mazda protege Engine/ECU help!?

Question

i bought a mazda protege for 100$ a month back. It is not running due to the battery therefor i bought a new battery and i found it has a hard time starting. It takes a while to gt it started,,and then when i do, if i dont keep my foot on the gas it stalls. I later found that the engine blew nd the old owners replaced it with a new one. My car is a 1997 and the engine that they had put in is from a 1998 protege. Could the ecu not be calibrated to the matching engine therefor not sending out proper information (ext fule/air mix ratio ect.) also wen i checked the plugs today i noticed their is oil on all of them..like drenched in oil and i was wondering they problem of this aswell.

Thanks alot

i am going to give it a complete oil change tommorow but the oil lvl is perfect. im going to try and flush the gas system as well..maybe the cas gauge is wrong..hmmm

Answer 1

Is the engine oil overfull?
Does it smell like gas? The engine oil that is....

Does it have real old gas in the tank? Old gas does not burn well.

Answer 2

Get rid of it
