Hello! Sounds like a defective Throttle Positioning Sensor (TPS)...Bolted to the throttle body with a four wire connector...(one lead for the air flow meter)...We are interested in three of those wires...Wire colors are: Brown/Black=ground...Green/White=output...Green/Black=5 volts...
Using two safety pins push the points into the rear of the in-place connector into the Brown/Black and Green/White wires...Clip the (+) probe of the meter set to read 5 volts to the Green/White pin and the (-) probe to the Brown/Black pin...Start the engine...At idle meter must read less than 1 volt (.85)...As you increase the throttle the voltage must rise smoothly to 4.5 volts at full throttle...If it does not the TPS needs to be replaced...See photo below...Guru...saailer

Van running like its missing


the problem is not in the plugs , wires , cap , rotor but in dirty injectors or injector controls and wires
use a quality injector cleaner for a few tanks of fuel
ECM controlled cars do not a tune up as the computer does that 60 times a minute so all you need to do is to run the fault codes and fix the faulty sensors
fault codes are being recorded all the time and only the serious engine or transmission faults put the engine light on

Missing


engine missing could be caused by faulty spark plugs and wires,bad ignition coils,dirty fuel injectors,leaking egr valve,low cylinder compression,intake vacuum leaks.many things will cause engine to miss, first do minor fix,replace distributor cap and rotor,replace spark plugs and wires,clean fuel injectors,replace fuel filter and air filter,if this minor tune up dont help engine and engine still missing, do a vacuum test and compression test to check condition of engine.engine could be worn out have low compression by worn valves and pistons rings.

Your misfire can be cause by couple of things but the cheapest way that you can try to fix your car is to do a tune up by replacing:
1)all spark plugs
2)do a oil change
3)spark plug wires
3)distributor cap and rotor

note misfire can be cause by:
1.bad gas
2.spark plug and/or wire
3.distributor cap and/or rotor
4.valve adjustment
5.injector
6.off timing
7.ECM
8.bad wiring(power, ground or feed line)

2004 Silverado 4.3 V6 Has miss on cylinders 2 and 4. Have done complete tune up Plugs Wires Cap Rotor,Fuel Filter. Still had Miss. Compression on all 6 within 8 lbs of each other. lowest reading 168...


Check engine light on? Any codes? Missed before and after the cap was changed? Or is the cap new so you assume its good. I have had caps bad out of the box.

I am having the same problem.... Same car.. I replased all injectors,wires,plugs,dist. Cap and rotor. Pcv valve... Egr valve is good.. it runs great then starts missing bad,fuel smell out the tail pipe and it smokes.... Then it'll clear up for a bit or even a while the it repeats it self... And it seems to me like a sensor or something eletrical is causing the sudden miss and fuel problem.. but I'm lost... I don't know what else to do..
