Poor acceleration, system seems to lean out off idle. Fuel volume and pressures are normal. Replaced almost every fuel related component once if not twice. Engine runs normal during warm up but once lambda control starts it accelerates poorly. Unplugging the EHA makes no difference. If I plug in a cold coolant temp sensor on a warm engine the idle speed increases slightly and engine acells normally. Don't know why there's no fuel enrichment on acceleration. Any thoughts would be appreciated
