Hey,
I have a 2003 sonata with the 2.4 in it.
The car has been sputtering for a couple seconds randomly, then goes back to running fine. The interval of this happening was once every week - 2 weeks.
Never stalled the car just seemed like a shudder. It just started doing that 4 days ago and didn't stop. The car has no power, misfires and backfires while put into drive or reverse. Opened everything up to check timing. Replaced the Crank position sensor, camshaft position sensor, timing belt, timing belt tensioner, both coil packs. Checked pulse for injectors ( they all fire) The plugs seem to be a bit damp and black. They're all brand new plugs as of 24 hours ago. I have spark. I can't seem to figure this out. When i unplug the Camshaft Position Sensor and start the car it starts up fine, no misfires or anything. And then cuts out within 3-5 seconds. Plugged back in, it barely idles. Pops misfires backfires. Any ideas im desperate!!!
