thats fine but after i replaced the plugs and cleared the codes ,i did a test drive and it ran fine . then i went on the expressway and accelerated
and i was going no where .. i was loosing speed . then i eased up on the accelerator and took off slow . a few more times of fast acceleration and
ck engine light and vsc light came on . this time i had codes po301,po302 and po304 . i don't think coils are the problem ! it lacks
any power on acceleration . and it happens after 30 or 40 mph .
computer flashes need done ???
