I put a professional products 65mm TB on my car and it was crap. Before I put it on it felt like it would stick. Anyway I put it on and the car idled at like 2k rpms, so I set the idle and tps like it says and it went down to 1600 rpms. The idle screw wasn't even touching the throttle. The only thing I noticed is that if I unpluged the IAC it would idle perfect, and the hole in the TB going to the IAC was sucking alot of air. Anyway I took it for a ride and it ran like crap and missed and the throtle stuck once so I took it off.Was it something I did or are these junk???
