Guys car is running a bit rich (exhaust pipes are sooty and black). Power delivery & boost all seem ok. I know that I need to adjust the TPS as it is very slightly out.

 

Any suggestion were to start looking, adjust mixture etc. I will have Conzult soon to check out codes etc.

 

thanks in advance, H.

 

Just a thought the car hasn't been on many long runs recently, only 8-15 miles for the last month or so, could that have any illl effect?

 

ps. Cars running JWT chip, 14 psi, Biltz filter, standard tubs at the moment.

increased fuel pressure? fpr? kinked return line?

Fitted braided fuel lines couple of months ago to do away with standard setup. I will check those to start with and all fuel connections for kinks.

 

Keepem coming please.

Advanced timing possibly caused by incorrect TPS setting.

faulty 02 sensor(s)

TBH mate most zeds tailpipes are black and sotty, my bumper is sooty, mine idles at about 15-16afr and it still cokes up lol start worrying when you see lots of blacky grey smoke from the rear.

Thanks, I know the TPS is out, will adjust that as well. Had a new O2 sensor last year, so will look at the other one.

 

JimmyTT, yes you're right there start worrying if plumes of some appear when giving it some beans!

Boost leak would cause running rich too

faulty temp sensor ? thinking the engine is too hot and overfueling to cool
