#105827, "STUTTERING & BUCKING AT 4000RPM"


          

yes hello. i did search for this and i didnt find anyone that has this problem. ive got a 95 eclipse gs 420a im not sure what year the engine is because it was swapped. when i put the engine in and got it running it would buck really bad and the rpm would go all over the place around 3800-4000 rpm in every gear and also around 7000rpm. i took it to the shop because i figured out it had a blown head gasket and i was hoping that was the reason it was bucking like that but i got it back today and it is still doing it, its just not overheating anymore. they replaced the gasket and machined the head and all that good stuff and before i took it to the shop i replaced the ignition wires, coil pack, spark plugs, tps and probably some other stuff idk its been a few months. so now im completly stumped the only other thing i can think it could be is the ecu because 1 its remanufactured and 2 it could be for the wrong engine because i heard the 95 year has different cams or something. the guy at the shop said its something electrical. also how bad is it to drive it like this? i stay below 3500rpm all the time. any help would be GREATLY appreciated. thanks!
