A couple months ago I went and filled my car up after I was just about completely out of gas. Since then my car is constantly dying. When it sits over night the car will drive for about 10 minutes in the morning before it starts dying. Whenever I slow down at a light the car dies, or it dies when I'm going around a slow corner in a city. Almost anytime I'm going really slow it'll die, I have to keep some pressure on the gas pedal at all times to keep it from dying. When it doesn't die it often revs itself up and down like someone is pressing, releasing, pressing, releasing the gas pedal over and over again. A friend thats a small engine mechanic suggested to try Heet and I've went through 2 more complete tanks of gas, one thing of heet each time I filled it up and it hasn't helped at all. I don't know if it water in the line somewhere, or if I'm completely on the wrong trail. The car always starts back up btw.

Thanks in advance for any help! Greatly appreciated!

Hi alexisfire,

Idling speed is too low and if you have insufficient coolant in system or the coolant hoses to the throttle body and fast idle valve is clogged, the symptoms described would occur.

I would suggest cleaning the throttle body and related parts.

Thank you for the help! I haven't gotten around to checking everything yet. I plan on looking up how to check the fast idle valve and the other things I can. My car does have a carburetor though, not fuel injection.

For carburetted models, there is no fast idle valve. An automatic choke system is used.

Carb engine seldom surges and I have encountered such problems when it was the charging system that was at fault.

You should check the fuel cut solenoid (located next to throttle adjust screw) and its power supply which is from the solenoid control unit locarted under the seats.
