ok about 3 weeks ago my car started staring up funny. like some mornings when you crank it up ( usually cold) . It will not wanna start right up. after alittle bit of playing it does. but it acts like to much fuel is thrown in and dont wanna idle worth a crap and it revs weird like its blown. sounds about like a wrx exhuast. but after 30 seconds or so it will jump from that. to normal rx7 idle. its stock ported motor. has tbmod/ported manifolds and other little bolt ons. still pulls like crazy!! is my baby dying slow??

 

I think the TB mod may be causing this. Since the extra plates are gone they no longer restrict the air flow when it is cold and that is causing the problem. Just an oppinion though.

hmm thanks man. anyone else

 

my rx does that but im thinkin it just needs a new motor.... mine is dieing slowly.. sometimes mine would flood and there for i would have to leave it sitting there for a while then it would start after like an hour or so.. has yours ever done that?

 

Kind of random title for your thread dude dont you think?
Anyways it defenetly sounds like it has to do with the porting you did. Ported engines have trouble starting and really shitty idles from what ive seen. Once there heated up there fine, kind of like not having a cold start system. Is it a new engine? If its older id check compression. And by the way its always helpful to list your mods through a sig.

 

I agree, read up about the TB mod, many people complain about shitty idle when it's cold, most of them say that they have to hold the acclerator until it warms up properly
