Hi all,

Firstly, thanks to all for this great forum. i have learnt a lot from here.

I have imported a 1992 Mazda Rx7 efini Type R

The mods on the vehicle are the ffg:
Blitz twin air intakes
Blitz Bov
Knight sport ecu and 300km speedo
Racing clutch(not sure which brand but shaped similar to excedy single sport series)
Full down pipe exhaust system
Feed elbow intake

When i received the car:
1.Fuel was leaking from the bottom pipe of the charcoal canister, I place a bolt there and kept the fuel cap loose to avoid pressure building in the tank
2.Whilst driving, if you give it gas, it will stall for a second and then will go.

I am not sure if the fuel is too lean(using 95unlead) or is it because of the fuel leaking from charcoal canister.

Other than that theres no problems with the car. What should I look at to solve the above two problems

Thanking in Advance

 

2 things.
number ONE..fix the Fuel leak problem.

number TWO...FIX THE FUEL LEAK Problem

Sounds like TPS but then again you have a knightsport ECU and who knows what that is set up for.

 

After going through the FSM, there is a two way check valve on one of the fuel lines. Most probably that is not working like how it suppose to be

 

Okay will check it out. Do i have to drop the tank or can i access it from where the pump sits ?
