Hey guys. Help me up abit here aite.
Recently my satria 1.3 SVDO has been very sluggish in terms of acceleration and pick up wise. In other words, it feels laggy and no instant throttle response.
I am listing down the list of modifications I have done to the car. BTW it got worse after the exhaust and LCP.
1)Performance drop in
2) 4-2-1 extractor from W.Heng.
3)1.7 inch outer diameter piping following original route, one mid bullet and a big tabung straight flow exhaust OEM style.
4) Engine oil 15w50 from Mobil, change every 5000k. Sparkies are normal OEM, plug cable OEM, I think are in good shape.
5) Undampened lightened crank pulley. (this is where I feel that it is sluggish the most). No instant throttle response.
I installed a vacuum meter, and I realize, that when I am idling, and when the AC compressor kicks in, the vacuum needle does not stay still, instead it kinda jumps back and forth. I can feel the engine slightly revving, like it is on high cams. So lets say if the AC kicks in, and the needle shows a reading of 15, then it will hover between 14 and 16 slightly and the engine revs a little, like I said, being on high cams.
I am not sure of what makes my car really sluggish also, unless someone can recommend me a good mechanic around Port Dickson, or Sunway and Subang area to diagnose my problem.
Thanks.
