1999 i30 idle and throttle problems

[evmal613]

Hey guys,

I have an 1999 i30 thats having some issues. The idle/throttle fluctuates causing hard jerks and engine lights on. I have a feeling its a fuel problem, The injectors have been cleaned, just replaced the fuel filter, Just seafoamed the car. Im somewhat running out of ideas.

Thanks

If the check engine light is on, have the car checked for codes. That'll give you an idea of where to start.
