When i start the engine it will run at about 3000rpm .i checked the cables at the carb and the gas.what else could it be pedal

This kind of cars the gas pedal is electronic, that means there is no metal cable to the carb. the first thing is check for any disconnected wire harness at the pedal or on the engine compartment at the throttle body everything looks fine the pedal could be defective

Hi, yes you can fix yourself. Follow the accelerator (gas pedal) cable to the carburetor, at the carb. there should be a spring (this could have come off) that makes the cable retract, have any helper push the gas pedal. You watch the movement in the engine area with the ENGINE SWITCHED OFF. Follow the movement of the cable and check for return action. Lubricate with spray lube on all moving parts. All the best.

check your fuseable links ,they should be in under hood fuse block

Well if it is an older car with a carb.,just adjust the throttle cable.....the cable might have slipped

what car is it? your car using carb or fuel injection

Okay, your freind may be right, that part is called the accelerator pump, it is used for starting the truck, when you pump the gas to start it this pumps a few squirts of gas into the carb. what concerns me is that you hold the gas pedal to the floor to start it, most of the time an internal leaking carb floods the engine and holding the pedal down will let it start, a quick test would be to use a carb cleaner spray and before trying to start the truck hit the gas pedal and see if inside from the top of the carb look and see if you see a squirt of gas spray out, you will need some one to push the gas pedal or you can do it at the carb, if it squirts gas then the accelerator pump may be good and carb may be leaking and need rebuilding but if it doesnt squirt then its bad and then i want you to spray the carb cleaner into the carb and try to start the truck and if its due to the accel pump then after you spray into carb the truck should fire up and run without having to hold the pedal to the floor, if thats the case then replace accel pump if it still doesnt fire until you hold gas down then crab needs rebuilding . good day. hope this is helpful.

This most probably is an issue called "drowning" by some mechanics. There is too much fuel inside your carb and not enough air that is why when you push the pedal all the way it starts. When you step on the gas more air is let through to match the fuel. Remember, do not pump the gas pedal because it also pumps more fuel into the carb even when not running, this will cause starting issues.

Check your MAF and MAP sensor. The first 80% of your throttle signal from the TPS works with the O2 sensor to try to keep the air fuel ratio to 14.7 to 1 with the ECM controlling the fuel injector spray time and timing the ignition. After the 80% to WOT the ECM puts the O2 sensor in to an open loop and takes the Reading form the MAF and MAP sensor to run the engine richer so there will not be any Detonation to the engine and burning holes in the valves for running too lean. That is why it always feel like you get a little more when you ease off on the gas peddle from WOT. Recap check the TPS, MAF,and MAP sensor and wires to those sensors, if you can get the car scanned that would be great and you may find out which sensor may have gone bad, the other thing to is the fuel pressure regulator may be going bad and at WOT the pressure may be to high causing it to run to rich causing the loss of power. Good luck and hope this helps. 

Gasoline- thank you. Warm up is not an issue like diesel is. Sounds like the choke is is either wide open or over choking. With the engine cold, remove the air cleaner and note where the plate is at the opening of the carb. If it is wide open then without touching anything else and engine not running, step down on the gas pedal and see if the choke plate reset itself to restricter the carb inlet. If it didn't, then take some WD 40 and spray the linkages and the rod ends holdin the choke plate.By hand work the plate and linkage holding the gas open at the carb. Then set the plate to wide open and do the gas pedal thing agan to see if choke sets itself back to restricting the carb intake. If it does, start the engine and as the engine warms upm the choke plate should start opening on its own and you are off and running. Roitine question. Is your air cleaner clean? If the choke plate needs adjusting. get back to me. K? Good luck Remember to press the gas pedal down once before cranking. That sets the choke for cold start. Hope this helped you Good luck Note, the WD40 won't hurt anything but avoid spraying with engine running or when engine is hot..

choke stuck open ..dumping fuel..you need to find linkage at cable /carb area and reconnect /lube/replace
