At that mileage it could be anything from plugs, to clogged injectors, to tensioners (serpentine belt and/or timing chain), to sensors, etc. Need to find out what codes are being thrown by ECM before proper diagnosis can be given.My Sonata has 150k on it and the tensioners have gone bad 3 months now. This AM i got a flashing check eng. light and the car runs rough. Any relation or am I looking at plugs or coil issues? Any help ia appreciated!
The Timing Chain tensioner on many early units were defective and had to be replaced under a service campaign.thanks - figured as much. Just went for a spin and it's fine now. weird

Did you have it scanned to know which of over 120+ codes you might have ?
Any relation or am I looking at plugs or coil issues?
Did you replace the IRIDIUM plugs at about the 100,000 mile mark ? Scan it and see what the PCM has determined the problem circuit(s) to be, then go from there.
Any help ia appreciated!

Auto zone, advance auto or most auto parts store will scan for free. Make sure you get the actual code #, not just what they interpret it to be.Thanks, no scan yet - as I said earlier though it did clear up and no flashing light. I will get it scanned though.
