i took the supra up the road yesterday after washing my engine bay and all of a sudden the pedal goes died but the rpms are still climing starts to bounce off the rev limiter so i cut the car off half way down the road and let it roll into my drive way ( with no power steering she doesn't turn very well)
anyway so i start looking for what could have gone wrong first check the throtttle cable thats good then i check where it connects to thebracket thats good but then i notice that the bracket on the valve cover was the problem every time the car was at wot the plate that the throttle cable wraps around would slide overtop of its "stopper" makng it get stuck at wot.
so i take the bracket off and found out there is a plastic bushing at the bottom of the braket has decentagraded so the "stopper" has a lot of play in it and thats what is making it slide under and causing my problem. After looking at the braket i can see there is no way to take it apart so my temp solution is to take a peice of tiewire( metal wire) and wrap it around the bottom where the bushing should have been. I guess i'll have to drill out the braket and put a new spacer in and just use a bolt to hold it all back togeather but the tirewire will do as a temp fix.

Cliff note: Bushing in throttle braket broke making the car stick a wot and scared the $hit of me. I wraped a peice of metal wire to work as a temp bushing.

My buddy CJ's dad didn't tell him once he dropped an extension in his IC piping. Right after that he went boosting, and the extension got stuck in the throttle body causing the same thing.

I thought it was hilarious. :)
He pulled it out and was very mad.

Heh. That happened to me once a few years ago, only it wasn't a bushing...

In the Mk2s airbox, there is a circular rubber gasket thing attached to the inside, don't know wtf it's supposed to do but... ok...

So anyway, I'm just cruising along, on my way to go pick up some pizza, when the gas pedal hits the floor and the rpms are pegging 6500. I then start to freak out, I pulled the car out of gear, tried unjamming the pedal, pushed the clutch in, nothing worked. I shut her off and pulled into a parking lot. Started car, still pegging 6500.

I call the hubby up, 5 minutes later he's there scratching his head. Finally took the whole intake apart to find this damn rubber gasket stuck in the throttle body. Somehow it got loose and the engine sucked it in. :aigo:

A few months later, this happened to both my aunt and my best friend who both had mk2s. So yeah, I suggest everyone who has this fucking gasket, remove it. IMMEDIATELY.
