Keep the shiny side up & the rubber side down!
Hope some of you can help me out with this. Yesterday, I head out and get on the freeway shift to 6th, and BAM---check engine light! Car is running fine, call the dealer and head there. They hook up their code reader and find a P0420 code, cat inefficiency bank one. WTF!
I had previous problems with misfire codes when I ran Laguna but codes were P0300, P0301 and P2626. Short version, when I got back to Seattle, my dealer found that the O2 sensor wires were pinched and burned when they replaced the transmission!
This p0420 code is really surprising since I run Chevron 92 octane or Shell V-power 92 octane. Exhaust and airbox are stock, was using the silver key, and wasn't getting on it, shifted to 6th, on freeway with traffic.
Dealer cleared the codes, said it could be any number of things, moisture, bad gas, bad cat, (noticed soot on the left exhaust tip, none on the right) bank 1 is on the right. Suggested just driving it and see if it come back! WTF! So I take it out for a 15 mile drive as the dealer suggested, rush hour and traffic was bad, so I head home and thought I take it out today for a good long drive. Decided to check the oil when I get home.
On 4/3/13 had oil changed plus other fluids in prep for track season. Hadn't checked the oil when it was changed, but now I find oil is overfilled! Sent email to service manager. The owners manual states: Engine damage could occur from overfilling oil. Not sure I should be driving the car until oil level is adjusted. Car had 8671 miles when oil changed only has 8775 now after driving about 40+ miles yesterday, the day the P0420 code was thrown.
My question: Could the oil being overfilled throw this code? Is it safe to drive? I have no way of getting the excess oil out. Looks to be about a quart over. It's above the 2nd hole and almost to the writing on the dip stick above the second hole. I've never had problems with oil changes at the dealer and this is just careless.
Thoughts would be greatly appreciated. Of course it's the weekend so I won't hear from the service manager till Monday.
Could the soot on the tailpipe be from the overfill? Could this cause the P0420 code? Just not sure of what to do. Code wasn't thrown again on the drive after they cleard the code but now I'm not comfortable driving the car to see if the code will reappear.
What's the collective wisdom on this situation?
Cheers!
