Yeah, I initially suspected the warm up tables/enrichment that the ECU has. That sounds EXACTLY like what mind sounds like right now--but I have megasquirt and need some fine tuning on my priming pulse and afterstart enrichments. Buuuut, mine doesn't die after it runs. Once it starts, it runs perfectly, cold or not. So, my warmup enrichments are dialed in. I guess I'd be surprised it both the old AND new ECU's had problems with their warmup tables and such. Question: You replaced the coolant temp sensor. Did you replace the right one? There's one for the gauge and one for the ECU. Brian
