Hey Chris==You really need special gauges to check the exhaust gasses. Take it to a garage that haas these gauges. GoodluckJoe Thanks joe, but I just got emmisions, and everything that Arizona emissions testing tests was about 1/2 the limit, where 2 years ago they were less than a 10th. I had the injectors replaced, and changed out the Y-pipe on the exhaust before, but now the gradual problem has given my car a major performance hit, the exhaust is very rich, (in other words in engine not getting enough air). What could be things that would cause that? I use sythetic oil now to help protect, but there is definatly a problem. And lets say it's not compression, what then? Check your EGR valve. A plugged EGR will cause loss of power and will cause the exhaust to smell like rotten eggs.
exhaust will be smoky. exhaust temperature will be high.
exhaust will be smoky. exhaust temperature will be high
Upgrade the intake, exhaust, and fuel injectors.
the exhaust side is by the exhaust manifold,intake side is next to fuel injectors.
programmer, more boost, larger injectors, intake, exhaust.
Automobiles release exhaust. These exhaust gases deplete ozone.
I HAVE THIS PROBLEM ON AUDI A4 2004 PLATE, IM CONVINCED THAT IT IS CAUSED BY EXHAUST BLOWING AS IVE HAD IT SERVICED RECENTLY
Are you sure it's a leaking exhaust? If you think it is, then get a new exhaust fitted! But are you sure it isn't diesel smoke coming off the exhaust due to leaking seals on one or more injectors? That's the favorite!
Injectors, timing, low cylinder pressure.
First question is do you have a spark? That is the most likely problem. Other problems that would cause raw fuel in the exhaust are bad injectors or a bad fuel pump - although to have all the injectors go at the same time would be nearly impossible.
The purpose of a cylinder head is to safely house the exhaust. It also has the purpose of housing the intake valves and the fuel injectors.
rough idle,execsive smoke from exhaust ,low power could all be symptoms of bad injectors . also check the delivery pump pressure it could also cause the same symptoms
