trying to work out the hard start, cold is the worst, after it warms up, the engine will start right off. When it starts or barely starts, it runs at sounds like 300 rpm, barely running, turn on key three times, etc. step on on it a little - all the warning lights go off, etc. The car runs great. Replaced the fuel filter and fuel pump, no change, re-built vanos - no change, new spark plugs - no change. compression test - they are all 180psi or better. Replaced crankcase sensor and camshaft intake sensor, no change. I've got no engine codes at all. 188k miles. Whats next? I have not messed with injectors yet, the coils are new from 2014, all look great. Direction? Next steps?
