engine overhaul

[RENESIS VIII]

Should be running very rich..i think

If running rich, any method to tune it down? Through ECU setting?

some cars, especially those performance cars memang run super rich...

better rich than lean i always say~

But mine not super performance car. Bare basic old car.

Like bro Izso said, there might be exhaust leak somewhere or some fail seals thus bad fuel economy. Maybe you can try cleaning your tb like he said...Cause stock car and ecu won't run rich till that extend.. I'm just guessing will need sifus to confirm

The thing is after warm up no more smell, that is why I think more to cold start rich mixture.....

Remind me again what model is your 4G16 Renesis? MMC or Siemens?

Back in the day my car never had that kind of rich-petrol-fume smell. It had a bit but not to the extent it'll make you nauseous like yours. And the smell dissipated very quickly. I'm thinking the initial startup running rich is either because of your plugs, plug cables, coil or your O2 sensor. Got money change them all if you haven't already sometime earlier. These things all are wear and tear

Pullout your spark plug and check the color or gap and insulator. If the color was dark brown or black. Your air fuel mixture was rich adjustment... If it have oil and carbon deposits. You need to TOH your engine.

MMC. The smell in my car seems to go on for quite some time until the engine has been warmed up. For example, if I have went out for a drive and come back to my house, there is no noticeable smell from the exhaust even when I am kneeling down next to the exhaust. Only when during cold startup, the smell seems to be everywhere.

Seems quite bad because when I pump full tank, I only got around 280km mileage or so and it is nearing the end of the fuel gauge. Below the last bar but fuel light haven't start blinking yet. I heard some people can achieve 300km with auto...

One day trip to pj

Going to PJ on tomorrow. Following family, without my car.

Hmm...my old 4g91 (1.5) with kinda bad valve body can do 300km driven heavy footed lol...yours is manual right? can start with basics like clogged cat con, plugs, clean tb etc.. just my 2cents

I guess my FC really sucks then. If on city driving, FC is even worse. Throttle body seems ok the last time I checked it. Will change the plugs soon since that is the cheapest.

Sounds like your car needs some tuning.

Mechanically or ECU?

I keep blasting carbon away whenever I drive. Occasionally I rev to 4k rpm and above.
