hapiboi: My toyota camry 2000's engine runs smoothly in idle mode, but while driving with little acceleration, it decelerates and picks by it self. This prompts me to press the accelerator pedal well but the acceleration does not the usually expected speed. The car also brings out dark fumes from the exhaust. I have servised the injector nozzles, blew the air flowmeter, even changed the airflowmeter sensor with no appreciable difference. Pls any clue to what could be happening to my car. Engineers in da house helpppppp!!!!!!

ojmaroni247: Ok den,try cleaning de injector,buy 1 of dis injector cleaners nd turn into ur fuel tank nd see hw it performs

hapiboi: thanks for ur contribution. The plugs are not soaked but dark with soothy fumes. It als consumes fuel like mad.

chiebube: SECONDLY, IF UR CAR IS NOT STEADY ON SPEED. CONSIDER CHANGING YOUR FUEL PUMP. ITS JUST N4,000 MAXIMUM. I AM NOT A MECHANIC BUT I HAVE CHANGED FUEL PUMP MANY TIMES BY MYSELF.

EVEN IF IT IS NOT THE FUEL PUMP, CHECK THE INJECTOR. U MAY CONSIDER USING A CARBURETTOR CLEANER TO CLEAN IT. I AM USED TO USING THIS THAN USING FUEL ADDITIVES. BUT PLEASE HAVE UR SECOND THOUGHT ON FUEL PUMP. AM SERIOUS

This is the only person that made sense.
This is part or all of your problem. Your plugs have prosecuted you and exposed your neglect.

Take a picture of all your plugs and number of mark the wells they came out from. Take a clear picture of your hood bay as well. Hope you did not throw parts away. Nobody is on-site with your vehicle so I (and concerned NL'ers) will need all the images I can get to you to the furthest help that can be rendered. For the plugs, I'll need the part number and the brand and also the inner profile where the ceramic (white) is situated. If there is huge alphabet on the plug besides its brand name or logo, display it. The process of elimination will begin from here.

The mass air flow meter that you took out and the one you mounted should both be pictured and uploaded as well. It'll be useless not to display the part numbers. If you cross-branded the part and you aren't certain it is for your vehicle, you will have to revert to the former; there was nothing wrong with it.

If you have faulty ignition cables, we won't be able to help you online. It'll need to go to a shop.

A word of caution: under no circumstance are you suppose to use a carb cleaner or choke cleaner (whatever that is) anywhere on that vehicle and worse, when you don't understand what's going on.


So far, only three aspects can go wrong. One has been partly identified. Nairalanders from this point will be able to help you (especially those that have the very car this discussion is about).



You have to be very careful giving advise to a person that is desperate. There is nothing wrong with his fuel pump. A carburetor cleaner has no place on an injection engine.
