    Default 94 Chevy 1500 with 5.7L baugs down when throttle fully pressed

    My 94 Chevy idles fine and has no problems running or anything, But when im at a stop and full press the throttle to the floor it cuts the motor out and kills it unless i let off for it co idle again. It raps up fine at half and 3/4 pressed quickly at a stop but quickly pressing it to the floor cuts the motor out. Some one Please help

    Default Throttle Position Sensor (TPS)

    Sounds like a Trottle Position Sensor (TPS) The PCM is not getting a signal that the throttle is in a Wide Open Throttle (WOT) condition. Check the connector/connection.

    well i cleaned the connectors and what i could and it didnt help. Could this possible be foul spark plugs? It has been ran more than just idleing for about 5 months because we were changing the body on it.

    Could be a clogged fuel filter...

    My '97 with a 350 does the same thing. Hopefully this thread will shed some light on a solution.

    I know maybe someone will catch this thread that has fixed the problem. But today i went out and warmed it up at our shop while i was working on our loader and once it warmed up it didnt do it today? Has me fooled, i think i might replace the plugs in it if it keeps doing it

    My mom's 98 tahoe did this for awhile and when I got around to looking under the hood i noticed that the intake "tube" had slid out of the box with the air filter and down just a bit so when you nailed it it wasn't getting enough air, but ran great with less throttle. I gotta think since you have been under the hood you would have noticed this but maybe pop the filter off and see if it still does it. It sounds to me like it's running short on air, fuel, or spark.

    Im sure its getting enough air because i have a K&N intake and filter on it that i have cleaned within the last month.

    Either that or it's a good commercial idea for Airaid intakes
