Are you running any tunes? Your not getting enough air? If cleaning the MAP sensor and the air filter does not change things, let us know?

I went ahead and made an appointment for monday morning, just bought the truck 3 weeks ago. There were two other codes on it other than the MAF codes so if I learn anything on Monday I will fill you in. I thought for sure it was the K&N clogging the MAF... Sorry

D. racer, You said you had no codes. Just out of curiosity... Who checked it for you? The reason I ask is I took mine to the auto parts store where they checked it with a tiny handheld and came up with nothing. So I went to a shop next door where they had a much more elaborate set up and found four codes as follows:
P2610 Control Module Igntion Off Timer Performance
P0101 Mass air flow sensor performance
P102 Mass air flow sensor circuit low voltage
P0540 Intake heater feed back circuit
I cleaned the MAF last night and got a little better, I'm going to get it rechecked and see if the MAF code is still there.

No Idea
I have no idea? I guess it was the MAF. I put in some fuel catalyst, filled the tank and just putted around town on a bunch of short trips, nothing over 30. By Sunday night I really had to try to get it to smoke. Brought it in Monday and they cleared the codes and re set the check engine light. Charged me $100 and said it was the MAF? Put 2000 miles on it this week and seems to be doing just fine...

I was going to just replace it but it was a factory direct order that would have taken 3 days to get and it was not a $10 part. I think it was around $200 with the core, so I opted to just let the dealer look at it first before I started replacing stuff. Thanks for the input everyone, you have all been more than helpful. Looking forward to my next panic when something goes wrong...
