Hilux 1990 3Y Popping Noise


Recommended Posts

Posted

Truck was running sweet and then i changed the spark plugs with brand new ones of the same brand and same code. I also set the gap between the top of the spark plugs and the elecrode to 0.8mm.

Now when i start the truck up, there is a popping sound coming from the engine and its isnt idleing well. There is also a rich petrol smell when the truck is turned on.

Any help on diagnosing the problem?

Thanks

take then off and dry out + try again
