When i press the accellerator the idle fluctuates up and down

From a static position when i press the accellerator and lift while in drive or reverse, the engine begins to throttle up and down own its own and cuts off.... is this due to a bad idle control???

Couple of items can cause this:
manual shift valve, transmission range sensor, idle air control or fuel pressure regulator. Only once I had to replace the ECU.
I would scan for codes first and see what you get.

I have a 66 Chevy pickup, I need to know what degree to set the timing. It's a 292 engine.


Hi, I know a trick to adjusting your timing. you will need an assistant. if the truck has an automatic transmission, you can have someone put the vehicle in reverse or drive, keeping the brake pedal pressed down firmly, press the accellerator pedal, advance the timing by turning the distributor, until you get spark knock. Then turn it back just until the spark knock goes away. this may not be the factory spec, but it will give you optimum performance.

I would think that the TPS is not adjusted correctly. Move it until the idle stops fluctuating and advise how it runs.

The TPS does 2 things...It tells the computer the opening of the throttle plate, and it also sends a signal to the computer when the throttle plate is closed. If the TPS has the closed throttle switch activated, and the throttle plate is open, the ECU will fluctuate the idle up and down.
