Rich fumes from exhaust pipe

[Imprezho]

Does any one knows how to solve the issue engine running to rich as exhaust does get strong fume smell? Does decarbonizing the engine using the liquid helps? Btw mileage running at 104k already.

Please help.

im not sure whether dcarbo works anot. since as already reached the 100k km mark,
time for top overhaul.

strong fume from the exhaust is one of an indication of ignition not properly firing. please check the ignition system for any problem and report back, tq sir

fyi, my dad's unser hit more den 300k km, and there isnt any fume from the zorst

I think ill try to go for the decarbonizing first since it acts as a top overhaul. So far ignition is not a issue to me as i do not have any ignition issue as i change my spark plugs every 15k servicing.

sorry for tumpang your tread..

wat other factor if exhaust has some petrol smell?/

Dude its probably due to your combustion. Is your engine running to lean for petrol to derive to carbon mono?

How is your fuel consumption? Does it get worst than normal?
If your ignition is fine, I assume your AF ratio is running too rich.
Your O2 sensor in good condition?

i do face the same prob.. my foreman said my petrol is rich after being upgraded. is it normal to put a/f rch as im using highcam?/ btw, my petrol is worst.. any suggestion?/ no sensor, carb engine.. eheheee..

 

[Imprezho]

Currently my fuel consumption is alright but slightly more than usual. Currently running at 104k mileage which needs a top overhaul. Car is in standard mode. Just changed extractor and air filter only. AF ratio?

u sure its from the zorst? leakage in the fuel tank area can also exert strong fuel smell

 

[BE5RSK]

I do not understand why you need to do top overhaul, when you/your mechanic still do not know why your car exhaust emitted some fuel fumes.

If I were you, I would do the compression test, get the AF reading and checking any leaking on fuel linkage first, before straight away jump into conclusion it needed for top overhaul.
