In some serious trouble, it broke...

Those Z1 mounts are rebuildable. A call to Jon to ask what the symptoms would be if one let go might be an idea too.

Joepro · 04-01-2014, 12:54 PM

Im about out of ideas, im posting a video but again its hard too see the issue in the video... mountsare tight a pryed on everything over and over again.

jwick · 04-01-2014, 01:05 PM

Any metal on the drain plug?

The high idle sound like an air leak. Check your vacuum lines and possibly replace the 5 manifold gaskets. Checking the mafs and the couplers behind them wouldnt hurt

If the internal poly structure of the mount came apart, would they still be bolted in tight? Looking at the cutaway on the Z1 site, if the poly failed you'd have a crappy metal mount that would vibrate all to hell. Also, are the welds on the new header flanges in good shape?

One of my techs a work looked at it briefly and does nto believe it is air/fuel related, he describes itas something off balance, the pulley looks fine, the flywheel looks fine through the check plate. Life hating engaged.

gonna drain the oil now.

If you don't find anything in the oil I would take a look at your manifold again. check the hose connections, and the pcv valves, anywhere extra air could be getting in. Did you check the codes with a generic scan tool or with consult3? there are a whole bunch of codes that GST's cant read, might be worth having it checked with consult

Can't you spray some sort of carb cleaner to see if it affects idle?

I got a idea while thinking about it. What is the chances you put 1 of the 2 MAFs in backwords? This would cause a whole whack of unmetered air to enter the engine resulting is a pretty big mess I would assume.

Worth a look.

Chuck33079 · 04-01-2014, 02:49 PM

Ok, stupid question- how many miles since you installed the kit?

That would be a logical question to ask, lol.

I know, right? And we all missed it. If it was 1 mile, probably an install issue. If it was 1k miles, probably not an install issue.

If I recall properly he did some data logging so not 1 mile but the kit hasn't been on long so most likely not a thousand.

Joepro · 04-01-2014, 03:17 PM

989 miles, had some other tech come over from acura, they agree the motor sounds fine,they said it acts like a broken chain on a balancer shaft but Ididnt think our motors have one?they all agree its roational not air/fuel, one think I should drop the trans and look at the flywheel. I also looked atthe log when it happed, the a/f boost were all normal.
