so i just wanted some opinions from everybody and what you guys all would do...
my rx7 was running perfect before i just got my rx7 1990 exhaust system done to a single pipe 3 inch and i just barly put on a new intake and now my car is starting to act up on me it keeps on dieing unless i pump the gas pedal but i replaced the fuel pump and it is still acting the same.... so where did i go wrong? i need help quick!!!!

 

Pressing the gas pedal doesn't supply more fuel; it supplies more air. The ECU supplies more fuel when it measures more incoming air. I'm not sure how this lead to you replacing the fuel pump.

Did the problem occur when the exhaust was installed, or after the exhaust AND the intake?

What is this intake? Some sort of cone filter?

Is it stalling because the idle speed it dropping? Does it have an erratic idle? Your problem could be as simple as a vacuum/air leak somewhere in the intake path. Check anything that has been messed with.

 

the car ran perfect with the exhaust done to it and the idleing of the car sits still at 900 rpm rev but i guess after i installed the air intake the car started to act up on me and be all weird and dieing on me at random times like i could be rolling and it would just die and the car could just be sitting then just die... could it possibly be that i need to remove the air intake and go back to stock?
