Engine Trembling

i've been experiencing a problem with my car since i bought it (second hand) ....it's a EG8 1.5 Single Cam fuel injected automatic Vtec....during driving (cruising speeds) the engine trembles & the car acts like it's straining to move.....i'm loosing acceleration power ....i have to mash the gas peddle more to speed up so the engine will stop trembling....i thought it was the Tranny so i tried a next one but same problem....then after i changed Head & Block ....but still faced with the same problem....can anyone tell me what can i do to solve this HUGE problem i'm having it's driving me crazy & costing me alot..!!!...(i've also tried Alignment & wheel balancing that's NOT causing the trembling)......well it boils down to a few things 2 check now....Fuel Pressure Regulator.........& Injectors.....What NEX..??? HELP..!!!

 

start with a fuel filter. A dirty filter causes so many problems like loss of power. Broken motor mounts cause hard shifting. I dont know what else it would be

hmm, i think i may need a new fuel filter soon.

 

I was thinking about it and what condition are your CVs in? That could cause some high speed shaking if theyre going bad too. Just a though

 

first off are you an auto trans?
