93CutlassSupreme Posted November 19, 2003 Report Share Posted November 19, 2003 when you rock a 3.1 foreword to get access to the rear plugs or O2 sensor, do you really have to unbolt and put the coolant tank out of the way? my exhaust smells like ass when the engine is cold and i think the O2 sensor is bad and i want to change it. Or can i forgoe rocking the engine foreword and get to the O2 sensor from under the car? thanks for any help Quote Link to comment Share on other sites More sharing options...

Dannymik Posted November 19, 2003 Report Share Posted November 19, 2003 whats the reason your replacing the O2 sensor? Stalling or running too rich? Quote Link to comment Share on other sites More sharing options...
93CutlassSupreme Posted November 19, 2003 Author Report Share Posted November 19, 2003 every now and then the car stalls at idle in gear, the rpms bounce up and down, almost to zero and then up to a grand, almost like the engine is trying to catch itself, this doesn't happen much and the engine starts right up. that could be a egr or a pcv or a idle speed sensor problem or an o2 sensor problem. i am just tired of my exhaust smelling like ass when i start the car up when it is cold i'd rather try to change the o2 sensor and see if that solves it instead of buying a new cat.....any input if changing the o2 or any other sensors will sove either of these two problems?

91cutty Posted November 19, 2003 Report Share Posted November 19, 2003 every now and then the car stalls at idle in gear, the rpms bounce up and down, almost to zero and then up to a grand, almost like the engine is trying to catch itself, try an idle re-learn. My car car did that and the idle relearn fixed it right away. Star car, idle for 10 mins in OD with foot on brake, shut off car, wait about 30 seconds, restart car, idle in OD for 5 mins, DONE!

That's something you really can't change. The catalytic convertor needs to warm up to fully convert all the combustion products from the exhaust. You can install a new cat, but I don't think that will improve the situtation by much. - Erik Quote Link to comment Share on other sites More sharing options...

mdelorie Posted November 19, 2003 Report Share Posted November 19, 2003 I don't quite understand the bad smell that he's talking about. my car doesn't even have a cat, and it smells fine. :?: Quote Link to comment Share on other sites More sharing options...
93CutlassSupreme Posted November 20, 2003 Author Report Share Posted November 20, 2003 you really can't describe a smell with words......there's just a strange odor coming from the exhaust when the outside temp is cold.......maybe the car is running rich at cold temperatures Quote Link to comment Share on other sites More sharing options...
91cutty Posted November 20, 2003 Report Share Posted November 20, 2003 does the car kinda smell like half-way between a burning match and rotten eggs? If so... clogged cat! Quote Link to comment Share on other sites More sharing options...
