Thanks but i had found out which way the injectors are suppose to be installed but changing both fuel injectors didn't solve my stalling problem and this TBI does not use the steel O-ring all it use is the small rubber O-ring that sits at the bottom next to the screen filter and a big rubber O-ring on top.
With the new fuel injectors the car is stalling quicker now, start it up and it stalls foot on the gas it doesn't stall, foot of the gas it stalls and it doesn't stall when i uninstall the air cleaner.
Is there a way i can reset the Idle Control Valve and where can i find the fuel and air mixture screw?
