??'s for guys running TR6's
 

After I installed the Heads and cam on my car, the idle got just slightly rougher.. not bad enough to set a misfire code. I was running TR55's then. I swapped my original patriot 5.3's for some updated ones about a month ago, when I did the swap I changed over to some TR6's gapped at .050.. ever since then I get that nagging SES light about once a week because of misfires and my idle is alot rougher. Am I running too big a gap on the TR6's? Is the plug just too cold? Or is it something else?
Thanks!

It's a pcm thing. Find someone that has a tech II and get them to do a idle learn or some people call it crank learn procedure. Basiccally It lets the pcm know what's normal as for crankshaft speed flucuations. I think that will fix your problem

You don't think I'm running to big of a gap on the TR6's at .050? I never had this problem with the TR55's. I can watch the misfires with my AutoTap and it is pretty much in all the cylinders, but only at idle or every once in a while when it is very low RPMs in 6th gear.

My TR-6's are gapped at like .038 I think .050 is too wide.

TR6s always seem to idle very slightly rougher than TR55s. I noticed the same thing when I put nitrous on my car and my roommates and swapped in the TR6s.

I agree, you might want to reduce the gap a little.

Ive run TR5s TR55s and am currently running TR6s.
I would say your gapped to wide, you might try to reduce it to .04, and if you are spraying on a gap that big, that is your problem.

Yeah, I'm thinking my problem is the gap. I am only spraying a 50 wet shot, but the other night when I sprayed it at the track it started misfiring at WOT. It never did that before I changed the plugs. I'm going to take them from .050 back down to around .040 tonight and see if that helps.

Re: ??'s for guys running TR6's
 

they're .035 out of the box if i remember correctly. for anything 100+ shot i wouldnt gap them any more than .035-.040 just FYI.

Re: ??'s for guys running TR6's
 

Cool.. I'll do them at .040, I'll never run over the 50 shot, hell I went so far as to throw the 100 and 150 jets in the garbage so I wouldn't be tempted to use them on the stock fuel pump with my heads and cam.
