Somebody help!!!!!!!!!!!!!!

I got the car from a buddy Dont know if if was running bad before all i know was the plug plug in number 4 Kept coming out crushed


So i took a motor with 153 000 km on it and swap it in.
When i go to start it i have to hold my foot to the floor it pops and fires trys to start. Then when it dose finally catch on it stumbles and bearly wants to run(foot still to the floor) THen after 20 seconds or so Its Reves out to 5grand and clears its self up and runs. Runs good starts goods. Then let it sit for a couple of hours Dose the same thing

When you Frist go to start it, it sounds like a car the distrubuter at -5 degress. Then when it dose catch on it sounds like a flooded carburated car. Any ideas

As Well theres a plug I have no clue Where it gose its driving me nuts. I traced the wires to the ecm its pin 53 and pin 52 ,,, acording to my book But m book dosnt show 52!!! Will this effected how it Runs?

The Car is a 93 ford Mustang 2.3 dis

ahahahah I must not have made it clear. Thats why i swaped the engine. But i think have may have figgured it out. The donnor car was a 92 mines a 93 i put the 92 coils on. The firing order is diffrent, ill see after work if that fixes it.

Well I feel Dum now.
That was the promblem with the car all week i played around with it. I tested every sensor to make sur eit was working right. Oh well another lesson learned.
