I have a 95 Ford Probe, after it's been warmed up a bit, I notice at a stop that the idle drops down so low I think the car will stall, I have had a major tune up, I have replaced the Mass air flow Sensor, I have had it in the Ford shop 4 times and it is still doing this. Could it be the 02 sensor?
Thank you

I have the exact same problem with my Probe. Would it be worthwhile to change the O2 sensor?

There is a tech bulliten on 93-96 Probes, cure is fix all vacuum leaks, then if not cured replace MAF sensor with the revised part...

get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs!
