What i already did

 

I went back to ming ghee to verify if the mount is original and according to them it is

 

Went to autobacs brought this $25 a small packet of engine revitilizer pour in EO still the same

 

Cleaned throttle body with the WS that change my mount. (no more confidence in him anymore)

 

Paid $120 to wash aircon and top up ho liao (i dunno what) with the same WS.

 

Got the same WS to check the engine mount screw which he claim is ok

 

Going to check soon when i have the time

- Rotor and rim wrap

- Brakes

- Unichip retune

- check intake manifold?

 

Anyone have a reputable WS for lancers? PM me if possible. i suspect that the screw that hold the engine mount is the problem, because for 2 fine days everything is ok. after that then vibration become stronger.

Intake manifold refers to your air filter. Since you said change to stock, the only thing is fuel filter and fuel line, spark plugs and unichip. The safest bet is change back your unichip first since it is not stock. Follow by spark plug as it is cheaper then fuel filter which also requires huge amount of work.

yup air filter stock at the moment. will try change spark plug and retune then :)

My WS did something with his OBD2 computer and now vibration lesson to around 30%. previously idling very unstable, now more stable. Previous idling at 500-600 rpm, now around 600 - 800. Still have vibration was told that a higher rpm at least 1k is better. Not sure how to do so.

might be maf sensor dirty thus causing rough idling?

I feel this is the reason.. Plus dirty throttle body.

Bro try to on yr head light and see the RPM increase to 800?

My 2007 toyota wish have the same problem when the RPM drop to 600 and vibration.

when I on the head light the RPM go back to 800 and vibration gone

2yr ago I bought 4 pcs mounting from s'pore($265)and replace in Malasia($60RM)

after replacing the mounting vibration was gone, now it coming back.

Already cleaned MAP sensor and throttle body.

 

My car is auto headlight so no difference in RPM :)

its the engine still performing as good as before? or its purely vibration? its it only happening when the vehicle is cruising?

all is still well performing, engine powerful with pull also. purely vibration when stationary. No vibration when cruising.
