My car is a 7g ss a/t
i notice that pag paakyat........hirap na hirap sha. umaabot na ng 2000 rpm ko hirap pa rin. also, going to third gear, i have to release the gas pedal para mag-shift sha or else aabutin around 3k rpm bago sha mag shift.


just had the htw and plugs changed to brand new oem.
so as with tune up, change atf and engine oil a couple of weeks ago.

please advise.
