I have a 1967 Chevy 1500 fuel port injection that runs great! Until it gets warm, then it still runs. Until you press the gas, then the motor cuts out. Any suggestions? Plugs, plug wires and distributor are all good. Ohh! Also no one seems to be able to read the computer. Any ideas?

I don't think 67 had a factory computer.

What is it a 67 or 97 truck? When you say the motor cuts out -did you meant it'll stall or bogs down terribly w/o stalling?

It is the very first year with a computer.
When it warms up it will idle fine, but as soon as you press the gas is spits, sputters, and dies then takes 10-12 mins to start again.

I'll tell what show us a picture of the computer and will proceed on -A 67 don't have an electronic engine management system unless you're referring to a 76 that has an ECM in the distributor for the ignition system, that's all-Verify the year of the vehicle
