3.3L Caravan runs on 2 cylinders ...

[Cobra_Sam]

Hi all,
I have had this one on before ... found no cure yet
1992 Caravan 3.3L 130k miles. Engine never used oil.
Here is my story and what all I have done so far. Traveling through a parking lot at 30mph she started to slow down to a halt with the engine running real rough (about 2 cylinder) Towed her home.
Here is a list of everything I have replaced and it still runs on 2 cylinders.
1. Fuel pump & fuel filter
2. Plugs and wires
3. Coil pack
4. Timing chain and gears
5. Camshaft sensor
6. Crank sensor
I have just disconnected the catylitic converter in case it was blocked.
She fires right up and runs on about 2 cylinders. Does anyone know what can cause this van to fire right up but not run on all cylinders ?

First off, Is the vehicle actually running on 2 cylinders or just sound like that. With that many miles you may want to have the fuel injectors cleaned. Clogged injectors can make an engine run really rough. Make sure when you have the injectors cleaned they actually pull the injectors. Some shops will just run some type of cleaner through the fuel system. This does not clean badly clogged injectors very well. You should also have the computer checked for error codes. Good luck.

When I start it I have to keep pushing the gas pedal down hard for the engine to keep running. Runs very rough (sounds like 2-3 cylinders)
