Hi Joe, The original thread was for stalling and rough idle for the first couple of minutes then the engine runs fine. When first started it dies immediately, restart and die again. This happens for several tries until the engine will just stay running, (very rough) . Any application of the gas pedal kills the engine during this time. After two or three minutes, no problem, engines runs smooth and accelerates fine. The replies to the thread implied the problem was in the fuel enrichment circuit, mainly the warmup regulator (102353) and the frequency valve (102395). Rather than blindly replacing these components I would rather have a means of diagnostics. Snapon Tools has a nice little fuel injection test kit for only $795.00, but I could replace a lot of parts for that much. So that's the story, any ideas.

What kind of fuel enrichment problems are you having. ------------------------------------------------------------------------ eGroups.com home: http://www.egroups.com/group/dmcnews http://www.egroups.com - Simplifying group communications
