    Probably Compression leakage

    i dont think its a compression issue. you should check if the MAP sensor is working properly. if you engine has a MAP (manifold absolute pressure) sensor then you should check its wirring, or if your engine has a MAF ( mass air flow sensor) then check its working. basicaly these engine take MAP or MAF sensor reading and calculate the amount and pressure of air coming in the engine, they then adjust the fuel, injectors and ignition accordingly to make the best AIR/FUEL ratio. right now in your case i think the ECU is not able to know how much air is coming in the enigne so its just dumping all the fuel it can tot he cylinders, hence less air and more fuel and you have KACHRA/ kala dhuan/ unburnt fuel in result.

    so in short, check your AIR sensors/ or oxygen sensor..

    The Blacktop beams is very notorious when I comes to the combustion when the MAF isn't properly set, I've been through it.

    yeah i know.. not only the Beams. but any toyota engine i think. right now i am fighting with my 1jzgte vvti engine with a MAF sensor. after so many days of effort came to know the sensor is bad. so got a new sensor imported from Ebay.

    it will make a lot of difference.. right now if you dont have oxygen sensor that means the engine is not geting any data of what is coming out of the exhaust. how can it adjust the air or fuel ratio. you have to put the Oxygen sensor to properly let the ECU set the Ratio. i mean its really important.

    as far as the mechanics are concerned in lahore, their are few but the problem is time. mostly people here doing such work have more projects on their hands than they can handle. which eventually delays every one and you just keep going and coming to the workshop.

    aap workshop k chaker he lagatay rehtay ho, aur kaam bohat he slow hota hey. isliye i prefer doing it my self. but if you still want to know then i would say k check REDLINE guy, go to him or talk to him on phone, he is well into 3sge or 3sgte. he knows these engines pretty well top to bottom. but before you hand over the car to him. decide everything prior to initiation.

    1. total scope of work.
    2. time of project.
    3. cost of project.

    time being the main thing.
