2003 Hyundai Tiburon Q&A

2003 Hyundai Tiburon Question: My cylinders 1,3, and 5 are misfiring, what could cause this?

I'm driving along on the highway, I go to accelerate and my cars bogs out, completely stops at 4k rpms, can't push any further past it, I let off the gas, at this point my motor sounds like a go-cart engine, I push the gas again same problem...a test shows my oxygen sensors malfunctioning, cylinders 1,3, and 5 misfiring and a random misfire, what could cause all of 1 side to misfire? -
Answer 1
Have exhaust flow checked. Possible failed cat. converter. -
Comment 1
I only have 1 Cat. converter, could that still be the issue? -

Answer 3
It's not the Cat. If that engine has cam position sensors for each bank you may have one going bad. -
Comment 1
wouldn't that set off a different code though? -
Comment 2
Not necessarily. If the input side of the sensor is ok the computer can't tell it's bad, it sees the result which is the misfires. The CPS is just a guess mind you. I can't think of anything else that would only affect one bank, but I don't know that particular engine. If it's always running bad it could be that the timing belt jumped, but it sounds like it's an occasional issue. -
