i have a 93 Si with a b16a2. my rpm guage reads zero but my car doesnt die out. i have no idea what the problem could be. any suggestions?

 

Make sure your blue rpm wire from the dizzy is wired up properly through to the cluster.

Does the car run like **** or is it just not displaying?

 

my rpm guage works and stuff, just at an idle t reads zero...it runs fine, but i notice that my rpm guage is off by 2 or 3 hundred...i have a b16 with a p72 ecu...stock rev limit, but on the guage it cuts off around 7700/7800...
