HELP, I jusy got my subie and while I was wiring the turbo timer to the ecu I notived a **** load of electrical tape on alot of the wires. some one had some **** in my care and I dont know what it was. Im throwing the check engine light for the o2 sensor bank one sensor 2. I researched the net and found several problems. The first was a jumper wire between the blue and white wire on the sensor wire its self. next was a exaust leak on the stock exausts manifuld. I fixed both problems and Im still throwing the check engine light. Im now trying the ecu reset but its raining and I have a cold air intake. So Im not going to be able to take it to redline. Also Ive heard that a intake without tunning is bad. Should I take it out? Will it hurt my car? talk to me!!!
