Scanned twice, different codes.
Well, I've had my SSE scanned more than once for codes. Probably a total of 5 or 6 times in a little over 1 month of ownership. Anyhow, in all those scannings I've had codes. Whether there was 1, 2, 3, or 8, the only one'* that are the same are P0171 (front Bank lean -#1 o2 sensor) and P1811 (Maximum Adapt and Long shift -Purge Canister solenoid).
I only scanned once since I did a soaking of my TB with Sea Foam Deep Creep. I don't think I let it soak/dry long enough as I had to leave for an appointment about 7-8 minutes after spraying 3/4 of the can in. I'm wondering if this is the cause for the MAP codes. I changed the plugs and o2 sensor a couple days later so I don't think this would be the cause for the lean condition.
The other codes from the BIG PULL are (including above stated):
MAF or VAF
Curcuit Low Input
(Did my Deep Creep do this?)
Curcuit High Input
Curcuit Low Input
(I intend to pull the TPS for the TPS mod -hopefully this helps, if not I'll be needing a new TPS -got a part # for GMPD?)
System Too Lean
(I've replaced the sensor with a new AC/Delco AFS 109, disconnected the battery for 1 hour and the code still persists -switched new plugs in at the same time TR55'* gapped at .057" -is this gap too small causing the lean condition?)
Trans Range Sensor
(My shifter is a little sloppy, and I don't need to pull the button to go from D-3 -it pretty sloppy from R-N-D-3)
Maximum Adapt and Long Shift
Seems like when I pull up to a stoplight or stop sign when I take off I get a bit of jerking -2 or three jerks- like it'* doing the quick hard downshifts from 3-2-1 too late, but if I pull the shifter down into first while it'* doing this it stops right away -is this related to the Trans Range sensor?
Thanks for any help.
I hope to get this stuff straightened out before I do any more mods. Hopefully, before I send the PCM into Intense -don't want to send it in and find the PCM is a bad one.
I'm going to reset the PCM tonight and see if I can find someone in Alexandria to scan it tommorrow. I'm hoping it'* my PCM so I don't have to change 10 different items. Besides a good junkyard PCM (with warranty) is only $35.
