All 4 Injectors Cleaned and Seals Replaced Outlander 2.2 4N14 Engine
 

Hi, so all 4 Injectors have been cleaned, seats cut with new seals in places. Car drives normal and no longer leaks fuel and smoke has now stopped coming from my injectors which was the end result I was hoping for. However upon starting the engine there is hesitation with some shakiness when engine turns over and starts, starts routh every time car is fired up. I'm now having to hold the key in ignition mode for much longer than normal to start the engine otherwise it just dies with normal turning of the key.

Any ideas?

Might be something going on with the exhaust pipe. Mines doing the same right now and its from a hole or crack in the y pipe of the front flex pipe exhaust.

You need MUT-3 tool and perform "small quantity injection calibration" procedure. I used to do it every 2nd year on my 4N14, but newly cleaned injectors need that too I guess.
