Fixed all the lights on the front, starting to work on the heater control valve.

got a new door check strap for the rear cargo door.

there is a e-clip that holds that pin and bushing together in the strap and on the hinge on the body. An e-clip that lmc wants to charge $18 for. What a rip-off.

Got her (many) codes scanned today. Good lord, I'm in for quite a ride with this thing.
P0340 - Camshaft Position Sensor (daunting)
P0141 - Sensor heater malfunction, Bank 1, Sensor 2 (typical)
P0122 - Throttle Position Sensor low input (Replace sensor?)
P0414 - EGR (ugh, can't I remove that?)
P1351 - ICM (Could be false code triggered by other problems)

What's funny is that even with all these trouble codes, she runs great until warmed up. lol.

it can happen but not always. sort of hard to explain but kinda how you exterior lighting acct weird when a ground is not right. but by all means if you you can probe or have a scan tool that can read like i have then you should be able to see what the reference outputs are pushing.
