im having a problem i have a h22 in my civic hatch and whenever i drive the rpm gauge goes crazy it bounces up and down. i have tried changing the cluster and nothing the same thing happens. i have also checked all my grounds and they all seem to check out ok. what could the problem be. help!!!! this is aggrevating me

 

i have an internal coil will this cause any problems????

 

try checking your speed sensor...

 

usually this indicates the igniter is about to go out
