Hi I got a Toyota corolla 160i gle and it was parked very long so wen i started it wen ideling no smoke BT wen hit da fuel it smokes and on take off BT wen driving it does nt smoke

Generally, it may smoke on startup for a few seconds then quit and seem to run fine, then you hit the gas and it smokes again, so Is it white smoke gray smoke or blue smoke? Because IMO it's either a bad head gasket, bad valve guides, rings are going bad ot dumping to much fuel into carb or injectors.

1985 Ford F150 302,5.0 Smoking running Rich and idling high and low

first of all u need to determine what color of smoke it is and is it coming out of the exhaust pipe. black smoke means excessive gas burning smoke means burning oil ...white smoke if seen in warm weather conditions means coolant leak into cylinder heads... but as running rich and high low idle might have a vacuum leak or carburetor need new base gasket or rebuilt ... good luck

This is my first ever Ford truck. I can't figure out why while it is running it sort of surges. When I shut it off and restart it I have to push the accelerator pedal to get it started. It puts black...

Runs great but will quit running , smell gas also

Sound like a rich by a long way; are you check if have smoke in exhaust? Black smoke is fuel, blue smoke is oil.

Also, your injectors are to big and is running rich.

1989 Ford F150 runs fine then starts smoking black smoke and quits. After 20 minutes will restart and go again.

You have an excess fuel delivery problem. Black smoke indicates that too much fuel is entering the combustion chamber. If this vehicle has a carburator, check the float bowl level. If it is injected the main things to look for would be a stuck throttle position sensor or an injector that is not closing

Was running fine then stalled suddenly. when it started back run rough at an idle black smoke from exhaust then press the gas pedal and it quit now it will not start at all

I just had a similar situation. The truck would run fine and then the Service Engine Soon light would start blinking and the truck would go into "limp" mode. It would eventually stall. Strangley though, if I turned the key over and then restarted it, it would start right up and run again. It ended up being the IPDM (Intelligent Power Distribution Module) that was bad. It cost me $520 to replace it.

Blue smoke is oil, probably a sign of worn rings, has it done quite high mileage?
