Chevrolet k1500 silverado 2000 stalls when you first take off, per autozone, I replaced the plugs, and wires, cleaned the main air intake sensor and then replaced it, changed the 2 front o2 sensors, nothing seems to help, we did get codes that said bank 1 and 2 were to rich and tried everything it suggested, still have the problem, even ran some sea foam through it to get the carbon out, no help

the fuel sender unit
is for the gauge to read quantity in tank and is usually incorperated in the pump unit ,when it stalls does it start straight away again ?its more likely to be related to air/fuel , spark ,vacuum at the engine so i'd do a few basic checks there ie air intake pipe not collapsing , air filter ,plugs , vacuum pipes etc are in good condition , also fuel pump relay may be breaking down , as you see there are a few things it could be , the OBD may give you a clue so have that read but pre1996 vehicles this was pretty basic and would need a mechanic with the right reader to do this or log onto a chevvy forum as these places are full of knowledge specific to chevvy, good luck

REPLACE AIR FILTER,CHANGE SPARK PLUGS AND WIRES.CLEAN FUEL INJECTORS.THEY COULD BE LEAKING FLOODING ENGINE FOULING OUT SPARK PLUGS.

Problems mass air flow sensor, fuel pressure valve, fuel pump

Intake gaskets will **** air when cold and cooler weather causing a skip when first start up. this sounds like your problem

There are several parts which control the idle. One part is called an "ISO" motor and it is suppose to regulate the air flow and fuel mix for the engine. This part is probably dirty or worn. Another part is the TPS throttle position sensor which regulates the fuel and spark timing settings.

Even if the "Check Engine" light is not on, there are sometimes codes stored in the onboard computer. You can get a free scan at Autozone or Oreillys and it may tell you which part is bad. The main problem with diagnosing both of these parts is they are variable and not Off/On type switches. Your problems occur when the variable setting is wrong for the moment and not a complete failure.

The plugs are under the air intake manifold. Disassembly is easier because the water system is now separate from the air intake manifold. There was a problem with sparkplugs breaking into 2 pieces on removal. Plugs are rumored to be good for 100,000 miles per the manufacturer.

it should but recheck ur wires and plugs first a bad plug or wire can cause a knock ping problem and set off sensor also check the knock sensor connections at rear of engine----- the knock sensors for the 8 cyl are located under the intake manifold so its labor intensive to replace the sensor

First, you have to remove the intake manifold and all associated wires and hoses. Once the intake is off, you will see two rubber plugs in the middle of the valley cover. Pull up on these plugs, so that you expose the connectors, and remove the connectors. You then will be able to unscrew the sensors using a ratchet, socket, and extensions. Replacement is opposite of removal.

sounds like the idle air is gone

the intake sensor is located in the intake hose between the air filter housing and the engine. small, 2 wires.

Try replacing the coolant temperature sensor for the injection system.
