It's a MY2000 C280(w202). The car is rough idling and there is a loss of power. Check engine light is on as well. I am pretty sure its spark plugs wires.

I have never bought any parts online. Anyone can recommend me a good source for spark plug wires?

also do you think I should replace spark plugs and coils while I am at it? I replaced my spak plugs with bosch platinum(or whatever the best one is) about 45k miles ago.

thanks in advance

AutohausAZ.com is an excellent source for MBZ parts. Try the plugs and wires first before you spend the money on coils etc

Substance If im not mistaken you shouldnt use platinum spark plug, i saw alot of thread W202 can only take Copper spark plug. Anything other then that will cause problem.

Look if you going to spend big money for wires(as you know) do like I did. I went to eBay and bought a set for $115 dollars and have had them on for over 4 years now. Do the plugs...use anti seize and be sure to use boot lube too. There is nothing wrong witht the eBay wires for the price they served me excellant. Look $115 0r $500 you decide.

I replaced the spark plug wires. I unplugged the battery for a moment to reset the check engine light. Car ran fine for a few minutes then check engine light came off again. The car drives normal now.there is not loss of power anymore. I drove it around. The engine rough idles sometimes when I come to a stop but not everytime. So it is defi.itely improved but not totaly fixed. What do you think is causing check engine light and rough idle?

Do I really need to take it to a dealer to get this reset? Do you think one of the wires is loose?

I dont have a code reader. Can autozone read mb codes?

Ok autozone can read codes for this car. Or any obd2 reader. Its cylinder 1 misfiring. I bought 12 sparkplugand replaced them all.problem solved.no more ceheck engine.
