I've got a problem wich i can not figure out to save my life... :S
So the problem.
I've got Honda accord CC7 2.3i SR wich has f20a4(i bought it that way) from a 4th gen prelude it it.
as far as i can tell everything on the engine is swapped except ECU(p44-g20) and all its wire harness. From ecu to engine.
And the problem i am having is that it wont start properly when the engine is cold but will start from half a turn when it has been runing for atleast a minute(yea exactly, 1 minute atleast).
And the weird thing is that if i crank continuously it wont start, but if i crank for 1 sec, then stop, then on second try it sometimes starts but sputters at start a bit at ~500rpm +/- 100 and then revs up but sometimes it stalls after sputtering then 3rd try it starts.
AND when it just has started if i press throttle sharply it seems like it's about to stall an then revs up...
and i repeat... All this happens only at 1st 1-2 mins when engine is stone cold...
Here some videos i took
aplying sharp throttle after just started cold-
Thank you in advance for any advices...
