Subject: Re: State of the C4 by screamin_conure on 2015/5/21 22:07:28 Been a while since I've posted, but this thread got me going. ;) Excellent, excellent thread. I've had my '92 for going on six years now and like everyone else here, I've had my share of ups and downs with parts availability and quality. I have firsthand experience with the '92/'93 ECM issue. When I bought my car, the IAC circuit in my original ECM was flaky, causing wild swings in idle speed. I got lucky back in 2012 and found a working replacement ECM on eBay. That corrected the issue. In August of that year, I then sent my original ECM to Blue Streak Electronics to be rebuilt. I actually did that through Rock Auto. I've been running the rebuilt original now for over two driving seasons and haven't had any issues, and I still have the eBay unit as a spare. Not sure if Rock still offers rebuilds through Blue Streak anymore, but if you REALLY need a '92 / '93 ECM rebuilt, it might be worht giving them a call. I have an O'Reilly, Advanced Auto and AutoZone all just a few blocks from home, and you can throw a baseball from each one's parking lot and have it land in either of the other two. Needless to say, they get the bulk of my replacement parts business. Not especially crazy about any of them, but for certain things they're okay. I've had good luck with BWD and Standard Motor Products replacement parts and try to stick with those when AC/Delco isn't an option. Case in point...I just replaced the PCV grommet on my car with a generic fit replacement from one of the big box stores. It works, but I'm not at all happy with the fit. I also replaced the grommet in the valve cover for the breather hose. THAT part came from Eckler's because it's just not available anywhere else. The Eckler's part is an EXACT match of the original and I also discovered that the original PCV valve grommet is the exact same part as the valve cover grommet, so I have another one on order to replace the puny generic part. Live and learn. Like Andy, I'm a little bit concerned about the future of the C4 too. It was a transitional car in Corvette's lineage, and GM was trying a LOT of different ideas with it. Ideas that have long since been surpassed or left behind (i.e., Optispark, etc.). For example you'll always be able to find a quality replacement distributor for a C2 or C3, but let's see where good replacement Optisparks are in another 8 or 10 years. And yeah, this is the best place on the web for C4 know-how. Ron |
