trans problems related to maf help please

[kst3v3n]

OOOOH wonderfull
But what happened,??
is it blown up??
or the computer not communicating with the trans,??
did it throw it into some kind of limp home mode.??
WTF i dont get it.
Did I possibly have the wrong maf tabels from day one??
Why would un-plugging the the maf let it run like a raped ape?
( like it should have) started better, idled better, lots more power
I put up with it running kinda ok for over a year, I just reached a point where it was time to get it running like it should and now I got an a$$ ache

BTW its an 2004 5.3l 4l60-e
some mods. comp cams 212 218 563 lift shortie headers
port n polished dbw t body
valve springs udrive pullies trans go shift kit and tci 2400 stall

Casey 23 or sprayed 99 might be able to give you a better idea. They are most likely working on transmissions right now.
This might not be your problem or it could be something really simple.
Don't listen to any thing I say I don't know anything about mechanican. I only know how to mash the gas all the way down.

simple solutions needed
just removed and cleaned the maf senser, good dousing with contact cleaner looked good before just as clean now. no change.
is there a relearn procedure that i can do, a forced reset ?
can i test the maf with ohm meter?? how and whats goog readings?
how about the signals to and from the maf senser?
simple solutions are the best, any are welcome, I have my nephews this weekend and my truck is broke. I'm afraid to drive it, you know get stuck kids bugging me to go, Pontiac nationals this weekend, 5 year old want his baseball trouphy from the city homedays. oohh this is not good.

Use an electric type spray cleaner and clean the MAF with it. The little sensors need to be clean free to work. As hot as it is outside, it should evaporate quick. Also your TPS or throttle position sensor has a lot to do on how your trans shifts. I had one go bad and it would slam into gear periodically and shift real hard. RED may be able to give you some insight on the problem. Undo the positive cable for like 20 mins and do a re-learn. Clean the MAF first with Electrical spray they have it at NAPA or just about any auto parts store.

Hope this helps,
Jamest

MAF has a direct effect on shifting. your shifting problem is light throttle
or just WOT throttle?
check to verify the wiring to the MAF is not damaged.. did you get a MIL
when it was unplugged? or have you always had a MIL on?
DTC 101-102-103 are MAF codes plus you should have had some IAT DTC.
the MAF also contains the IAT (intake air temperature sensor) unplugged
the computer thinks its -40° intake air... fuels and timing accordingly
seeing as your disconnected the cables (incorrectly) you now probably
need a transmission relearn as well as a full system relearn.
try this procedure...
disconnect the negative cable (only) lead from battery
disconnect any and all cell phones from the cig lighter jacks
press the horn and brake pedal for one-minute or longer.
reconnect the negative battery lead to battery.
youll need appox 200mi to relearn all the adaptive learning sequences

This is good info, My truck always ran better when it was warming up. So now I see why I was told to disconnect the maf. fool it into thinking it was cold only its humid 100. Thats a few pieces of the puzzel.
I got no MIL or codes at that time nor have i since. I did get a chance to speek with Allen ( what a great dude ! ) and there is no way of knowing what was turned off in that tune so Mil or Mil means nothing without knowing.
Shifting problem is at any throttle I must back off the gas the for the trans to upshift. but 30% throttle(guess) at any speed down shifts trany to first and reves the motor like your foot is in the radiator. BAMM that fast bounce of the rev limiter. That's scary since the rear wheels are connected to the phsyco drive train.

I cleaned the Maf yesterday no change the Poss cable off all night- not been out to check yet, but from what this post says, That is incorrect so I haven't been in a hurry to find out it didn't work,

The relearn proceedures (that take 200 mins) is there a link or site that I can go to to study them, then I can learn all the adaptive learning sequences. I did a search but not to much luck, Lots of info On CASE learn but i dont know if that is just v-6??

My truck is a conversion trans plant so if the horn and brake have some thing to do with BCM and other electronic wizardry I dont have it. May be its so you take a ONE FULL MINUTE sitting in your broken truck to realize how much you appreciated it when it was running, well that will work. With the propper cable removed of course.

Thanks to all
