I was reading online and saw 2 mechanics discussing a p0304 on a 2017 kia forte. My car is Exactly the same and is having the same problem. But in the reading, i was unable to see a fix. I've changed spark plugs, fuel injectors, swapped coil packs. Just took it to have it diagnosed at the shop and their as dumbfounded as me. Please help!
Describe the conditions under wfhich the misfire occurs. At idle, under load, cold , hot, intermittent or permanent. ....Please provide some data like fuel trims,freeze frame and any other codes etc.
An expert is someone who knows each time more on each time less, until he finally knows absolutely everything about absolutely nothing.
It's intermittent acne the only code is p0304. It's currently being diagnosed at a shop and they're going through forms as well. I've done spark plugs swaps coil pack swaps injectors swaps it did a compression reading yesterday everything is good across the cylinders. In the morning they're doing a cold smoke so I'm dropping my car off tonight. If you have any ideas as to what it could be I'd be greatly appreciative. I drive for Uber and can't drive right now so I'm hurting pretty bad. She it's a 6 speed manual. No gdi
The dealership performed that update last week and it was a Band-Aid for about 5 minutes. I've now got it at an import shop. They're going to take a look at it this will be the third diagnostic from a different shop.
