When I feather clutch it just to move my car like 3' the rpms dip to 500 or a little less and take about 1 sec to recover. It seems to be getting worse as time goes on. Iam in need of new plugs after about 20k miles on them. The engine has about 35k miles on rebuild and 20k miles on new turbos. I have a SS dp, cat back, and profec-b. Could this be a symptom of bad plugs or something else. I really dont think my compression is at fault but I wont know till I do a comp. test. Do you guys think this will cure the problem? Anybody else have this problem, its really embarsing since it looks like you dont know how to drive a 5 speed. Other than this my car runs perfect, is rev happy, and has strong boost.

well, either way i think you'll find 20K miles on plugs is time to change. I change every 10K, and many change between 10-20K

I don't know whats wrong with my car, but I had my plugs foul out after only 2500 miles on them. It was very difficult to start, but after started, it ran fine. If I were you, I'd change them anyway, since they're due for a change. 20K on plugs in an RX7 is A LOT of miles.

Harder starts is one symptom. Another is at idle and giving it minimal gas, it seems to bog down. Also, at the top end, it seems to not want to "pull" as before.

Looking at your sig, you DO have a fuel delivery fix don't you?

It probably is the plugs and yes Iam going to change them right away as soon as I get paid as seeing I have to pay a lot of bills and 3 TRAFFIC TICKETS THIS MONTH!!! Thancks for your help and any more comments will be welcomed!!
