    Working on a customer car and had a 2k idle and couldnt find any leaks.... pulled throttle body off and see this huge gap... makes sense now.

    Is this a rebuild gone wrong? Ive never seen one come off a car like this... usually carbon build up at best holding it cracked.

    Maybe it's a 2g throttle plate.

    Throttle plate is installed flipped & not in proper orientation. The edge on the throttle plate is not right angle square, it slightly angle for when the plate is in the close position. Fix is removing the plate and flipping it around until angled edge mates up to the TB throat in the close position.

    So they point it in backwards and crooked. Ill flip and realign for them. It also has no throttle stop(sensor). That shouldnt matter though I wouldnt think for high idle

    You'll need to add something for a throttle stop so the plate doesn't stick when fully closed.

    It's hard to say exactly how it's orientated now. could be flipped front to back, rotated 180 degrees, or both. When I'm trying to sort out a "basket case" TB plate I add a mark for a point of reference & test it in different orientation with the screws removed but the hole visually lined up. When you get it correct the plate fits proper, opens & closes & won't stick or bind, & then add the screws. It's easy to tell when its in correctly.

    This doesn't really take a lot of time & it's easier with the return springs unhooked or removed.

    Ya just a pain when not done rightthe 1st time... they put this iac on.... little worried what else is hidden.

    Long story short car came from a guy who got fed up with the shop that was working on it. So far ive had to rewire gauges hooked to headlights and sensors that were hacked into the harness. Thus car is why people say dsm is unreliable.

    I on the other hand have a 93 that I daily 300 miles a week with barely any issues.

    I just finished a car for a guy that wouldn't idle below 2k worth a damn. I pulled his tb off and same thing. His buddy rebuilt and ported it and got into where the plate seats and caused it.
