ight so like the title says both tachs bounce. mostly during downshifting but will do it will cruising. the speedo will bounce any were between 10 and 20 mph and the temp guage will just keep taping out. i think it might be the ignitor coil but just wanted to see if anyone has seen this and knows what it is. the car is a 94 hatch with a 95 h22 type s. no codes are being thrown.

 

i would find another cluster in the yard and try it. it could just fix the problem. i see alot of dc2's in the yards now that they are getting old.

 

Probably the plug in the back of the cluster.
