recently i just bought satria 4g91 injection manual.after a month i had changed aerospeed triplecore spark cable (coz existing already missfire)+denso iradium spark plug+k&n open pod.now my car seems loss power i.e. no top speed n fuel consumption also bad (rm20 from shah alam to klang bukit raja for 2 days and drive in relax mood).there is always jerk in 3rd gear and sometime in 4th gear.sometime when i turn on aircond,the car semput2,and afetr turn off,back to normal.my fren told me may be due to throttle body but my rpm is ok (less than 1, and above 1 if aircond is on=normal rite...).fyi, my piping is a standard 1.3.wanna change to 1.8 inch but want to resolve that problem 1st.i had changed also fuel filter,airflow sensor b4 coz a pomen advised that.i bought this car for everyday working use n now this problem really made me not cool...plz advise all otai out there tq
