Highway Jerking My van wants to stall whenever I'm in the highway for about 20 minutes. It starts jerking and it feels like it's about to turn off, then I press the gas and it turns back on, or it seems like it does. Then it does it again about a minute later.

cracked fuel line sucking air bubbles? i have the same problem right now with my 85 ram and am about to replace the rubber lines out of desparation.

SOURCE: Engine runs rough after about ten minutes /idles really low

Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

I had a similar problem with a dodge intreped after about 300 dollars I found out it was the oil sending unit was bad on my car it would go into a safety shutdown when the oil sending unit sent a faulty signal to the computer

If it works well at speed and acts up when slowing or stopped it doesn't sound like fuel filter or pump. You can try running injector cleaner through the engine to clean the carborator injectors or fuel injectors if you have those. Look at replacing the plugs and wires on the motor.

First thing, and it costs nothing, is clean the throttle body interior thoroughly. Lift the throttle plate with your fingers and make that interior spotless, pay special attention to the rim of the throttle plate too. OK check out how it runs. If the problem is still there have a garage or Autozone do a code read from on the on-board diagnostics (OBD). If the car is exhibiting rough engine running I would check spark plug condition and the efficiency of the spark plug holders/leads. If when the car stalls does it start up directly or is it reluctant. If the former, change the cam sensor and if the latter, change the crank sensor. Both sensors when faulty also give rise to intermittent misfire events. At the age of your vehicle I would replace both as an insurance policy as they both have finite life. If no codes show on OBD replace the O2 sensor on the exhaust manifold. O2 sensors deteriorate with age and often give problems before the on OBD can detect them. The fact that you have a CEL also indicates an emission fault which points to an O2 sensor signal outside of normal range.
