So my Jetta is acting up has had a CEL for a while but i was never told due to me being deployed and the person driving my car didn't care. So I plugged the 'ol OBD2 reader into it and it throws these codes:
P0300 Randon Misfire Detected
P0301 Cyl. 1 Misfire
P0305 Cyl. 5 Misfire
P1237 Cyl. 1...
My check engine light came back on today and these are the codes I got:
Can anyone tell me why cylinder 2 isnt included.?
P0420 is this causing all of the other problems?
Where do I start?
I've already bought a fuel pump and filter.
