alright today i was driving around and accelerating into vtec ,but it didnt work
so i went to a parking lot got a spare piece of wire and got the codes
well they were code 15.....Ignition output signal .and 17.....VSS - speed sensor
alright a week ago i hooked up a autometer memory tach, about 3 days after hookup the tach has been jumping from idle to like 4k only when sitting and idleing
could that be the reason for the cel 15? i dont know about code 17
any help would be much appreciated
