P0303 Cylinder 3 Misfire
I have had the P0303 cylinder 3 misfire code for at least six months. We
repaired the smaller things such as the fuel injector and spark plugs. The car
shakes and runs rough, the check engine light has been on. At times, I hear
rattling (could be catalytic converter). There was also times where my car
has died out on me while accelerating (we replaced the battery). I had a
cylinder compression test done and cylinder 3 is at 60 when it is supposed to
be at 120. Currently, my check engine light has been flashing rather than
staying intermittent. The light will flash until I start driving the vehicle and
then will become intermittent again. I am assuming that this is the catalytic
converter and that it is damaged. Could a bad catalytic converter be the
reason or be related to why I have such poor pressure in cylinder 3, or
should I not get my hopes up and prepare to replace the engine/find a new
vehicle?
