Subject: [LML] Re: Fuel injector = cleaning

I just wanted to follow up on this old note of mine.=   I had an inspection done by a local shop in May 2011 and therefore d= id not think the plugs would be a high probability item.  I've had har= d starting and idle problems all summer.  When a plug stopped firing y= esterday I pulled all of them and the gaps were set to something less than 0.010 on 1= 0/12 plugs.  There were some balls of (lead?) deep into some of the pl= ugs, whitish deposits on the insides and some of the gaps were shorted of c= ourse.    These are massives, RHB32E on the IO-550N.  These = plugs had about 70 hours since the "condition inspection".  I forgot t= o check the resistance that one owner wrote about but I did test them under= pressure and all fired properly after cleaning. 

As suggested= here, I did not go after the injectors.
