    Default Problem with my Lancer A/T 2004

    Hello Pakwheelers,

    I am facing some issues with my Mitsubishi Lancer A/T 2004 for quiet sometime now and am hoping if someone can guide me towards resolution as i v already got done pretty much everything that these mechianics normally do and wasted quiet a fortune.

    Firstly i feel my car is underpowered even in petrol (but i remember it wasn't like this earlier,it really used to fly in petrol).Now it wont pick up till the speed reaches 30+ (no matter how much i push on accelerator ) and same is the behavior in CNG,its literally dead and once reaches 30 suddenly starts picking up normally..Also it continues to vibrate and shake when in the Neutral mode.

    Secondly,its keeps back firing with a sound of pathakha which in return damages the air filter (cause holes in it)....i got it checked at a workshop,the mechanics work on the ail filter box,it runs fine for 4-5 days but a week later the same back firing starts again......i don't understand what is wrong with it and neither do these mechanics appear to as all they do is the typical stuff and nothing productive....so please if any lancer owner came across such an issue please let me know as this has left me too frustrated now as i v tried everything....i would really appreciate if someone can give me a reliable lancer mechanic who can fix its cng issues along this under powered problem, I'd be obliged....also can someone guide me were can i get its engine scanned (for any current,coils,throttle body or spark plugs current issues?)
    waiting for some feedback.

    I can recall the same patakha thing and getting dead at low speed in baleno once, the issue was with air-filter box, it was messing with the air mixture. change of the box fixed the problem. u can check if the air filter box is exactly fitted in required space and not cracked from any where. (may be it helps).

    1. is the Auto or manual = "its auto"
    2. Any Chk Eng Lights = "no check engine light"
    3. is it original cng = "not sure as i am the second owner,but its landi renzo kit"
    4 try to remember any changes dones on the engine = not really,except for tappets once
    5 when was the last tuning done = not too long ago
    6. is it not picking speed on CNG or GAsoline = the behaviour is same but obv its pick is better on petrol but the underpowered feeling is there in both

    well i think it has got to be something with the fuel pressure..

    the fuel come towards the air-filter side n cause a patakha.
    So we may check fuel pressure or flow..
    anything that can disturb the suction of engine..
    check if air passage is not blocked
    throttle body cleaning..

    i know a mechanic named Waqar at peshawar road Rawalpindi.
    he deals with honda usually, no computer stuff but he can certainly solve this.
    plus he is expensive too.

    0333-5273331 (Waqar)
    the shop is between pir-wadhayi turn n chourr chowk (near Citi Bakers)

    Thanks for our feedback,i'l check this guy too but actually i v been too so many mechanics before this and i was wondering if I can find a reliable mechanic who can run an electronic scan on on my car to check it for any current leakage or a related problem...any help in this regard will be really appreciated.
