Bad O2 sensor(s) won't cause significant loss of power. restriction with gas flow (filter, pump) or exhaust (catalytic converter) most definitely can.

I just changed the driver side CV joint and all of the manual transmission fluid came out. Where is the filler hole on the manual transmission?

the speeometer drive is removed ( it's a senser) the gear on the senser has a fill mark on it and the oil is filled to the mark though the hole where the drive was removed. It uses GL4 75W90 Gear oil.

Location of oxygen sensors on 2002 dodge grand caravan with 3.3 liter engine after considerable maintance work done by a dodge dealer my gas mileage dropped by as much as 6 to 8 miles per gal. after a time...

The o2 sensors are located on the exhaust system.The upstream in on the rear exhaust manifold and the down stream is in front of the catalytic converter.Usually when they are bad they will make the check engine like go on.Make sure the air filter is clean,tires at correct inflation,alignment is to specs.If the vehicles pulls to one side or the other or steering wheel is not straight when driving down a straight stretch of road.Also tires are wearing normal.Use cruise control where ever on highway.If you let your vehicle warm up in winter.This also uses gas.Hope this helps.Good luck.

I have a ford zx2 it runs good untill i am idleing then it runs really rough. I was told it could be crank senser or oxygen senser

doubt it'll be the oxygen sensor since that would trigger a check engine light.

It'll either be your crank sensor, or egr valve

Engine problem i think?

when a oxygen sensor is bad it shows and acts as if there is problem somewhere in the car. even though you had the O2 censor changed there is still a chance that when they ordered and installed it that it was defected. yeah its stupid but that was what i was told by a mechanic. but thats what that sounds like or maybe transmission.
