    I just bout a 1994 isuzu pick up yesterday, the radiator was leaking so I changed that, and the battery needed to be changed so I changed that as well, now the car starts but I have to pump the gas and keep my foot on the gas for it to stay on, as soon as I lift my foot off the gas it shuts off. What is the problem?

Change your fuel filter and run some fuel injector cleaner through the gas tank. Take your air intake hose off the throttle body and spray some carb cleaner and get all of the black gunk out of the inside of your throttle body. Change your spark plugs, spark plug wires, oxygen sensor, distributor cap and rotor. Have your ignition timing set, the correct setting for your 1994 Isuzu pickup is: 6 Degrees

Try this.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

    I just bout the car and when I bout it the radiator was leaking so I changed that yesterday and started it this morning to make sure there was no leaks, when I started it there where no leaks but I had to jump it so I decided to change the battery all together with a brand new one it started just fine but after about 10 minutes it slowly started to idle down until it shut off. Now it will start but only with me holding the gas pedal down and keeping my foot on the gas to keep it on do you still suggest this method

It starts and will only stay running if I keep my foot on the gas. As soon as I let off the car dies.


sounds like idle control valve. allows air to get into the motor if the throttle body is closed. aka your foot off the gas pedal. sometimes you can try to clean them, but most times that doesn't work.

Starts but you have to keep your foot on accelerator


Powertrain Control Module
There is an idle speed motor on the side of the throttle body, I would thouroughly clean throttle body.

My 1998 dodge caravan won't stay running. starts up but shuts down instantantly or when i take my foot off the gas pedal,


ok i have a 1998 durango with the 5.2L 318 engine. had trouble with a bad cell in my battery. I went out bought an optima red top battery for it 800cca. put it in and had same trouble. No start without putting foot on gas. wouldn't stay running without holding foot on gas. CPU has to relearn it's programming once you unplug it for long periods of time. mine was without power for about 2-3 weeks till i got new battery. Start with this.. first check under air filter make sure a squirrel hasn't made a mess under your air filter and it's clogging the air intake. Then pull off the lid to your injector cover ( the screw down lid coming from the air box ( with air filter in it) to "carb") make sure all your cables move freely. put that all back together and close hood. Start truck with foot slightly on gas pedal to get started. keep it at about 1k to 1500 rpm for about 1-2 minutes. Rev motor to about 2500rpm and let it die out if it will. Get out lock doors with key fob if you have it. if not make sure to lock doors. ( trust me it worked for me) let sit for 5 minutes. come back out and unlock door and relock door 3 times with fob ( if you have it ) or key if you don't have a fob. Then unlock it with the key and enter vehicle. Start truck as before and keep it around 1k to 1500 rpm again for about 30 seconds rev it up and should keep running. Mine did. I think the iac was stuck from sitting and has now since loosened up.
Good luck hope ti works for you.

If you were driving a Ford, I would say your throttle position sensor is bad or out of adjustment. This device should be around the throttle plate/throttle cable area.

Starting my neon and keeping it running.


I believe you should just set the idle higher at the throttle body or MAF so it gets enough air and fuel to keep running. Those butterflies have to be cracked open a little to start with so it's getting enough air to run without you having to keep your foot on the throttle pedal.
