You were right !!!! It was the Presure sensor. First I checked the fuel injectors to see if anything changed I d/ced them one by one to see if anything would be different, but they were all working. I checked a few vaccum hoses, than I checked the Pressure sensor vaccume and it worked but i d/ced the plug and I revved that baby up and it purr'd like a kitten. thx every1 for all the good suggestions and help tips and also Aaron Cake thx bro. I also reregrounded the motor and tranny. (yes thats re and re again) twice heh.)
P.S I went to Discout Auto parts to see how much new injectors run they were over $100 dollars and Reman injectors ran $70+

d/ced = dis connected the plug of the pressure sensor the sensor that is on the left side of the engine bay it is bolted on to your strut wall its black has a plug in the bottom of it and a vaccume hose on the bottom aswell, also on the right side of it is a adjuster

Yea i unplugged it too but all it did was run smoother with less boost pressure. It felt slow.
and then when i plugged it back the same hesitation came back

Yea the hesitation went away. Its a whole lost faster now than how it was with the hesitation but its still slow compared to how it used to be.

Rotary Yankee I was doing some searches on RX7club.com about the same situation we have. I came to the conclusion from reading several threads that our problem is the 6th ports that are not working properly. I also checked mine and one is not working. So Im guessing that if I fix that and reconnect my pressure sensor everything should be fine. I will be trying this later this week. Go to this site and read this. Its the best one I found.
