Hi everyone. I put in new t5 tranny gt40p heads and explore intake and roller rockers had to go wth taller valve covers, got trickflow valve covers with oil breathers in each one. I blocked off the tube coming out of the throttle body. when its warmed up and i come up to a stop it stalls. It has a adjustable fuel regulator and is adjusted to 40 with the vacuum hose on. does anyone know what could be making it stall. it was also a little low on coolant and running a little hot. thanks

Make sure to push in the clutch pedal next time you stop :hihi:. How does it idle? Or does it just stall?

lol ya i push the clutch in. it idles great and starts right up after it stalls.

Ahhhhhh, I really dont know. One would think if it would idle fine it would just return to an idle and not kill on ya. Sounds like the clutch it disengaging all the way when you stop. Does it shift hard at all?

the tranyy is fully seated against the bell housing. i'll try to adjust the clutch ans see if it helps and check the tps and run a koer. ill let ya know what codes and where the sensor is thanks

I'm guessing when it stalls the CEL comes on? I would recommend checking codes, that will probably help a lot.

check the IAC too. mine did that to me for awhile and i couldn't figure it out so i just started testing TPS, IAC and anything else i could think of. turned out my IAC was shot.

it has a new iac i ran a koeo test and got these codes. i also realized i never hooked up the vacuum hose from the intake to the vacuum tee. i know im a knucklehead
29 insufficient input from vss
31 evp below min voltage
66 VAF/MAF sensor below min voltage
82 air diverter fault

29 is part of your stalling
66 need to check the connections at the MAF sensor:bigthumbsup
