Car still have smog pump?
Those lines should be all disconected then.. And your tune should be ste for egr delete and smog delete.
Looks as if someone has already tried to fix your whistle... BBK throttle bodies are notorious for it.
It's hard to tell. But non of those colored lines should be hooked at all..
They should not. That's not what it's for. It's done wrong.... One is vac source. The other is for the egr. The other two are for smog..
Yeah, an old mechanic friend of mine drilled a hole and I guess it worked for a while....
What's funny, is that drilling a hole in the TB blade is likely causing your high idle and inability of your IAC to prevent a surge or hang.
Some people shouldn't be allowed to touch these cars.
I can plug it up too see what happens.
Probably not a great idea. Would suck pretty bad if the plug or w/e got sucked into your engine.
