You are going to have to repeat diagnostics. Were there any other codes besides o2 sensor when first problem happened? (o2 sensor often comes up but is not the cause but rather the result of another problem IE: a fuel or ignition problem will change exhaust gas composition triggering o2 sensor code that code is there not because the sensor is bad, but because the conditions which it is "reading" are far out of range. Check for proper spark, proper fuel pressure and volume etc. before buying anything! Check fuel pressure regulator as well as crank and cam sensors especially.Pay attention to colour of smoke: was it black or white? Was engine temp normal? Overall, just check everything 'till you "zone in" on which system isn't functioning properly!!!I know it's not an easy fix, but I'm saying is exactly what any tech would need to do!
good luck!!

sounds like someone has pushed a plastic lunch bag in your fuel tank . This will cause the fuel flow to be restricted when the bag is sucked over the fuel pickup , then when you shut off the engine the bag floats away , only to start the cycle again when you drive it next . Good Luck

First of all, If you recently bought gas from a place you've never been to before, drain out the old gas, and put in a fresh tank from somewhere you trust. You may have water in the tank. After that, if that doesn't solve the problem, or you trust the place you bought from, go ahead and check all your external gas filters. If that doesn't solve it, I think that's when you're right: It's either the fuel pump, or the fuel filter, and in modern vehicles, both are in the gas tank, and both are very difficult to get at.

It sounds like you may have a bad connection somewhere. Start with your battery cables and then look at all of your ground wires as well. When you try to start your jeep see if the wires from the battery get hot.

Jeep wont start checked connection and fuses


Check the battery, it sounds like it's flat. Try charging the battery to see if it recovers, but if the battery is about 3 years old or more it is likely to have failed and replacement is the only viable solution.

1999 suzuki esteem, loses power, spudders, shudders, wont go


It might be that your spark plug wires are leaking current. The current that is supposed to go to your plug is going to the engine block or other wires. Start your car and open the hood in a dark place and look for little sparks coming from the outside of your wires. Replace if you see any.

O2 sensors are going to set off your trouble light if they are giving you trouble. So will a dirty EGR valve (after fifty miles of dirtiness).
