Dekhi kite gear na pa dami, mere truck ne chand toon pikup nai karna tuhanu,,,lol

car is running rich like crazy!! could be misfire or in my case it was upgraded injectors and the car wasn't tuned for them. you could also maybe have a sticky fuel injector.

the person who tuned my car when it was running like this told me not to drive it, said wasn't safe or good for the engine.

thanks gagan

but isnt that black smoke of unburnt fuel particles?

not sure what to do
what do u reckon?

should i take it for a service and then get everything checked?

FYI - Reving over 5000 RPM

ya it is unburnt fuel, when the air fuel ratio is off then this happens. i knew on mine it was a fuel injector cause one of the exhuast ports was shooting out fuel lol. go get it serviced.

does it even at idle have black smoke, or only when reving really high.

only when its reving high only then it does that

normally nah

injectors nu kida clean karwa sakde ?

to get them cleaned its called flow testing. they take them out and clean them completely. about $10-15 each injector. but i think ur problem is misfire cause its only at high rpm. check ur maf, the grounds might be bad, this is commonly the issue for 240's basically the same thing for RB's. also the fuel pressure regulator could cause this.

one thing that would help is to know whether all the cylinders are running rich or is it just certain ones. if u can take out the spark plugs and clean them, put them back. drive about 5 mins then check them if there black or not. whichever ones are black are the cylinders that are running rich. this will tell u if its a injector problem or something like a mass air flow sensor problem.
