I bought a 05 Tucson like 6 months ago. I replaced the TPS sensor because the car kept shutting off when driving. I also replaced all of the spark plugs the day I bought it because the vehicle had been setting and the spark plugs was old. Since I bought it I have been having trouble with some codes. I have codes for cylinder 1,3, and 5 misfires. Any advice on where to start to fix it? I have other codes as well.
the current codes for tonight are: p0463...p0174...p0420...p0325...p0173 plus the codes for the misfires

 

Some of those codes refer to the result of the misfires.

There are a few things going on and I believe it would be a good move to have a good shop with the right equip look into this further.

Sure you could start replacing a lot of parts ,but there is more here than just the parts you might be able to replace.
I believe there is some serious engine work required and best to have that verified by a competent shop.
