I have a stock 1993 rx7. I got only an intake and a down pipe installed on it Everything else is stock. Basicly im very new to these car but I generally am pretty good with mechanics. Anyhow I was driving the car, I shifted to second and it kinda bogged down and was barely running. That was first time out. turns out it was just the vacuum line from the boost sensor. Problem solved. A few days go by. similiar situation shifted and then kinda got nothing. I thought it was the vacuum line again. But it wasnt! i have looked all over the car for the issue. The only anomaly I can find is that while the car is running I have "zero" suction from the top intake! it doesnt pull at all and even blows out. Can anybody please help!! I would like to get it going and then drive it up to KDR in PA. All help is greatly appreciated..
