My truck is running rich. I was told it could be my air flow mass sensor or a bad injector. Has anyone had this problem before and if it is my injector how can I check it.

 

The injector issue was on a handful of 2005's. What year is your truck? Start with cleaning the MAF and go from there.

 

My truck is an 06 5.4

 

Probably past the injector issues then (of course there's always that one random one), but start with the MAF. Is the rich code on one bank or both?

 

It is on one bank. How would I go about cleaning the amf sensor?

 

Sorry typo. How would I go about cleaning my air flow mass sensor. What do I use

 

Only one bank would make me think injector or misfire, but still clean the MAF. It's really easy, go get some MAF cleaner and locate the MAF in the intake. Give it few good shots and don't touch it, that's all there is to it.

 

Ok cool. Thanks for the help.

 

Injector problems were in 06 I believe. But if 1 had an issue it would run rough.

 

It takes a few seconds to start the truck but once running it runs fine. The only thing is you can smell the gas. The truck runs rich.
