Hello my name is ***** ***** thank you for your question.

Do you have a Service Engine Soon light on when the car is running?

Customer: replied 1 year ago.
off the subject why does the oil dip stick have 90deg. bends
Expert:  Jay replied 1 year ago.

because there is no dipstick tube and the dipstick goes through the cylinder head.

I was going to ask if you know what your oil level looks like and if you know how to check it, cause it's tricky.

That shows how to check the oil level properly....

So let me know your oil level, and since you mentioned that the Service Engine Soon light is on when the car is running, do you happen to know what code you have?

I'm at work so I can't talk on the phone, I change my oil and do general maintenance. Would a faulty CTS or the Knock Sensor be the problem? I'm going to have the car checked for codes tonight after work
Expert:  Jay replied 1 year ago.

knock sensor won't cause this. I can keep this question open till you have the vehicle scanned. Once you have the codes, return back to this question and I will continue to help you..

sound good?

Customer: replied 1 year ago.
will do
Expert:  Jay replied 1 year ago.

Talk to you later this evening then.

Expert:  Jay replied 1 year ago.

Checking in to see if you were able to get the code?
