Engine is difficlut to start when it's cold outside and the engine is cold. But starts great when the engine is warm, no matter what temperature outside is. When it finally starts it does not increase rpm to 1100-1200 to warm up, instead, first minute rpm are about 400-500 and when slowly increases to normal idle. The coolant temperature gauge works fine, so I assume coolant temperature sensor does too. Going to change it anyway when the part arrives. Changed IAT sensor, it didn't help. I don't know if it's related or not, but when you just start your ride the gearbox startes to shift as transmission oil has the right temperature (shifts to higher gear to keep low rpm), not like it used to be before.
Also the problem started to arrise slowly, just every time I had to start the cold engine it took longer and longer.
And no engine lights or whatsoever.
So the next thing would be fuel line pressure? Can I nfortunately I dont have time now to take my car to mechanic for testing it, but I will ASAP. Just curius up front what the problem is and of course desperate to fix it.

 

Just FYI who may have similar proble. It was defective engine coolant temperature sensor.

 

Hi,Maybe you can take you car to mechanic to testing it or if you want to DIY you can have a OBD Diagnostic tools to check the problem.It is very easy...
