Misfire gone, but now 2aaf and 30ff

Gmanuel · 08-01-2014, 06:40 AM

Hey guys, to give some background, I filled up with about 5 gals e85 and the rest shell 93 last week with the intention of trying the e30 map from Cobb but when I did a pull, I got a misfire on cylinder 1. After that, I eventually backed it down to Stage 2+ Drive (misfired on aggressive and sport).
Today I finally got around to swapping the coil from cylinder 1 over to cylinder 2. I bumped the map up to Aggressive and drove the car around for a while so it could adapt. I did a pull and instead of a misfire, I got 2aaf and 30ff. The car was pulling pretty hard and seemed fine. I started off at about 3k in 3rd and half engine light came on at around 5k in 4th. Any ideas? I know what the codes mean, but could the combination of the three (29cd, 2aaf, 30ff) point to a specific piece of hardware?

Anyone? lol here is a log from today that didn't throw any codes. I wasn't able to get a log of the one with 2aaf and 30ff. http://www.datazap.me/u/gmanuel/stag...og=0&data=1-21 Any ideas would be greatly appreciated.

2aaf is fuel pump plausibility. Everyone gets that so you can ignore. The 30ff is a leak somewhere. If I had to guess you have stock diverted valves?

Okay cool, I was getting paranoid since all the threads I saw seemed to be saying that if 2aaf is accompanied by other fueling codes or even misfire codes, it could indicate a problem. Yeah, stock dv's; would Forge dv's be a good solution if the stock ones turn out to be the culprit?

Reason: Mixed up 29dc and 29cd. It was cylinder 1 misfire.
