From a stop(idle), when starting in any gear even reverse, the truck at start off begins and as soon as you start accelerating into the gear and right after off the truck(smooth to this point), truck idle cuts out. Also the Battery & Brake light turn on the cluster. Not sure if its electrical or carb or vacuum lines. I cant firgure it out, all I can do it crank up the idle on the carb to help it, but very little.

Its like the the motor either has a bad ground somewhere, or its the carb not working properly at that particular point. Once you get passed the 1-2 sec cut out by apply more pedal, its smooth and runs fine at all MPH. So picture ever time you switch gears, you have to compensate more pedal to get passed the beginning of the gear to keep the motor running. If I super gentle add gas and move into the gear, it is ok, but if you give it just enough gas for a smooth gear shift, it cuts out. Give it more pedal, its smooth.

Another test I have done, is if I smash on the pedal from idle, the motor cuts for a sec that catches up. Should it be more responsive?

What could it be?

Engine starts up fine with 2 pumps to the pedal and click. Warms up Fine, Idles fine, passed smog. Replace spark plugs recently. But have only had the truck for 1 1/2 w/no records of the past. Currently has 120K on her!

Thanks.

 

If the battery and brake lights are comming on, then your alternator is probably going out. That will effect how the truck runs. Have your alternator tested to see if its good, your truck also has an external voltage regulator that can also go bad, but either way it sounds like you have a voltage problem.

 

Thanks, I will have to check it out. Will take it to Vatozone and have it tested soon.

 

If its the alternator, upgrade it.

Thanks a ton for the link, The more I drive this truck, the more Im sure its electrical causing this issues, If infact its the alternator, I will def upgrade to the 60 amp version VS this 40!
