Well on the way home from picking up metal for a project, my check engine light came back on
About 15 minutes later(about a mile down a dirt "road") my ABS/Stabilitrak lights came back on....
Hooked up the scanner when I got back and had P0171.... again. And C0035....again
Started with the Wheel Speed Sensor code, last time I had the code it ended up being a bad connection. This time the plastic retaining clip had broke and the sensor wire rubbed against the tire eventually wearing through. Put one of my spare wheel bearings in and put a zip tie around the clip for added security.
Since my plugs are new, MAF and throttle body were just cleaned, my mind instantly went to secondary air valve...
But since P0171 was what popped up right away, I didn't check for any other or stored codes. Sure enough there was a cyl 6 misfire.
Pulled the PCM bracket off and started tightening intake manifold bolts, they were all loose. But once I got to the back... roughly 2 turns backwards and the bolts were in my hand
So I'm glad I found it when I did. Hoping that that was the cause of the P0171 and not the secondary air BS (pretty sure it was since the bolts were loose around cyl 6 and that's the misfire I had)
