timing after H/C/I, car dies.

[QCmustang94]

I just did an H\C\I on my 94 gt. GT40p, e303, 1.6RR, cobra intake. The problem is I time the car and it runs alright for an hour. When I start the car 2-3 hours later, the car just rev at 2500rpm and stall.

I just replaced the intake gaskets and they were not the problem. Maybe the car really need a dyno tune?

you have your throttle blades opened too far. Turn your idle screw down, set your timing to 15 with the spout removed, then install the spout again, buy a BBK or Prof Products throttle body that has the idle mods in it. And yes, a prof dyno tune will get those drivability bugs worked out for you.

Thanks! I'll try this. I have a 70mm FRPP throttle body and there's a screw on the top. Is it this one you are talking about?

That one will work.

that is actually the idle air control and it coule be part of the problem, turn it counter clockwise.

what kind of gains did you get?

For the Gains, I don't know. I drove the car for 2 minutes, i'll tell you when I'll go on the dyno.
