Maybe its time to change your plugs.

Maybe its time to change your plugs.

My last service was a major service.
changed to iridium plugs .

Maybe your clutch slip at high rpm?

Hmm, clutch plate also upgraded around June last year,may b clocked around 10k km with
the new clutch plate

feel heavy revving up?

Here are few possibility :

1) Throttle body cleaning or maybe a simple de-carbo job
2) Check and make sure the air-con gas pressure is correct. Incorrect pressure will put more strain on the compressor.
3) Try using fuel other than Shell ron95. My experience with Shell ron95 : car feel very light driven below 4k rpm. It takes forever even to get past 5k rpm.
4) Under inflated tyres can caused higher than usual fc

i think i should check the air con gas pressure as i just serviced the air cond last week .
throttle body i just serviced few months back. anyway i will get this two things checked.

feel heavy revving up?

no bro,no such feeling.no heavy feeling.no burning smell also.

Check your coils. I would safely assume that would be your problem.

err..kinda blur ready. what coils are u actually referring to?

 

[K_Takuya]

What clutch u r using?

 

[Neo_]

Mivec 1.8 bro.

btw,can this be caused if something wrong with my exhaust system?
any possibilities?

 

[K_Takuya]

yeah.. wrong setup can make u loose top end, while good at low end...or vice versa.. u cant get them both...that's why there's turbo kit in the market..

 

[ronaldindin]

you might want to check your plug cable, try to borrow from your friends?

 

[Neo_]

can you be my fren? hahaha

orite..will get it checked today and update further

 

[mouse8899]

Yup, exhaust system plays a big role on choosing your RPM bandwidth :)
