Trouble codes
I did the old paper clip trick which flashed me 2 codes.
34: MAP sensor signal voltage was too low (high vacuum) when engine speed was under 600 RPM or the engine speed was over 600 RPM with a throttle position angle above 6%.
MAP= manifold air pressure, right? So then what wouild happen?
And code 12...which I cannnot find an expalnation on.
Here is a pic of my ignition coil. It's a bit hard to see but there is a break in white wire--not broken but uninuslated.
Where does this wire go?
(for that matter---where do all 4 go?)
Can I try to tape this up? Or where can I get a replacement wire?
Sorry , I am real noob

Re: Trouble codes
Well I will swap the MAF and MAF burn off relays (I think that makes sense) and go for a drive. Maybe thats the problem, I hope.

Re: Trouble codes
code 12 is the code telling you that teh computer is in diagnostic mode. all codes following that one are trouble codes. and dont just throw parts at it cause your just gonna waste money.
