Does anyone who got their cat-con removed notice the exhaust fumes smelled like unburnt petrol when using ESSO fuel?

Asking on behalf of friend. His car when full turn steering (or U turn) then drive for a while n stop, the RPM goes to 5k and it won't come down until turn off engine. What happen?

He go several EON or Proton Edar they tell him is like that!

Maybe AFR or piping got small leakage? Just guessing here.

Correct. Got small leakage at the dummy plug but only occurs during cold weather.

Is it because GAB sport spring too soft or too low and not compliment with stock absorber? But i planning to go full adjustable suspension too but not too soon la coz no money..huhuhu
To bro markiliz

huhu..not staying there. My wife home town la..huhu.. Sometime only "balik kampung". But ipoh/tambun i often go.

hope to get some advise on the engine thing, I am abit annoyed by the engine jerking feeling of my m/t gen2 cps. I did 2 test on my car:
1) Engaged to gear 2 after road bump, left foot off the clutch and right foot also off the pedal, let the car cruise at slow speed at approximately 20-30km/h, can feel the 3-4 times continuously jerking , and followed by smooth cruising for about 10 second and before jerk 3-4 times again... and on and on and on like this.

2) Free the gear, press pedal and maintain rpm at 2k, can see the rpm meter moving up and down at 1.6k-2.1k speed range, esspecially when the a/c compressor kicks in, RPM fell until below 1k and up again to 2k....feel very frustrated driving slow now.

Is these normal situation? I am thinking to go COE to complain if this is not normal.

Try to get some pics bro!
