Ok my lil bro has a 94 integ LS w/gsr motor. Engine light is on so we check to see what it was. Threw code 5 which is map sensor. We went to dealership to buy new map sensor for GSR, put it on. Took off negative battery terminal for about a min put it back on, started the car and engine light still on and still throwing the same code. Anybody run into this problem or can anybody else think what could be wrong?

 

Could be the wrong plug, happened to me.

 

ahh i got it, i read the code wrong it's actually the 02 sensor
