similar problem as yours. I have my car tuned 2 times in Proton Edar
Service Center (PESC) Mutiara Damansara. They used the PDT2000 and did
some reprogramming to the Siemen ECU. Now, it is still the same. They
can`t do much. Now when the air-con compressor kick-in, I step on the
accelerator a little to rev up the engine. I think the vibration is
unbearable in the afternoon only. When the air is cold, in the morning
and at night, it is acceptable. I read in another forum, that faulty
steering bush can give such problem. My steering has no problem except
when I am driving up Carrefour Subang Jaya parking lot (upstairs). I can
hear knocking sound from the steering rack. I am not going to PESC even
though my car is still within the warranty period. I am sure they will
tell me there is nothing wrong with the sterring bush. I will let you
know if there is any improvement once it is done.

That is normal.

wira is a 1.5 1995 model , injection model from that year is rare becaue
mine is export wira . when the car engine life is older , the idle rpm
should get higher . this is what i heard from forummer . i adjus tit tp 950
, it cures my vibration problem , then i turn on my aircond . the rpm drops
to 750and vibrates a lot . so i tune it with aircond on , make it reach 950
, but once i turn off the aircond , the rpm goes up to 1100-1200 , i assume
this as a quite high rpm alread , so i tune it back to 950 during aircond
s , sifus here , my engine deosn't rev up to maintain the power when the
aircond kicks in ... so , should it make the idle rpm at 950 during aircond
off or aircond on . if aircond off 950 , aircond on is 750-800 . but when
aircond on at 950 , aircond off will be 1100-1200 . which one is better ?
i heard that there is something called FICD to control the revv ... so FICD
is for carb engine or injection engine ?
