The first thing I would do for multiple misfire codes is clean the MAF. The oil likes to leak around the chain tensioner and around the timing cover. Check for visual leaks on the front and back of the motor. A quart of oil burning every 5000 miles is not much at all.

I had the exact same problem at our car dealership today with 2! yes that's TWO 2003 Black 1.8 turbo Jettas at the exact same time! wierd huh? maybe something to do with the warm weather. Anyway we solved the problem in both cars by replacing the ignition coils which were surprisingly inexpensive and the guys at the dealer say they sell alot of them because it's such a common thing to fail. we paid $38.50 a piece here in california from the dealer. No more problem with the codes or the cars running like ****. Probably the eaasiest parts on the car to change too. I changed all of them in about 30 minutes with a few simple tools.

Getting codes P0341, p0300, p0301, p0302, p0303


P0300 is multiple misfire. The corrective action for this code would be to test your fuel pressure and the injectors. P0301, P0302, P0303 is saying in certain cylinders there is a misfire. There are two different engines so I wasn't sure which one you have and couldn't give you the correct testing procedures for the coils. P0341 is saying the camshaft position sensor readings are bad. Again I am unable to give you the correct tests to check this due to not knowing your engine size. Feel free to email me at csautomotivecars@att.net with detailed information about your vehicle and I will be happy to email you the testing procedures to narrow down the problem and help you solve it.

I would check out the EGR valve. That maybe what is causing all the misfires.
