it is idling high to warm up.it is dying because the choke is shutting off before it has warmed up
A 1999 Chevy Express 3500 van that shuts off when it warms up can have a bad fuel pump. It can also be caused by the distributor cap getting worn out.
have a 89 Chevy astro van starts good till warms up the start to chock and then stalls
Tune up time with fuel and air filters, spark plugs and wires.
Grounding issue, bad wiring, failing bulb.
If you 4.3 liter begins to smoke as it warms up, it might have an oil leak that is causing the smoke. Often, the oil will leak once the engine reaches operating temperature and it thins. or it might be the valve seats going bad because my truck does the same thing and its the valve seats
Needs an ignition module
the oil pressure in the engine rises when the truck is warming up causing the light to show, if continues after the truck has been running, change oil and oil pump.
Connect a code scanner and see what the computer has stored. It will tell you exactly what to repair. have you checked your fuel filter? sounds like a carburetor problem
Auto-choke is stuck open
it may be the oil pressure sender located on the engine
It will get pushed out onto the ground as the engine warms up.
cracked heads or block
in my case it was a coolant sensorbut you really need to read the codes
after truck warms up will be hard to start,module may even start turning white colored make sure you are getting 12 volts to the module from the ignition also good luck
the first thing to check is the manifold air temperature sensor
your timing is to far advanced.. retared your timing and it should run like a raped ape
Turn on heat, on high till car warms up.let it cool down that may do the job... Check fuild.
The sun warms the earth.
The land warms faster
i have a 2000 dodge work van 318 engine when i start in the morning it stalls several times until it warms up then ok
Chev has a law suit on their small blocks from piston slap. Take your vehicle to a real DEALER and have them check the recal against your VIN #. This is a big problem for Chevy... the pistons are cam ground (not round) and expand to a circle in the bore as she warms up. The noise I suspect you are hearing is the famous piston slap that these units are getting known for. Go on some Cheby forums and I am sure you will find discussions on this issue. Hope that helps you --
Bi-metallic choke coil. pulls the choke open as the engine warms up.
check the egr vavle or the purge valve
in my case it was 7 dollars coolant sensor but read the codes could be any sensor failing
