throttle response
 

Im not sure if thats the right term but when i tap the gas just a little bit its not that great of a response. It kinda just bogs a little bit. Any way to correct this?

And i also put in an air fuel gauge and im running pretty fing lean. How can i fix this?

any step by steps would be great thanks

new fuel filter maybe?

if your running lean try resetting your ecu first. then check for vacuum leaks. bigger spark plug wires would help with response.

not to sound stupid but you are reading your a/f gauge at full throttle right?

check your O2 sensor ...
it could be bad

First thing I would check is the 02 sensor.
Then, if the RX7 VAF has been tuned correctly and you still have that tip-in hesitation, I would recommend that you try cleaning the throttle body. You can buy "throttle body cleaner" (instead of carburator cleaner) and spray into the throttle body and clean the intake manifold, etc.

I had poor throttle response too. It would kind of stick for a second, then go. I took off the throttle body and cleaned it thoroughly and it made a hell of a difference. The car went from being kind of a slug to being a pleasure to drive - not just off the line, but at all speeds.

You might also want to try taking some slack out of your throttle cable.

tightening slack in the throttle cable isn't going to do you much in my opinion except hide a problem thats already there. cleaning your throttle body, could definately help you out. adjusting the screw on your throttle body could also help, but again, probably could be hiding another problem if you do that. check your o2 censor, but the one suggestion i was thinking of was cleaning out your injectors or making sure your fuel pump is up to par. this sounds like one of those things, just by describing it, you're going to get 20 different answers with a few that help, and 1 that matters the most. good luck bud
peace

I agree...

also, what kind of a/f gauge did you use?
