my obd2 is throwin out knock sensor code, o2 sensor code, idle air control valve code, and electrical load detector code.....im THINKIN the p28 is gonna take away the knock, o2 , and MAYBE the iacv......what do u guys think

codes 14, 41, 23, and 20

 

?

 

if you go obd1 p28, you knock sensor and 2ndary o2 sensor code should go away. but since you're running a b18c, you'll loose control of the iab

 

hmm i was throwing a knock sensor code as well and all i did was tightened it because it was a little loose. But its worth a try to go to a obdI ecu.

 

if you get chipped p28 it will eliminate knock sensor, 2nd o2 sensor, eld i believe is in the dist.
