ok i have a 91 crx si with a jet ecu and i'm driving along and my car all of the sudden the rpms will just jump around from 3 to 1 to 4 to 2 and it might die it might not, i checked the ecu code and it gave me 17 which is the vss veichle speed sensor so i took off my gage cluster and unpluged all that shit put it back together and the ecu stopped blinking the code but my car is still acting the same way, i changed my spark plugs put a new battery in, i'm puzzled please help me.
