Has to be plugs right?

Miller335 · 11-09-2013, 02:40 PM

Bought car with 23K on it, put jb4 in it right away. At 27k now, have successfully ran about 4 tanks of E85 mix(about 30%) during all of that.

Lately I've noticed first cold start of the day it's not quite as smooth as it was when I first bought it but still smooth, runs map1 no issues.

Today I mixed in 30% of E85 and on the third 3rd gear pull it flashed the DTC and Check engine light very briefly and the JB4 defaulted to map4.

Codes are the following:
2A22 tankf nd, Korrelation
2AAD Fuel pump, plausibiity

Then there's the follow two codes but those are OK I believe:

2D25 manipulation cover, maxium air mass (I believe this to be the JB4 detection from DME)

2F6C Exhaust flap (I have it unplugged in the truck)

Should I see a misfire on a certain cylinder if it was the plugs?
Am I on the right track?

You should see a misfire on one or multiple cylinders. No code = no detectable misfire.

Misfires would have misfire codes, yes.
