I recently replaced plugs are wires on my 93 Sc300, but i reused the old throttle body gasket when i put everything back together. Now when i start the car there is a whistling/ screeching sound that constantly stays through out the revs, Is it because i reused the old gasket on the throttle body or did i mess up the throttle plate inside by pushing the throttle body cable too far to put it back. ( i could not get the screws out of the throttle cable because the head on the screws are messed up, i cant get a philps screw driver in there to twist it) I have torqued everything down, still no difference. Help anyone?
Update: Sprayed carb cleaner and let it sit for 2 minutes, it became quiet but as soon as i revved the engine, it came back and now the car idles at 1100 RPM when fully warmed up![Sad](https://www.clublexus.com/forums/images/smilies/sad.gif)
From what i understand is the carb cleaner stayed in the TB but as soon as i opened the plate and sound came back, i'm assuming its the gasket but i just want to make sure that im not missing out on checking anything, any advices?
Thanks in advance!
