haha! the car got some lag/hesitation when accelerating. example, when accelerate from complete stop on power mode, 1st gear going to 2nd gear pulls until 5k and shift, 2nd gear to 3rd gear, rpm when up smooth until say 3.5k-4k rpm then it lags and drops to 3k and slowly climb to 5k and shift to 3rd gear. same from 3rd gear to 4th gear and once shift to 4th gear, suddenly the car shift to final gear and rpm drops to cruising level 3k+-. with aircon on, engine got a lot of pinging at 3.5k-4k. if set distributor and timing to stock, no power at all. so, had to advance the timing and distributor.
i don't know if it's the gearbox that's causing it but gearbox already overhauled. been pulling hair trying to figure out the problem. what i've done so far: gearbox overhauled, air filter changed works/simota to drop in, ISC changed and readjust TPS thrice, new iridium plugs, change pcv valve. the lag is not as serious as before after readjust the ISC and TPS and fuel consumption improved a lot but the car does feels a bit heavy tho.
latest problem after my negeri sembilan interstate driving, gearbox 1st gear slips/free if i shift to d quickly and step on the gas. maybe overheat coz it was damn hot that day and we did drove on hill and slope and i had to off my OD on downhill coz 1.5 disc not having enough grips.
