Blu you lost me, you said something the average Joe would have. I said the test was done on a stock car, that is the only facts I have seen about having a descreened MAF that wasn't feeling, thoughts, or internet opinions.

 

IAC can it be cleaned or removed from throttle body to be worked on? If I can clean it I will try, another thing the MAF was super dirty like the truck had been run without an air filter or a really dirty one. On my wife's truck I took some alcohol and a Qtip and gentle cleaned the bars in her MAF because there was a decent amount of build up on it after I bought it. I haven't had any issues since and it helped cure the problems then.

 

I've descreened my MAF, just because. I didnt expect any gains, I know its there for a reason but to me it just seems like something else to screw with air flow. Whatever the case is Im betting its Plugs or TB...

When cleaning TB's for Nissans (not saying ours are the same) when you spray a **** load of TB cleaner in there it gets in the sensor and fouls them out. Its happened countless times at the independent shop my dad works at, having worked for Nissan he knows about it and put a halt to that cleaning theory.

The plugs could be old and the Sea Foam coulda burnt all that bullshit that was built up on em kinda keeping them in contact and once its gone the gap could be too big. Just something Im thinking about.

Also the adding ~5% to MAF tables is bullshit. I descreened mine after it had been to the dyno and there was really no difference in driveability. Hey also Sami, you could've maybe unscrewed the little screw that keeps the TB cracked at idle? could just be a piece of the puzzle or nothing at all haha good luck

 

Well a board tuning sponser told me that, and I am pretty sure he knows a little bit more about it than you... That is why i asked what his trims were doing...

 

I don't know what the trims are doing I haven't connected it to a laptop only had Advance Auto scan to identify what the SES light was. Listen, I don't want this to get into a pissing contest about if you should or shouldn't descreen a MAF....I have end of discussion. Also, I am open for all the first hand experience people have. That is after all what makes this website IMO so great. I do not however care to hear what you feel, think, or thought you might have whatever.....so if you don't have any first hand experience with this issues or had a similar situation don't post. There have been several websites that I hate, FSC is one because everyone over there has an opinion and no one has experience. They think since they think they know something they should tell you, please don't tell me PT is going down this very road

 

don't worry nobody is getting upset...I am not saying the maf table being out of whack is causing you problems, i was jsut merely giving a suggestion...The reason behind my suggest was that since the screen was removed the airflow will not be the same as if it was there, thus your maf table being off...


Another suggestion is that you got some crap stuck in the idle air control value. I believe it is a tiny tiny little hole o that is inside the opening for the valve cover vent tube.

 

Now that is something you can sink your teeth into. As helpful as forums are you also have to deal with Dr. Phil posters I call them, they want you to know what they think, feel, or what their opinion of your situation is....if you don't have something to contribute first hand STFU read and learn something. I will take everything apart tonight and double check it to make sure I am good. I hope it isn't a sensor because I don't want to spend money on someone's vehicle that isn't mine.

 

Good luck with the truck, sorry I couldnt get to your lowering kit sooner.

 

leave the battery disconnected over night. It'll reset whatever codes are being thrown. When you dumped the Seafoam, did you dump it in, and then fill up the tank, or just dump it in on it's own? . . . it needs to go in, and then add some fuel.

The truck is going to idle/run like crap while you're putting in Seafoam in the intake. Go out and run it some more . . . . HARD ! Check your connections and seating surfaces on the TB.

I would not have descreened the MAF unless you get it re-calibrated. It's just like putting on some aftermarket MAF . . . it's a useless mod

-since doing all of the above, you should have your fuel trims reset, so that they can relearn the new air flow trims

 

I disconnected the battery and reset the codes. When dumping the Seafoam in I slowly poured it and then pour the last little bit in and shut the motor just like I always have done with no problems. I will take the TB back off clean it and make sure everything looks good, Seafoam it one more time, install the plugs, clean the MAF contacts, and reassemble everything.
