Well I was going down the highway all of a sudden I felt mycar get weak and I got home my motor was shaking like if the idle was too low but it wasnt .So at the moment I needed to take my car to the emision so I did.The guy in the emision told me their was no way my o2 sensor could be working but their was no check engine light.At home I said to my self let me disconnect my o2 sensor to see how the car reacts when its turned on the same thing but only the check engine light turned on.So shouldnt my car act different if my sensor disconects well let me know any other things that could be it because this sensor cost $150 at my local auto parts its not that im trying to be cheap but their are other things I can do with $150.

 

OBD-I or II?

 

its a obd1 95 integra ls

 

did you check your pcv valve... or ur tps or iacv?? i dunno just other options besides o2 sensors... good luck

 

well my 95 LS had an O2 sensor problem, but mine had problems revving. At idle it did what yours is currently doing. I had a loose wire on the O2 sensor that connects into the header. The loose wire also affected the TSP. Once I fixed that wire it stop. I also didn't get a CEL during the whole issue. So I would check the wiring, make sure there's no damage to them or the harness.

 

Yeah my car has problems reving up too.
