Check that the vent valve for the fuel tank is not blocked or the fuel cap is not blocked as it may be a vacuum forming in the tank and reducing the fuel flow to the engine. Quick test is to loosen off the cap and see if the problem is still there. If the engine rpm is connected a vacuum operated control (Engine rpm increases when the vacuum is required) check that there is not a leak in the hose /line or loose connection If the engine has done a lot of hours then there may be a problem in the governor control

SOURCE: 1993 Ford E-350 Fuel issue

This can be a common problem among engines with some miles like 50k to 95k range. There is an idler unit that is opens and closes during starting. They get clogged with carbon and stick. I am going to suggest you to look in this area.
You have many other ways to go but it is in the full body throttle area more than likely.
With a 2002 you might be able to get a book and find it. It is usually stuck in the side of the throttle body (carburetor) This is an educated guess but it is worth looking at.

SOURCE: my car threatens to die during idling...the rpm

Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, 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.

SOURCE: engine stalled out,would not start,

This truck is fuel injected, the problem sounds like a weak fuelpump, it runs when you pour gas into it until that gas runs out, the first thing is to test the fuel preasure, if the pump is weak it may run with gas poured into it but wont idle, also a common problem is the coolant temp sensor and the ground wires to thermostat housing bolt but i wont bet its the pump inside the fuel tank, if you put a fuel gauge on it there should be at least 55-61 psi if its a few pounds lower it can cause problems, you have everything else and it runs with gas poured so its a fuel problem check the preasure, theres a valve up top on the fuel line to connect a fuel gauge to it, start there hope this is helpful.

Car dies on right turns, will restart, will not stay running


one of two things come to my mind in hearing this , 1st damaged inertia pump switch (this switch shuts off fuel pump in case of high Inertia-wreck) 2nd the fuel pick up or baffles inside fuel tank have broken off this will require the removal of the tank for a look at it

Check the rpm in neutral should be around 800-850, this should drop to 500-550 in drive or reverse.

I have a chevy 350 with two hollie carbs .how do i adjust the fuel in the fuel and air to make it run so i can ajusted it after i get it running


Well the correct way of doing it would be with a 4 gas analyzer but without that you would have to use a vac gauge.
Once you get it running and have the timing set, the carbs would be adjusted lean until the RPM and vac drops, then go rich a turn or so on the adjusting screws. Most Holley carbs start at one or two turns out.

It could be a combination of 2 things. A faulty MAP sensor itself or a bad TPS (throttle position sensor). It's not uncommon for a bad TPS to idle when the motor is cold but once warm, not idle fast enough to keep the vehicle running.

Runs ok when under 3000 revs, but try to accelerate & car just dies


Sounds like you are not getting enough fuel or air. Either your fuel filter is plugged, air cleaner is plugged, (I'd start there--least expensive), or your fuel pump is going bad and when you step on the gas pedal and call for more gas, the fuel pump can't keep up with how much it needs to open the fuel injectors. But start with taking the air cleaner out and cleaning it or replacing it.

2000 Malibu will not idle


4000 rpm and flucuating is normal. rpm limiter. If its too rich need to find out why. first thing to check is the fuel pressure regualtor, take off the vac hose to it, and if there is fuel in the hose, the regulator is bad and will need replacement. that is only 1 thing that could cause rich running but is always the first thing to check. if its running that bad there should be a service eng soon light on.
