my tach and my speedo are going all over the place, sometimes when i gas it the motor bogs, however the car idles fine. the motor doesn't rev just up the cluster, unless the rpm isn't at the right spot the motor is running fine. is this a dizzy problem??

b16a2 w/chipped p28 in a eh hatch

 

have you tried swapping ecu's?? ignitor about to take a crap?

 

check your engine bay harness. it may of came loose? its located on the t-stat housing its 2 ground wires w/ a 10mm bolt. it would cause all your problems

 

btw thats 1 hour worth of diag time so..... $70 please j/k

 

Doubt this is your problem but my car did that when the alternator was dying

 

checked grounds they are fine, gonna bring it into the shop but u guys dont think its the dizzy?
