Ok guys so Im putting together this 2nd gen (87) rx7 for chumpcar and the 24 hours of lemons endurance races. I wanted to eliminate possible sources of problems so I tried removing the air pump, egr system, and oil injection systems.

now it runs like shit. seems real lean, popping and sputtering.

-there are no vacuum leaks
-we're pre-mixing two cycle castor oil with the fuel
-from the three components removed there are aluminum block-off plates bolted and siliconed in.

anyone had this problem removing these components? know where I went wrong?

help a rotary team out!

-Matt
