Okay I had to repair my Hyundai 2004 XG350 three times at Quirk Hyundai in Bangor. All for the same problem: check engine. I had the following replaced/repaired: oxygen sensor, air filter, spark plugs, coil, and lube my brakes. Now the check engine light is on again, my car is shuttering, I am very very concerned. Almost two weeks after my visit at Quirk, for a whole week it is fine. Now it’s a mess! HELP!
That CEL (check engine light) is just a kid in class waving her hand trying to get you attention because she has the answer. You need to have the codes read. Some places will read them for FREE. Try Autozone or Advanced Auto Parts. Get the exact code (like P0123) not just their translation into English and post it back here.
The check engine light comes on for a multitude of reasons. Each time might be a different problem. Unless we know the trouble codes from the computer we can only guess what might be causing the light to come on.
Can you provide us with the codes?
First off, lubing your brakes won’t have anny affect on the Check Engine Light.
I seriously hope you didn’t pay for that as a solution to the problem.
Second, on your receipts from the Dealer that worked on your car, there should be a listing of what was wrong, and it might even tell you the codes that they pulled from your car.
Can you get those from us?
Your replaced parts so far don’t really have very much in common, but the codes might point us in the right direction.
