i swapped a running engine from a 99 eclipse to a 97 talon&nbsp\\; and when u press on the gas slowly in nuetral the car will accelerate in rpms, but if you press any weres past half way on the gas pedal it will bog right out and stall.i have changed out every thing from sensors to fuel pumps, injectors, computer, filters , vaccum lines everything.the check engine light is not on but i felt the radiator hoses and they are hot and the car says its half way in temp.so i switched out the temp sensor and same thing appeared,the over flow is boiling sometimes also,could this be the problem. the car seems to run great when you dont press on the gas all the way, but sometimes you cant even press on it at all. the weirdes thing i ever seen, figured i would through it in this forum because i cant find any help on this anywhere.
thanks jesse

 

the only thing i can think of is could be the maf sensor or not enough fuel or spark
