Hey guys! so here is part 2 of my high idle.

I cleaned the throttle body, cleaned the IAC valve. Still high idel, can't find any vacuum leaks.

A new IAC valve is $100.00

But I found this:

New TB, with gasket, TPS sensor and IAC for $60.00
This TB is bigger and has no restrictor plate.

Will this give the engine better performance / response? OR what I'm actually wondering, will this cause the engine any harm?

Thanks!
Eric
