CEL on after LOF

[not5-0]

just had oil changed and now CEL is on. I checked oil, dipstick and fuel cap and all good. Any idea what else to look for?

Tell us the code so we can give you an answer.

Did you perchance change the fuel filter too? That will give you a CEL.

Check the airbox and intake tract...did they check or change the air filter and not secure everything correctly? MAF plugged in?

The number will help us determine what is wrong.

Take it back and have them fix it

P0174 is the code

P0174 is the code

With that code, this is a good start. Along with a vacuum leak. Check PCV and vacuum hoses.

I'm going with they screwed up a vacuum line or yiur MAF is dirty.

Let us know the resolution.
