1.8 1zz intake gasket...which?

[jasonvibe]

Okay , which is the correct gasket? DUe to poor idle when subfreezing and PO133 ...I purchased my Felpro MS93942 two months ago. waiting for warm up(no garage). Back then,the toyota dealer by me had the 17171-0D020(black), which is identical to the Felpro I installed. I did not change the throttle body gasket, it looked like new, not flattened. Just weeks after changing mine the weather turned cold again this week, and the PO133 popped up. Along with poor ideal half way thru warm up. There is a Toyo bulliten stating the colder it is the more the intake leak will show a "code133". Someone stated there's another...17177-0T020. Which is the latest for 1zz engines ??? I have wrenched more complex stuff than this. Maybe mine is bad again. Or a leak at the throttle body gasket? I could not have messed it up....? It runs good except for the above stated. I need replies from someone who installed one lately from Toyota. Please...thanks in advance

WALLYUWL, left me this post 3/26 on another string. SO I gues Ihave my answer."I got an intake manifold gaskeet from my Toyota dealer a few days ago and it is part number: 17171-22060. Made in Japan. It is sort of a rust orange color. They said it is the only part number available to them for an intake manifold gasket for the 1zz engine. " In addition. The older Toyota part 17171-0D020 appears to be the same as Felpro. Both made in USA and both feel the same. Yes, I touched both. ANd both have been in short supply. Obviously the Dealers should not be able to get the old #. But mine did. That explains the 4 days to get it. But I used the Felpro. Now seeing the 3 year old bulletin. I have to get the newest Toyota part because the bulletin mentioned codes popping up @ subfreezing temps . And that is where I am at now. UPDATE 4/3 I have now changed the intake to the orange type. Along with new throttle body gasket. Did not cure my poor idle during end of warm up. Once fully warmed up. It idles fine. Maybe idle speed control is shutting down too soon?
