Hi


Thanks for using FixYa. The check engine light is on because ECM (Control Module) detected a fault with your car's system. ECM has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" light to tell you that there is a problem and your car needs to be looked at. The fault code is known as an "OBD2" fault, it seems that you are right that the oxygen sensor needs to be replaced. Please do accept the solution if the issue is resolved or post a comment for further assistance.

Thanks
Rylee

Does the driving on overdrive mode cause high fuel consumption, because the transmission use the first three ratios mostly?


driving in over drive mode actually is what gives the economy as the engine rpms will be around 300 less than direct drive . Lower rpms = fuel savings
OD should come in around 60 klm/hr and drop out at around 50 klm/hr. When you are accelerating hold the pedal in a set position and watch the rev counter (rpms ) and each gear change you will see the rpms drop and then build back up as the vehicle speed increases At 100klm/hr the revs should be around 3200 rpms or less but if over ( say 3500 rpms) then may be the OD is not coming in. One way to test a box operation is to find a speed shop with a dynomometer and test the gear selections against loads and engine rpms

The sweet smell is your engine coolant,check for a leak under the hood,look for green fluid,Have your catalyst checked,for the other problems,and your fuel presure checked,or change the fuel filter.Either of these should help a little.

96 Jeep Cherokee RPM Surge While Driving


If the problem began before you changed the plugs that they are likely OK...Some engines "like" certain brand plugs better than others. You may have a weak ignition coil. Poor spark will generally show up at higher rpm's. Spark should be blue and have good "snap" to it and should easily bridge a 1/4" gap or better. If fuel was contaminated, it should show up at lower rpm's as well. System cleaners sometimes work but often are added far too late to do any good. (tank can hold up to a gallon of water without noticing it.) I use 3oz of acetone and one oz marvel oil per 10 gallons of fuel about once a month...cheaper and more effective than most cleaners. (and does not "melt" gaskets and seals as legend has it) The vehicle speed sensor can also give you problems but needs testing to determine if it's got any problems.
It's difficult to diagnose by remote control, but I hope you benefit form something here!
