i dont have an oxygen sensor on my 1987 3.2
i was looking for the oxygen sensor to see if it is ok and whether it has anything to do with my fluctuating idle car is a 1987 3.2 carrera and i cant find an oxygen sensor anywhere

Your O2 sensor should be screwed into the forward portion of your cat/bypass pipe/euro pre-muffler. It may have a stainless steel semi-circle shield around it. Otherwise, you either have a Euro engine or an engine that the prior owner deleted the O2 sensor.
What is the type number (i.e. 930/21) or serial number of your engine?

That really doesn't help; just means you have either a 1987 Type 930/20 or 930/25 engine.
If you can not find the O2 sensor on the cat, then you probably do not have one. Do you have an O2 sensor plug inside the engine compartment (left bulkhead below the fuel filter)?

ok had a look today and it definetly has no oxygen sensor any idea why this is and how is all the fuelling controlled
i need to check the fuel mixtures how can i do this as i need to put the probe before the cat will this car have a cat
i basically have an idle problem keeps fluctuating from 800 to 1200 i have checked the air flow meter/sensor, idle air control valve, throttle position switch and sensor i had to adjust this , speed sensor, cranck sensor,checked for air leaks, cleaned the throttle out but still cant sort the idle.
all the sensors were checked using resitance

I run an APE chip and a test pipe, my O2 sensor is installed on the test pipe, but it is disconnected at the wiring connector in the engine compartment. This just causes a rich running condition.

I don't have an answer for your O2 sensor question, but among the list of things you checked regarding the idle issue, I did not see the idle switch. Sometimes they need adjusting or they can go bad, either case can result a in fluctuating ilde.
Good Luck

is the idle switch seperate to the throttle position sensor i tested the tps and on top of this was another sensor which i tested and was fine this isnt the idle switch you are referring to is it, if i pull the connector of this the idle goes uo to around 3500 revs and stays constant

The idle switch is located on the back left side of the throttle body. The connector for it is located on the right front next to the TPS connector. It sounds like you checked it.

checked the co today it was .25 and HC 1500 the car started popping on idle a bang after 10-20 secs managed to stop this by adjusting screw back to 0.28% didnt want to mess about any further problem now is car seems its running on 5 cylinders has lost power and feels rough like a slight vibration through the car
