Will not run pass 2000 rpm

Make sure it's in park. If the key still won't remove try turning the steering wheel to get the key to turn. Running out of gas cannot cause a key issue. Two unrelated vehicle systems.

There can be more than one sensor in the system. But here is what happens when your old sensor goes bad. The fuel mix can go rich and this results in a buildup of soot in the catalytic converter.

Sometimes the catalytic converter can recover over time. There are cheater additives which go in the gas and may help you pass the test.

You need a better diagnosis of your potential problem. The onboard computer in your van will not Code every problem and has to be showing a "check engine" light to display any problem.

However, better Scanners (Some costing thousands) can probe the system and reveal many defects.

New sparkplugs, clean fuel injectors, can help lower emissions. Just remember that an additive which dissolves debris on fuel injectors can also send that debris to your Catalytic converter.

Now as far as running it "forever", you want highway speeds, which in terms of RPM is about 2000 RPM on many vehicles. You can shift out of "overdrive" and this will keep the RPM higher at a slower speed, but it needs to be above 45mph to be effective. Your overdrive does not always kick in below 45, so to make a difference using my tip would require driving above 45.

Doubt it had anything to do with the oil change or belts replacement unless they were done wrong. e.g. improper oil or belt placement. Sputtering, as you stated usually comes from the fuel system. Check that.

If the RPM is higher at any particular speed than before, the only cause could be that the transmission is slipping. Things like O2 sensors, Catalytic converters, fuel treatments, etc. have absolutely nothing to do with incresed engine (input) speed to axle (output) speed ratios.

buy some injector cleaner and add to you fuel tank
maybe some gass line antifreeze aka methal hydrate

possibly the fuel pump check the fuel pressure with a gauge on the fuel rail if its a gas motor, is it diesel if so your in luck cause im a diesel mechanic

Are you consider yourself a handy person?

Swap the coil and see is the misfire going to follow to another bank of cylinder.

You has total of 3 coil in your engine.

Do a detail record map and switch the two coils.

A replacement aftermarket coil is oil $46 w/one year warranty and $55 will get you a life time warrent coil.

Do the swap and see what happen.

A leaky/failing injector can also cause the same problem.


Do a Chevron Techron fuel injector clean ran and highway ran.

Good luck

check your fuel filter and make sure it not plugged up, make sure you reinstall exactly as it came off.
good luck

If the Cylinder has that much fuel in it you probally have a stuck open fuel injector in that cyclinder.As far as the compression,you should have at least 125psi on the low end of the scale.hope this helps

The injector rail needs to be removed and water cleaned out have you done this? water will puddle up and cant pass thru injectors
