i am first owner of 98 infiniti i30. it has 147k miles on it but its been sluggish lately. when i got SES light on 2 years ago, I ended up replacing:
- spark plugs (all 6…NGK platinum)
- ignition coils (all 6. this was the one that caused SES light to go on)
- knock sensor
- drive belts
its not at all smooth when i give it gas. i can feel like sort of drag or whatever. am getting around 22 mpg on highway. it used to give 28 mpg before all this mess.
if there is good mechanic who knows these in detail i’d love to let him fix this. don’t want to get ripped off by dealer.
i live near san jose, ca. i think this car still has good life in it.
