My RX7 will not idle properly.. When I drive it through town.. it sometimes Idles and sometimes it doesn't ..
I think its a compression problem.. I have tried everything I can think of and it will not IDLE consistently..

Its a 1988 RX-7 13B engine...

 

I got the same prob, I believe its a sticky injector, you should check for Vaccum leaks

 

I searched all over the engine..no vaccum leaks...I know when I am at 65 mph on the highway and I give it gas in 5th gear.. it doesn't increase speed.. like it won't go..then sometimes it will go(Both tested on a flat straight away)..

If Injectors .. I think it would be the primary ones... i would have to take the top of the engine off.. am i right on this?

 

All you have to take off is the intercooler(turbo) and the upper manifold. Then you should be able to easily reach the primary fuel injectors.
