So I cant figure out what is going on with this car... I start the car and it idles normal then if I give it gas when it comes back down it comes really close to dying but usually catches itself and stays running back at a normal idle. (I blame that on I need a tune since the engine build with t9 cam) However as soon as I hit the brake and drop it into gear the car stalls without a second thought. Its just like it feels the load of the trans and does nothing to counteract it. Any one have any ideas?

 

i would say the tune is a big issue but also check the idle air control motor on the throttle body. try cleaning it or replacing it, definately get a tune in it tho.

 

What are the specs on the cam?

Do you have a higher stall converter in it?

 

F9 232/236 .585/.600. 114 LSA

Stock converter, and a 700 r4 I'm not replacing the converter until I do the tranny build later on

How do I check the idle air control motor, Ohm it? Or just put some voltage to it off the car

 

You're definitely gonna need a stall and a tune.

If that doesn't solve your problem, then look elsewhere.

 

there are special tools that will actaully activate the iac for you but no dont just put 12 volts to it, thats a good way to wreck it, i would just try cleaing it first and see if that helps, agree with SEPSIS that a tune is most likely your issue, i put a cam in my old 96 vortec half ton, wasnt very big maybe 480 lift and the thing would hardly stay running before i tuned it. get the tune out of the way first before ya start chasing too many non existent problems,

 

Ya I guess I'll have to get a tune and see how I stand

 

Sounds like a vaccum issue to me. Can I ask why you didn't get a converter with that somewhat of a mild cam. You know it's gonna act like a pig right. And running the stock converter with a decent cam will always have vaccum/surging/powering through the brakes isssues.
