Check Engine Light

[MarcInJapan]

Just my luck, 2 days owning the car and the check engine light comes on. It was after I detailed the motor, so don't know if that had anything to do with it. I didn't spray it with water or anything like that, just cleaned the hoses and metal. The car seems to run fine with no issues. I left the Battery disconnected overnight to clear the memory, but after the second start up, it came back on again. Maybe a bad oxygen sensor or something like that? I wish I know how to code it like I did my mustang. So many beeps or light flickers on the dash, and I would know what sensor was bad. I guess I will have to take it to the dealer where they will charge me a arm and a leg just to hook it up to a diagnostic machine.

Any suggestions of what it might be? Again the car runs great. The light is annoying as hell and I don't want to drive it too much just in case it might be something serious.

I stand corrected, not it won't idle worth a damn when I am stopped. Sounds like a bad sensor or something.

I would bet for a dead lambda sensor if you still have the cats on the exhaust. You should have the error code read via the OBD II to be sure, any garage has a reader.

Thanks. It still has the stock exhuast. Hopefully that sensor doesn't cost a lot of freaking money.

Check to see if you disconnected any wires or pipes while you were detailing the engine...

Too much of a coincidence, and could save you a fair bit of money.

Just like I thought. Turned out to be a oxygen sensor. The guy before me used to use 104+ octane every time he filled up. I know that was the cause of it over time. Runs like a champ now!

the lambda sensor cost about £100 at the dealer

Car runs great now! Like a new ride! :)
