P1170 P117B Direct Injection Issue?
EDIT: Thread title is wrong. I believe the codes were 0171 too lean and 117B direct injection. NOT 1170 port injection.
I have had oft headers and e85 for almost a year now. Today car threw check engine codes P1170 P117B. I reset the codes, and I did a wot pull from 3k to 4.5k and the afr was good, mid 12s, and LT trim was around 7%, but then adv mult dropped to 0.0. Ignition adv is in the 40s. I recorded it and will post the log soon. I'm going to make another log on the way home. Which parameters should I be logging? Should I try another wot pull? Any ideas? The car sounds and idles fine. Thanks a lot for any help. Cross posted to Software board. Last edited by gonzo; 02-11-2015 at 09:38 PM. Reason: Wrong thread title |

P1171/P117B: After speaking to my mechanic, he mentioned that i'ts a intermittent failure of the high pressure fuel pump. I bought some Lucas injector cleaner, just to be on the safe side. I guess it's just a waiting game until it fails. that is, if it's even that. It could be leaks in the intake, or exhaust too. Will keep y'all posted, but it hasn't returned since I disconnected the + from the batt and let it sit for a half hour.
