My Hummer is an bulletprood TANK !!

seriously after owning the hummer the road is clear infront of me everyone would move out of my way without horns or hi-beams and no tailgating too,

 

Are you making the assumption that a battery disconnect "resets" something?

Your H3 stores the last 300 ignition cycles (the last 300 times the motor ran up to full operating temperature). The PCM is flashed based, no power needed to store the ignition cycles. Disconnecting the battery does not erase anything, touching the negative and positive disconnected battery cables together, clicking your heals together while whistling.... none of that resets anything. The ONLY way to change that is through a flash interface, like HP Tuners etc... or box learning over hundreds of those 300 ignition cycles.

 

could be but i am sure it's not out of my mind i can feel my shifts are smoother

earlier was slow hesitated shifits
now crisp but smootg shifts
all under normal driving condition

it almost transferred from slushbox to DSG

i am 90% positive that driveability improved it's not based on "Action" effect

i am not sure what exactly happend on the ECU
my car idle is fine driving fine too shifts were not very smooth now it's smoothed out


maybe it's the TCM or TCM part od ECM
is these transmissions adaptive to whose behind the wheel? maybe it got confused from different drivers and the battery D/C did anything to Transmission shiftpoints or whatever


on my vw eos it's an dsg right after disconnectinf the battery it shifts buttery smootg few minutes later shift quality will decrease

Eitherway what i did if anything it's harmless to the car and could be good for the car justclike rebooting any electronic machine


THANKS,

Thanks

 

My head is spinning trying to follow this thread

 

Amen...I feel like I've been drinking


Nice try Doc...but even if you missed your mark there are others that read/benefit from the knowledge share

 

scratch your hair it'll hep you focus and concentrate

 

WRONG,
I removed my TB and found a thick buildup of sludge, plenty to disrupt the air flow.
It's held on by 4 screws. It can be removed, cleaned properly and reinstalled in about 10 minutes. I do it at least once a year and clean the MAF at the same time. MY truck runs great.

 

that's why i mentioned cleaning the edges of butterfly valve and the surrounding

this is the only restrictions when idling the car with partially closed throttle

i am afraid that i'll damage the gasket by removing it

right now i don't dare to clean the maf
cleaned plenty of them before without issues(once it messed with rubber gasket in maf unit because of the contact cleaner *i assume maf cleaner is harmful to rubber too right? *maf cleaners are not available here)

but i just won't mess with my hummer MAF at least not now

i run stock airbox and filter so there shouldn't be containments on MAF wires

car that is 5 years old with 40k miles what the TB gasket status is? still seals well, will removing tb hardens the rubber or damage it?

thanks

 

The H3 TB does not have a gasket, it has an O ring in a groove on the mounting flange of the intake manifold. When you remove the TB, the O ring stays on the intake manifold and it gets sprayed with nothing. If you leave the TB in place and spray it, your O ring does come in contact with whatever you might be spraying it with. If you use TB cleaner, it will not harm the O ring. Do not make the assumption you can just spray off the TB with whatever solvent or cleaner you have available, that is why they make specific TB cleaner.

Just trying to help, clean yours whenever you want.

In this thread I have pics of my super clean PP TB backside, no O ring.

@Doc Olds

i was talking about maf sensor
earlier i've used electrical contact cleaner made by CRC on VW MAF

the rubber in the maf unit housing bulged out and i am not sure what happened it may not seal very well i think it was temporarly and it went back into shape when installed otherwise i'll know something is wrong if the gasket failed to seal, and the MAF gets incorrect air mass reading
car was performing the same or better ( i was lucky)
i admit i sprayed it heavilly

i know the gasket stays inside the engine intake manifold

i am not afraid of solvants damage to gasket
but afraid of removing a perfectly sealed TB and this will let air leaks past the gasket

this is why they require gasket changes in most of the time you disconnect any part that has gasket

it's because of all the heat it's hardend and won't seal like fresh rubber after R&R

hope my point is clear and error free

anyhow i'll get into cleaning my tb soon

i did an on spot TB cleaning on trailblazer before without any issues that car has idling issues due to alternator output( replaced with GM rebuilt unit) roll any windo or use some electrical load and the veicgle will almost stall my hummer is fine in this concern

what your openion on WD40 for TB cleaning?
i've cleaned TB'S before with almost half a can that went into the engine and the car started immediatly without any smoke or anything( i probably could pour WD40 in my gas tank)

thanks
