Ive already bumped a couple old threads, and tried to take over others peoples threads but since my question has gone unnoticed i figure i will just make my own

The first half a dozen start ups where great, turn key and it fired right up.

Then i was trouble shooting, i played with IAC to make it idle higher, and i took off the IC pipeing to take care of a leak i had

Now when i start, if i dont help it with the gas pedle it dies! This one is so easy but im caught up looking at so many things i know im overlooking what i need to do.

I already bought a new TB and TPS (cheap on eBay why not?) and im open for suggestionsMy timing is probably messed up but i havent played with CAS between when it started fine and now stumbles

Thanks much!

Notorious MAS problem.

Have you cleaned it thoroughly?

Also, if the car learned fuel curves after you fixed that leak, its still on the "leaky map" Reset your computer as well.
