Oh codes... I got 'em!!
P0171 - Fuel Trim System Lean.
I have an intermittent P0171 code... only comes on once in a while... maybe once a week. I changed the O2 sensor and it still senses it. I suspect it's something to do with the ported head, Quad 4 LO exhaust cam, oversize valves and the 62mm throttle body... but I have no real idea yet. I probably need larger injectors or a bigger fuel pump or an adjustable FPR that rises with boost, since I've done lots of "air" mods but no fuel mods... Maybe one day Adam and I will check it out
but I'm not terribly worried about it. At least not until I solve the others...
B2662 - Park Lamp Switch Circuit Malfunction
I think this might be a result of my DRL kill mod...? This DTC *can* set when the lowbeam or highbeam inputs are on, but the parklamps aren't. Not worried about this one at all.
B2707 - Gearshift Unlock Circuit Low
This is left over from when the car was an automatic... since the BCM is the same (same mileage). If I can find a BCM on a wrecked 5 speed with keyless entry, A/C and similar mileage, I'll swap it... but until then, I get the T/C Off light stuck on. Oh well.
B0051 - Deployment Commanded
Oops
This is from my airbags. I bought a 2000 Sensing & Diagnosing Module (SDM) from Ebay... was told it was good... guess it's not
Thus, the airbag light stays on. At least the bags didn't blow up when I put the fuse on
U1000 - Class 2 Communication Malfunction
I suspect this is related to the SDM being blown. It sets the Service Engine Soon light, and it won't shut off... so I'm going to go with that. Once I replace the SDM, I'll know for sure.
Ahhh, good times....

Damn, that's a lot of codes.. How's the car run?
