Ok I have a 97 neon I did a 2.4 swap and it ran awsome for a couple months then out of no were it started running like crap only when I went past half throttle. as long as I dont floor it it hasgreat power but when i do floor it I go from being pulled back to falling foward and feels like im all of the sudden pulling a car behind me its losses alot of power and is struggling realy hard to accellerate. I have tried different throttle body sensors, pulled the engine harness to check it,changed map sensor, changed differnt computers. and when it happened I noticed the speedometer wasnt working so both them things happened at the same time. any ideas!!!! Realyt frustrating.
thanks
