So.... In an attempt to replace my pcv valce, i broke the tubing that connects to it because the new pcv valve was much larger than the one that was on there> So i temporarly duct taped it, and clamped it. However it still hisses. Anyone have some help on what to do from here? :(

I got the k & n filter at my local advance auto parts, for $65 plus tax. And thank you guys for the tips on getting out my pcv valve. I'll change that and clean the IACV and possibly my EGR and tell you all on how the performance changes.

Alright, I own a 93 es300. I went out and bought a cheap lil PCV valve to try to help my milage and power, turns out i cant get the damn old one out. Anyone have any tips for gettin this sucker out? its a real pain, im scared im gonna break something. Also, im staring at what i believe is the IACV, but i have no earthly idea on how to clean the stupid thing, or even if its the right thing i should be cleaning. The idling hasnt been as bad since i put a k & n filter in there but its still pretty annoying. oh, if anyone has a word on some good fuel additives to clean the carbon and other crap outta my engine, could you let me know? Much much thanks
