[chenfon]

Thanks guys. this weekend will try to replace the said cable with new. hope every thing go smooth. thanks.

another issue come out after she come alive, during idle the engine seem minor shake and sound like 1 sparkplug not work. but all OK when i check 1 by 1 plug by direct pull out during idle. Possible TBody dirty? or the "Idle thermostat" below TBody dirty? due during cold start, the RPM beautiful at 850rpm (with minor shake) but after drive few minute and stop at idle, the RPM will at 1100rpm with non stop up and down (100rpm). wonder what will cause this other then TB? please do advise. tq

on the engine overheat during high speed, i had tighten all the coolent hose with hose clip. After test for few days, it still have minor high temp (high speed) where gauge display 2/3. still work on it. tq
