H2 Engine Misfire

RE: H2 Engine Misfire
Well as promised, here's what was discovered to be the problem with th engine misfire. (after giving up and taking it to the dealer, ouch!) On the rear of the supercharge intake there is a vacuum stem approx. 3/8" that the cap was missing. This is an extra vacuum outlet use for other applications, according to the Rep. from the makers of the supercharger. Asa result of the open (unpluged) stem, (the plug somehow had fallen off AND it was located on very rear side of the intake), it caused the engine to run very lean and misfire. After the stem was pluged the tech also discovered that 2 of theNEW plugs were causing a misfire on #2 & #5 cylinder. After changing out the NEW plugs with another set, the problem was solved. By the way, prior to taking it into the dealer we did look for vacuum leaks with brake clearner however this plug was so far back under the fire wall we never hit that area with the spray. So much for trusting new plugs. The first set of plugs were made by Bosch, called "No Gap" . They seem to be good plugs. Iguess we just got a bad batch.

Before you start fooling around with the injectors..run a couple of cans of this stuff through (1 can per tank full)...This stuff is phenomenal (pricey too, about $20.00 per can), But it works miracles..Google it to find a distributor near you.
