. . . Has anyone has similar experience with CEL.
Yep. While driving home the CEL came on and I pulled over and checked the manual and it said to drive the car to the nearest dealer. Was only 6 miles from home and over 45 miles to the dealership so I opted to drive it home. Called and they advised me to have it towed in, (Which I did.)
, and while I waited for a tow I checked the engine with a code reader and got the now infamous P0420 code. Each time I started the car the CEL came on, and when the tow truck driver, (Actually a truck with a flat bed trailer showed up.)
, as I was driving the car onto the trailer the light went out.
After having the problem diagnosed at the dealership, they had us pick the car up and drive it since it was going to take about a month to get the new catalytic converters in. After about 700 miles the CEL came back on again and since we were close to the dealership we took it in and luckily they had the replacement cats in stock and were able to fix it over the next few days.
Everything was fine for a few more weeks till the light came back on again, but this time it flashed about three times, went back off and was diagnosed as a whole different situation . . . and a lot worse then the previous problem. (But that's a topic we can save for a later time!)
Let us know when the light comes back on and you finally have to have the cats replaced!!
