hey guys, proud owner of 89 crx dx here, have a question. the car is running well but right around 3000 to 3400 rpm i am noticing hesitation in the motor, not harsh but enough to make it seem like something is going wrong and getting worse. its almost like a pulsation of the throttle. now i had changed the fuel filter but that was about 10,000 miles ago and i run only 91 octane. also my compression was 90,128,123,135 out of the 1,2,3,4 cylinders. i know the rings are going but could this cause my problem and if so why is my combustion so poor at this area of rpm range. it does it at full throttle and at regualr cruising speed. lemme know watchu think, i am building a 1.6 y7 block and will be putting a y8 vtec head on but that wont be completed for about 6 onths, do i have that long, again lemme know, for now shifting at 2500
