your car is spluttering so you swapped out the engine?? I've heard of Throwing parts at a car hoping it fixes a problem but never a whole engine!!
Sounds like you should have got someone to run a diagnostic first. Honestly god knows ut sounds like a fueling issue, perhaps mass airflow sensor or even ecu problem.

You clearly didnt read my post did you. I already said I done all the fuel and ignition then changed the engine
I didnt buy it, it was a spare i had. I ran diagnostics nothing showed up which is why i changed it. If you have nothin usefull to say dont reply to the post thank you

Replace the engine.

3 probs to check for, make sure you dont have any vacuum leeks or blocked air filter, check ignition system and make sure to change the plugs again you might have a faulty 1, then check you ht leads, then check the coil packs, you said you changed the fuel system you should check and make sure you dont have a leek a blocked line or filter i would also do a check on the fuel pump and make sure its not faulty, process of elimination so start with the cheapest and mos common and go from there new parts can also be faulty

i actually did, the mass airflow sensor isnt considered part of the ignition system. So what diagnostic system did you use? does it have the ability for live data? seeing air flow rate, ignition timing and fuel mix ratio would be of benifit.
Sorry if i offended you, i was only trying to use my many years experience to aid you in something you clearly have no idea about. point taken though I'll go back to fixing other porples cars and you can fit another engine...
