cam chain done - still hesitates when started...

Got my mate to do a cam chain kit and its a completely different vehicle. He reckoned the tensioner was around 15mm?

Still though, when starting up in morning or when coming home from work it still hesitates the first few times pulling away until it's been run a bit.


Ideas?
things to consider?
What to look for?

etc?


thanks.
 
Could be a faulty MAF sensor.See what happens with it disconnected starting it first up in the morning etc.You can also check it functioning as it should be via live data to see if the airflow reading is increasing with more throttle applied.If the engine is hesitant to rev cleanly out gear or the idle is unsteady/cycling up and down that could also be a sign that the MAF sensor is faulty.
