I have a 2004 dodge dakota and i think my crank shaft sensor is bad, because when i go to start it have to pump the gas to get it firing, also when i am just sitting still i can only rev it up to 2000rpms before it over revs, and when i drive it up the road it jerks from over reving to soon. so i need some help am i correct about my problem if not what might it be?
If the crank sensor fails it will probably stop the engine. I have known a diesel engine continue running with a failed crank sensor but it was virtually undriveable and sounded really rough.
Pumping the loud pedal isn't likely to be very helpful whatever is wrong. Pedal pumping is for older cars with a carburettor that isn't in good order.
The best help will be from a guy with a scanner...

Its your Idle speed valve. PCS (part supplier) quoted me £45 + vat for the part. Easy fit but I paid a mate £10 to do it for me
hope that helps

if battery is weak the idle air control solenoid will search for the right position and stall have battery load tested if good put in a idle air control solenoid..

you need to ck some basics you could have a vacuum leak which would hide during warm up but cause havoc when hot,the leak would cause high idle then your pcm would try to lower idle to spec thru use of idle control motor causing surging idle ,also fuel pressure needs to be checked while acting up,may be more cost effective to pay for an hour of diagnostic.

You may need a transmission flush, if one of the valves sticks in the transmission it may not make a quick decision to shift when in between gears. Worst case ...this may be a precursor to worse problems, like a transmission rebuild.
