Hi all...

Newbies here. need some input from all sifus here..
i got one p30 manual chipped from my friend. He said, after he use for several month, this problem suddenly happen. also happen if plug into my car.. the idle rattling from 1.2k to 1.5k and keep up and down. no error code given, check with shorted D4 to ground. remove J1 also make nothing different..

Opened up the case, no burning, leaking component found.change c27, Try to re-solder from half side to socket in case if dry joint problem. But still not settle up..

hope if any sifus here can make some suggestion, input..


Tq..
