I had a misfire at idle. I know it's the #6 cylinder. Pulled a plug wire and have spark but idle doesn't change when #6 is pulled. All others have a noticeable drop in RPM when their wire is pulled.
I adjusted the lifters and the idle smoothed out. Running MUCH better now but not perfectly smooth like it should be on a stock cam.
Here's a pic of the mess under my shiny valve cover:
...and that's AFTER being cleaned! The first time I popped the cover I couldn't see the head bolts.
Here's the plugs in order.
#6 is as the top, #1 at the bottom.
I drove it into work today because I haven't driven it a single mile in a month. Ran really well until lunch time when I went to restart it. Idles rough again. Give it a blip of throttle and it's fine.
I think one of the #6 lifters might be not holding pressure. It could be either one as far as I know.
How would I tell if it's dead and how do you change lifters?
