Message:
ok..im very new to this site so bare with me. I
have a 2004 3.7l 4x4 club cab. the problem im
having is just after replacing the plugs, i found
the truck starting to run a little different-rough
idle,studder while at low rpms...ect. the Bosch
platinum +2 that were in it came out with a red
color. so in otherwords its running pig rich! my
question is what the hell would cause that?? im no
mechanic but even i know fairly new premium spark
plugs shouldn't look like that with only 75,000
miles on the truck and at the most 5000 miles on
plugs. please help...very impressed with this site
too!! thank you to whoever can help
