Any vac leaks or chance of a dirty MAF?

 

[Stevejr]

No vac leaks that i can find shouldnt be dirty I just put on on a month ago.

 

[HISSIN50]

What other causes can you think of for runnng lean on both banks?

 

[desertcox05]

are you running a k&n style air filter. the oil can come from those filters and deposit on the maf.

 

[Stevejr]

Yes I am runnin a k&n filter, so i need to clean maf again. There were 4 codes are they all related to this lean condition? Thanks.

 

[Stevejr]

It doesnt idle well either. Any ideas.

 

[HISSIN50]

A vac leak can cause a crappy or wandering idle. Keep looking for leaks. If you use a vac gauge, you should see almost 20" hg on the gauge.

Vac leaks relate to a lean condition as well.

Im gonna clean maf tomorrow and check for vac leaks, car is not as strong as it was either. Thanks for the inputs.
