If it was an Oxygen sensor it would most likely cause the CHECK ENGINE LIGHT to come on.
I would check the spatk plugs and condition of the plug wires first.

    check fuel presser. if car sttays running long enought,tap lightly on mass air flow sencer...if it stalls,could be it ,wet spark wireslook for sparks jumping. is there a buzzing noise when running in the car? thats the fuel pump....with a gage turn on car,not running and read it. should read 50lbs i think. start car ,should read the same. shut off car gage should very slowly drop. again VERY SLOWLY DROP. how old is fuel filter? check engine light on?

2000 ford taurus keeps blowing fuse#28 in the engine compartment


The heading says2000 taurus and 1999 taurus. I looked up the wiring for a 1999 taurus. Fuse #28 goes to the heated oxygen sensors and the canister vent solenoid. You have 2 oxygen sensors (green connectors)and 2 catalist monitors(blue connectors) that use this fuse for the heaters that are in the sensors. I would check these sensors to see if any of their wiring is shorted. I have seen in the past where oxygen sensor wiring would rub on a front drive axel and wear thru the wire insulation causing a short. You really need to look at all 4 sensors and their wiring closely for shorts. If they look ok then disconnect all of them and reconnect 1 by 1 until fuse blows again. Fuse #28 also powers the canister vent solenoid which is located under the trunk (under the car) in a black plastic housing (approx 1ft by 1ft). It is the only item with wires going to it. If you disconnect this and the fuse stops blowing then it is shorted. Also check the wiring to see if it rubs or is shorted anywhere.
Hope this helps

I have a 1999 oldsmobile intrigue that is misting a lot. It idels rough, and runs rough. I can still take off it is a little slow, but I can still go pretty fast, but it still mist at the high speeds...


fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck
