oxygen sensor,gm crossover?

[senna01]

i was wondering if anyone knows what gm part number will crossover for an oxygen sensor in a 94 s4?the reason i ask this is because i just had my esprit fully serviced,all new belts,green dot cam sprocket,updated chargecooler pump,valve adjustment and k&n air filter,still waiting for my stebro dual tip exhaust and cat pipe after three weeks but thats another story!but i degress,my car seems to idle rough,not a misfire,as the engine is in great shape great compression and very clean inside,pulls like a train,but it seems to idle roughly,i thought the service might help btw new ngks too,but it has not,also the check engine light does not come on at all when the car is running,so i think maybe the o2 sensor is getting weak,i know this is rambling but any help would be great,thank you.

Here's two listed from Dr. Hess's site. Can't vouch for the validity, YMMV....


Oxygen Sensor Bosch 0 258 003 022 Exact replacement
Oxygen Sensor AC Delco 16054

That AC Delco is a good number, at least for an 89 non-SE. It is the one that came on my car and is still there. The thing that worries me, though is that it also is marked "Experimental" and I haven't seen a cross to anything else. Who ever heard of a production car coming with parts marked "Experimental"? I'd try the Bosch number given by Kenneth Golden, which if I recall even has the right plug on it. You can also look at the one in your car now and see what kind it is and the number.

One way to test your O2 sensor is to record a Freescan log and look at the rate and magnitude of the voltage oscillations. At least one owner in the UK has had problems buying a generic O2 sensor that was supposed to be a cross reference.

Must be from the same Website that lists the Brake Pads with No Adjustment Pins...
