i had the same problem and it got worse and worse it ended up being vacume hoses and bad solonoid

 

Well if you havent upgraded top silicone vac hose I would do that right away.

 

I have replaced the O2 recently but I have not tried running it disconnected yet. I'll give it a try though.

I also have replaced all the hoses with silicon.



Thanks

 

heh, rx7s have never ending problems, now i'm getting hesitation in all the powerband, like i'm riding a bronco...



i'm gonna check the PFC and the plugs.. i had a couple vacuum leaks and fixed those, it might be running too rich now and messin everything up now

 

could it be a fuel cut? if it didnt have the pms thats what i would say it was.

Are you sure that your clutch isn't slipping?

I have never heard of that much hesiataion. Could you give a better description?

 

i think my tps is out of range, it isn't reading correct voltage on the PFC, i'm going to adjust it and see what happens now...
