Hello,

  Here is my current setup

        90 Chevy 350 bored .060
        CompuCAMS 2030 Camshaft
        Full fulcrum Roller Rockers
        ADS SuperChip

        The Engine is in a 90 Fullsize Chey Truck, the Aircleaner lid has been
flipped to make sure that it is getting enough air!

THE PROBLEM

        The problem that i am having is that when the engine is between  Cold
and Warm, Not right after the engine is started, but before it is completly
warm, when you step right off idle the engine about dies!  But if you floor it,
it will stumble then run fine all the way through the RPM range!

I have replaced the O2 Sensor,
Replaced the TPS
Checked the Timing
Both Injectors seem to be squirting fine, i checked them with a timing light and
there is a nice cone sprayed on each one....

The engine also seems to run better cold after the bog, but when it is completly
warm if feels like it has lost a little power....

Any ideas?

Andy
