Hey y'all,
I usually don't have many questions because I can just search, read and find the answers to my questions. But for some reason the SEARCH feature wasn't cooperating with me.
A week or so ago, when it was really cold out, I let the truck warm up for a minute. When I came out, the CEL was flashing. When I had first started the truck, it was running a little rough. However, warmed up it was idling fine. So I thought it was a misfire. I drove to work without incident. Came home from work and no CEL.
I have an OBD2 scan tool. I plugged it in and was getting a strange message basically saying I wasn't connected. I put new batteries in the scan tool, still nothing. I thought my scan tool may have gone bad.
Last night, my wifes car threw a code. I tried the same scan tool. Worked! Code P0442. WHEW... only the gas cap.
I tried my Avy again... still no connection. Ruh roh.
Fortunately, I haven't had any more CELs on the Avy.
**SUMMARY**
-- '03 Avy flashes CEL on cold morning
-- Scan tool fails to connect to Avy
-- Scan tool connects successfully to wife's car.
Thanks for any help or ideas.
