2003 VW Passat B5.5 2.8L GLS wagon FWD
Discussion Starter · #1 ·
Hey guys, new to the site here, I bought a B5 2.8 wagon about 6 months ago, just a few days ago I fired it up in the morning and it started idling real rough, then flashed a CEL at me, I shut the car off, plugged into it and got some P0300 codes, misfires on multiple cylinders. I cleared the codes and then started it again, rough idle is gone. Since then I’ve done this a couple more times to verify that it is indeed only on the first cold start after sitting for a while that it runs rough. I just replaced the plugs tonight, to no avail, I’ve read a couple threads on here with similar issues, hearing a lot of MAF talk, so I will be pulling that apart and cleaning it in the morning, but I wanted to go ahead and post this to see if any of you guys might have this experience with your cars and could point me in the right direction, thanks in advance!
