My car has a tad over 36k. I was getting a rough idle at times, usually after the car was good and warm. Nothing bad but noticeable. I would also get hesitation from time to time, like when passing. Another thing I noticed was that my AFR was settling more towards 14.5 rather than 14.6/7. My car also felt like when I went WOT that after 50% peddle the car felt like it was bogging down like it was getting too much fuel. It's hard to describe but that is how it felt. 50% peddle felt better than 100%, if that makes sense.
On my DashHawk logs I noticed my AFR's when WOT on a custom map from Christian was 11.5ish and I wanted more along 12.0ish.
So yesterday I was tinkering with my car and I decided to check my MAF. The filter side of it was BLACK the backside was a deep red it looked like. So I whipped out the can of MAF cleaner I had and hit it with about 30 squirts all around (didn't touch it with anything) and let it dry.
I took my car for a spin today to get some more maps for Chrisitian and my tune. OMG - My car has not ever ran this good. My AFR's were back to 14.6/7, my idle appears perfect, at least I didn't feel the rough idle like I have before but will still give this a few days to verify it is gone.
The power is the big thing I noticed. On this same map, before I could take off and spin 1st and a tad in 2nd and chirp 3rd pretty good. Today I started a pull in a rolling 2nd around 3500RPM's. When I floored it she instantly spun like crazy and didn't stop until I let off a bit and shifted to 3rd.
I then decided to do a log from a stop to see how much she would spin. I spun the entire 1st and 2nd and half of 3rd gear! I then got a bark from 4th! Also the bogging down was gone. The more I mashed the better it felt and 100% felt stronger than 50% again. The change was just amazing.
So when I got home I looked at my logs. Were I was at 11.5ish before I was now at 12.3 to 11.9ish. My FP was also a LOT better on stock internals sitting at 1600-1700 with only one small dip to 1375 after a shift from 2nd to 3rd but immediately back to 1600+ after.
So from this point on I will clean my MAF every oil change. I didn't think it would make this much of a difference, but WOW! Figured I would pass on what I experienced to help others who might be feeling what I was feeling!
