I recently fugded up an o2 sensor and had to borrow one from a friends 95 Del Sol-- now my car is running HELLA lean. Is this from the o2 Sensor, because my car is a 98?? I also didnt reset the ecu, would this help?? I just need to find out why i'm running hella lean!

 

if its 4 wire yes. 1 wire yes

 

Yes, that the 95 Del Sol o2 sensor is the problem?? and I should get an Integra sensor?

 

did the del sol 02 sensor just plug into the tegs plug in?
my 94 integra has a 4 wire 02 sensor, i dont know about the 98+ or even a del sol, but check the wires.
go and buy a universal one that fits an integra, they are like $30, splice the wires into your existing plug.
