white smoke is a indication that water is entering the combustion chamber
might be a head gasket check oil for water and or your radiator is low on water
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.
IF and ONLY if you add a turbo or supercharger, you'll end up better aspiration (air intake) and at that point you may need larger injectors, but just changing the injector size will cause problems for the onboard computer as it tries to balance exhaust emissions.
take it to a muffler shop
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!
Automobiles release exhaust. These exhaust gases deplete ozone.
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.
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.
No that is not necessary
Injectors, timing, low cylinder pressure.
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
The sensor in the exhaust manifold is the oxygen sensor. It measures the amount of oxygen left in the exhaust after combustion. The computer then takes that information and "decides" if the car is running rich or lean. It then adjusts the fuel injectors to keep the emissions at a minimal level.
Sounds like the injectors are failing by staying open too long. Probably time for new injectors. Impossible to test without an inline injector tester. Hope this helps.
Exhaust leak, muffler is a louder type, improper instillation, etc.Exhaust leak, muffler is a louder type, improper instillation, etc.
have you tuned it up? plugs, wires, cap + rotor
Better air intake, better exhaust, install headers, change out your fuel injectors, add a bolt-on turbocharger, have the ECM reprogrammed.
A whole lot. You'll need to replace the intake, redo the exhaust, replace the injectors... there has to be a precise fuel/air mixture in these engines.
On the 3.4 V-6 Chevy Malibu the thermostat is located at the rear of the engine. The exhaust cross over pipe that goes between the exhaust manifolds makes the thermostat housing hard to access. The easiest way to change this thermostat is to first remove the exhaust shield and exhaust cross over pipe, then the t-stat can easily be changed. After changing the thermostat, be sure to bleed the air from the system, look for bleeder screws and run heater until air blows warm.
intake, exhaust, fuel pump, and injectors there a number of bolt ons and theres always turbos and superchargers. http://www.lextasy.com/IS300_intakes_ctg.htm ----
