Blower motor will not stop after engine is turned off. Is this a relay switch issue? Motor will run at very high speed. After a few minutes it would intermittently turn on and off. Battery was discharged two days ago. I forget how to test these relay switch, been a while since I’ve used my old DMM. Anyway, I’ve got an error code PO4091 (secondary air inj sys insufficient flow, bank 1). I lost the info on the two other error codes, but I will dig it up later and see if at all related. Any help on this would be great.
Off topic. Found a vacuum line broken, reinserted the remainder of the tubing, so good for now on that end. It’s by the TEE next to the battery. No wonder this one was stalling around 600 RPM and on low speeds around 600 RPM.
New coils wires and spark plugs. Runs smoother now.
