I got my intake on and got my car fired up but it wont stay running for very long. The timing is correct, and i've tried clockin my maf but it just wont stay running unless you keep your foot on the gas. heres the set up

systemax II intake ported for an 80 mm throttle body
bbk 75 mm throttle body and EGR spacer
C&L 73 mm maf
19 lbs injectors

anybody have any ideas on whats wrong? Do you think I'll need to get bigger injectors, or just adjust something?

 

did you calibrate the tps and reset the computer?? if not start there

 

how do you calibrate the tps? will i need to mess with the iac any?

 

is the car idling low?

 

it wont stay idling long enough for me to know. I start it up and then it just dies. or i can start it up and hold on the gas and keep it at about a grand or so

 

Why would you buy a 75 mm t/b and a 73mm maf? No sence to me.


Have you checked for vacuum leaks. Is the maf calibrated for the injectors you have?

 

so if u start it and hold it at 1k it will run? turn the idle screw up

 

well i got the maf before i got the throttle body. i just got the maf to go with my stock intake and tb and then i got a new tb on friday so i said hey why not put my new upper end on. that was probably a bad call on my part

 

Methinks too big of a throttle body.

 

na tb is ok
