i have replaced the engine with a 302 out of a Lincoln that’s all I know about the car it came out of. Swapped all stuff from engine to the other. NOW,@#$%^&^&$. when it warms up, and when you come to a stop or it is idling (after being warm) it changes from a regular idle to a rough running all most wants to die (but does not) shakes, needles on the dashboard wig out, If I step on the gas and rev it a little it quits for a while, but dose it again a few minute Later and on and on. Also, when driving it has a little trouble shifting from 2nd to drive. @$%#%^$%^%&, I HAVE REPLACED: Spark plugs Spark plug wires Airs throttle control motor??? Timing chain Cleaned the injectors New map sensor O2 sensor Smoke test for vacuum for leaks (one found) fixed, no change. Spayed carb cleaner all over to see if I could find any other leaks, (none found) I Did the do it your self-test with a 4” wire to get the on board computer to kick out the problem codes by counting the number of blinks from the check engine light, i got a 114, 116 told me nothing! Full tank of high octane gas just for kicks nothing. The Ford dealership in my home town said they didn’t have the diagnostics computer/equipment to go far/deep enough into the engine to diagnose the problem, and referred me to another bigger ford store. They also, forgot to put the EGR line back on, causing the check engine light to come on freak me out. They said wasn’t anything they did, and sent me down the road. 5**** F-I-V-E**** mechanics have looked at this van. Yet the dam van is still STILLLLL! not running right!!!! I do not know what to do. Similar problem have been discuss on line and in forums but no one will say what they did to fix the problem. It’s just the problem, or they want money for an answer that may or may not work, $48 flippen dollars for a maybe is too much after all I have spent. Though I’m still ahead $150, for the van $350, for engine and about, and $600ish for the list above. Though I’m coming to my limit. Has anyone experience this problem or silemer problem, what about the on board computer, should I replace It I can get an aftermarket for about $200. Where do I go from here? Thank you for reading.

Did you change over all components from the van back to the 302 you sourced? The reason I asked - not all sensors and components are applicable from a Lincoln car to a Ford van and the powertrain management. So you can understand - basically what is happening is that when your engine gets to operating temperature ("closed loop") it starts running poorly. This is because your engine processor (PCM) is counting on good and accurate data from all the sensors and components - most notably fuel trim items like oxygen sensors and MAP sensor, etc. If all management components are not converted from the old to the new engine - you will have troubles. Also - why the reason for the replacement engine? Is there a lasting failure, perhaps, from the old engine? For example, if your heated oxygen sensors got fouled and damaged from oil going through running through the exhaust, it would cause the problems you are experiencing. Good luck!
