Error code P0301 - next steps...
Pulled the codes off today thanks to pubsinger - really helpful guy nearby who offered to help from a previous thread, and got P0300 and P0301, so misfire on cylinder one. I already suspected this was the problem for my lack of power/misfire/hesitation below 3000rpm that tends to clear up after 15 mins or so once warmed up. I was looking for some help with what the logical steps would be to get to the root of the problem - so far:
- All spark plugs changed 20,000miles ago
- Cleaned up spark wells and coil packs (Oil in 1 + 2)
- Unplugged MAF but not change and the problem is low down in revs (over 3000 rpm no problems)
- New air filter and no sign of any leaks in pipes all the way to throttle body.
I have seen that lambada's, injectors, coilpacks, cats etc... etc.. can be cause so was looking for some help on a logical process to help get to the offending item?
I'm not a mechanic but have been learning every step of the way of my 4 year 'alfralationship' so would really apprieciate any help to get the bottom of this current issue.
