[s-cars] Poll: Who's using a 1.8T coil conversion

[tedebearp at yahoo.com]

The output test was worthless for diagnosing my intermittent low boost condition, which turned out to be a bad WGFV.  The WGFV worked fine when actuated about once per second during the output test, but wasn't keeping up at higher duty cycles.  I wasted time replacing hoses and checking other things before I came back to the WGFV and tested it with a function generator.

The hiccup you describe doesn't sound like the more prolonged low boost problem that I had, but you can disconnect the WGFV  from the wastegate (and plug the hoses) to see what happens. If you still have the hiccup, it wasn't the WGFV.

It was in my original question, but I actually did change plugs to NGK coppers from iridiums trying to see if the lower voltage needed to produce spark in the coppers would cure the issue (still thinking it was weak coils), but it didn't. I've run the output tests and all things function as they should, including the WGFV. The only things I haven't touched is the EGR and PCV valves.  They're original. I'm wondering if there's a vacuum leak in the line to the MAP sensor or if my car is just one of those that doesn't like the updated coils of any variety and I need to go back to stock.
