I don't even have my O2 sensors plugged in N my car does just fine, but I don't know if it would effect his car.

vacuum leak?

I dont think its a vacum leak because it doesnt always do it. It will run fine then do it and then go away. I think ilif I had a vacum leak it would be consistent right?

Mine did the same thing, I was told that he iac was bad or needed to be cleaned. I haven't done it myself, since the car hasn't done that in a while...

Also mine had a very rough idle after it cooled down for a while. But hasn't done that yet for a while now.

Does your speedometer work? 94-95s will also do that if o2s do not work.

Ya the speedo works but the mileage trip dont. Im going to buy a new iac value and see if that helps. I cleaned the maf and throttle body so far. One o2 sensor was now hooked up because it was the wrong one so I bought one and still the same thing
