: do you set it to factory specs?
: less than or greater than factory spec?
: how is the idling?
: my 89 at factory spec: .25mm (.010) it idles rough and misfires, will increasing it to .011 or .012 smooth down the idle amd misfires abit?
I set mine to .010 too a few weeks back and thought that I must have had it wrong (set them a little off possibly) and so I did it an additional 3 times and my brother attempted it once too. All times we got basically same result as you. misfire and really rough. I don't get it either. Some have said setting it to .012 will even the idle out a bit, but I couldn't care about the missing or the rough idle (especially). really all I want my car to do is idle normally and fall back to idle in a reasonable amount of time while my AC is turned on. I've timed it with my watch and when the AC is off, it'll take about a second or more to fall from around 2-3000 rpm (from the moment I take my foot off the gas) and when the AC is on for any length of time, the idle takes well over 5 seconds from the same point!! I'm so frustrated over it I'm thinking of selling the AC system out of my car (And I'm in central Texas, where it's 98% humidity while bright and sunny at 95+ degrees.) If anyone has a fix for either of those two problems, please post them!
TIA,
Thomas Goodwin
PS: moral of reply -> Don't do what I do. I thought I had it wrong when I actually got it "right". Don't waste your time doing the valve clearance over and over again like me.
