I bought a stock TB with the grind mod a while back from a member and I can't get this thing to work.
I installed the TB and followed the TB reset guide from an old post.
I don't have a scan tool, so I disconnected the battery and then did the "sneaky ECU reset"
I followed the rest of the TB reset and started her up.
the revs hang around 1300rpm and if i touch the throttle the revs climb out of control and i have to shut the car off.
I've checked and rechecked all the usual suspects.( hoses and wires) and still nothing.
I've tryed the reset 3 times today and now I'm ready to throw the TB into the lake.

Any advise?

Thanks

You have a leak with the oil vapor hose that goes into the tb

Tbal right, It worked very well for me, one time the car stopped responding to the fuel pedal when I installed my CF box, so I assumed something changed to the TB (air quantity). I opened Tbal's thread and did exactly what he wrote and everything is fine since then.

Thanx Tbal

Another way you may go, you can recalibrate the TB using STAR, there is a procedure in start that takes you step by step, it involves raising rpm to a certain level and trigger the "yes" on STAR at that same time.

The issue, as I see it, is that you really don't know what was done to the throttle body before you purchased it. Did the prior owner possibly remove the throttle blade and not align it properly upon reinstalling it? Perhaps he/she couldn't get it to work either and passed it on to you?

Thanks for the replies guys.

I was following Tbal's post about the "TB reset", but I don't have a tool to reset the ECU.

I'm going to turn the TB blade 180 and see if that helps. It maybe possiblt that after the grind, it was put on backwards ( if there's even a difference)

All the oil vent hoses are attached and I'm confident that the TB is seated properly.
As the last poster said - I just hope this isn't a dud.

Thanks for the help

Some pics in my thread that might help with orientation. Best of luck

Grab any cheapy scanner... it will do you good in the long run too. Mine has paid for itself about 10x over now. I only got it because well other members told me to invest in one asap lol...

Sorry the reset didnt help... try it anyway and skip the scan tool part...?

Guys - thanks for all the help.
Still couldn't get it to work.
Gives me a good reason to buy a larger TB instead
oh well, onto the next MOD

I know, you did F***** it up so that you have a reason to convince the wife/gf you wanna buy something important for the car ,

You love the power with the new 82mm TB, I would recommend to let the vendor grind it for you to get 85mm if possible. I would recommend TTM for the TB.
