --engine mechanical fault--wiring--ignition/furl system--injector
the common fault cause is ignition/ fuel system and injectors so I would be checking fuel pressure and injector systems for clean and wiring connections are good especially on no 3 injector.

2002 Mits Galant has a hard time to start


Your P0340 is a different problem from your P0303, but they may be related.

Since the code P0340 indicates that there is something wrong with your cam speed sensor, your misfiring in cyl3 may be caused by this.

This points to addressing the P0340 error before the P0303 since it could be contributing to the 303 in the first place. Look at your cam speed sensor in cyl3 and maybe this would solve both problems at once.

Hope this helps.

Obd codes p0300 p0301 p0303 p0305 p0401


P0401 Exhaust Gas Recirculation Insufficient Flow Detected

P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0305 Cylinder 5 Misfire Detected


I would check out the EGR valve. That maybe what is causing all the misfires.
