Lack during driving for Airtrek Turbo 2.0L

[jackng78]

I got Mitsubishi Airtrek turbo 2.0L last year and newbie here... recently i feel my car driving is not smooth... it is lack during driving, look like the fuel loading not smooth. I went to Mitsubishi car center and the guy told me maybe the fuel pump or gearbox got problem. anyone got this problem before?? Car's manufact is 2004.

Bro, u need to be more specific what is the issue you're facing. When you're saying 'lack of', does it mean power? What else is not smooth? Maybe these questions will help us understand more.

- Lack of power?
- Does it vibrates when turbo kicks in?
- Is there any weird noise when turbo spins?
- Is there any weird noise during gear change?
- Does your car choke or missfire at high rpm?
- What was the last thing you did lately before the synthoms appear?

Lag lah bukan lack, adoyai

Could be dirty fuel filter. Try removing the fuel filter and see whether it is dirty first.

have u checked air flow sensor ? faulty air flow sensor cause this kind problem also ....

 

[stutzedward]

check yr vacuum pipes. did the boost level dropped? will it vibrates when turbo kicks in?

to answer your question as below:

- Lack of power? Yes
- Does it vibrates when turbo kicks in? Nope, but it look like fuel come not smooth...
- Is there any weird noise when turbo spins? nope reayll hear that..
- Is there any weird noise during gear change? nope.
- Does your car choke or missfire at high rpm? never try it...
- What was the last thing you did lately before the synthoms appear? I remember that when I used 97 petrol this synthoms gone away, but recently is come back after I used petrol 95. It is related??

Nyantong,
Do you know how to open up and check it?

 

[stutzedward]

If 97 is ok n 95 is bad, then it's knocking. U need to stick to 97 bro.

 

[kaninbu]

bro,mayb ur trek need some fine tuning only.ron95 n ron97 sure big diff interm of power.even price oso diff so much.

 

[jackng78]

let try ron 97 for while... thanks bro your advise....

 

[stutzedward]

By this way, is this happening only or more apparent during hot afternoons?

 

[jackng78]

I experience only on morning and afternoon, but seldom driving at night. it is happened when I try to press petrol that time...

 

[stutzedward]

Morning but air temp is warm right? So let's say u got stuck at traffic jam and when u accelerate, the car felt heavy and doesn't wanna go. I am pretty sure it's knocking. We all hv this issue with original intercooler. It's BBQ'ing the intercooler during jam.
