whenever i cold start my 87 n/a, i get a plume of white smoke when i rev past 3500 rpm. the car had a recent tune up. can it be that the engine's not tuned properly or are all rx-7's like this when they start cold?

 

First things first, why are you revving your engine to 4K when its cold?

 

well i let it warm up for a minute but occasionally i feel the need to rev it past 3k. is one minute too short? i used to warm up my crx for 5 minutes but i figured its a waste of gas.

 

you don't need to warm it up to leave, but make sure the temp guage moves before going above 2500 rpm.

 

so the plume of smoke is normal?

btw i've been smelling gas in the cabin recently. last time i went in for a tune up they told me my oil-filter o-rings needed replacement but i didn't have the cash.
