Hi Scotty, Had a slow leak on passenger ft. tire. 6/26/24 Valve replaced and after driving for a day or so, all lights came on. drive 20 miles, lights go off, drive 20 miles lights go on. 7/1 One mechanic said perhaps purge valve. He did oil change and fixed exhaust tail pipe leak. 7/3 Took it to dealer he gave new gas cap, ran for 70 miles lights back on when I turned on the AC. Disappointed. Total spent is $300. Took it to nearby mechanic, hitched diagnosis up seems to point to emissions, maybe. Could it be the PV?, O2 sensors, abs sensor? AC never seemed to run right. When I turn it on it really pulls on engine and never seems optimum cooling. Maybe fuses, maybe spark plugs dont know where to start or who to trust. Ellen
After 2 months of this on going lights on lights off and new purge solenoid, one mechanic said Log it all. I did. I researched all the next steps of a PO441 problem and what I might need to fix problem; the list was long. I felt being emissions maybe Scotty's 505 CRF fuel system treatment might work and by golly Scotty it Worked!!
hitched diagnosis up seems to point to emissions, maybe.
What exactly does that mean? What were the actual results of the diagnostic scan?
@chucktobias Po441- Scotty's recommendation of 505 CRF Worked and resolved it all.
I have never seen the diagnosis scan. Now that the new gas cap was placed I drove longer with no lights coming on until I put the A/C on. Then all lights came on. Yesterday i get in car and Temp light is on with the same lights. I kept A/C off and all lights disappeared. So, Ill check A/C and air filters today.
