Hey guys, just 2 weeks ago I did my Throttle body mod. I really like it, only one thing though...

My idle is now kinda stumbly. It doesn't really stay still at 750. It kinda swings + or - 100 rpm. When i removed the UIM, I disconnected some vacume lines (which put back in), some where a little hard by the connecting tip. Could this be caused by a leaky or semi-broken line.

Oh another thing, when it's cold sometimes it doesn't pick up really well, like the turbo wont want to spool. I kinda feel this is asociated with the same deal.

Thanks

 

After doing the TB mod both the idle speed and the TPS need to be reset. If you still have the problem after doing those then look for a vac leak.

 

I've tinkered with the idle, it doesn't seem to do much. I've look on how to reset the TPS, any write-ups? I don't know how.
