April 24, 2004Vehicle is 00 EB 5.5L w/94K miles.
Changed plugs (what a pain in the ass, BTW...) and it was running perfect for a couple of days. Now the misfire is back again and even worse than it was before.
It also threw a SES light. Plus now it even has a weird smell outside. Haven't taken it to AutoZone to have the code read yet, but I'll post the code once I get it.
Any ideas? Runs fine for a couple of days but then comes back, is worse and even throws the SES...
Haven't changed the fuel filter yet (will do it tomorrow). How about PCV valve...? EGR...?
Thanks in advance for all your help, guys!
