Possible causes are as follows, I suspect you have an intake air/vacuum leak or a faulty MAF sensor. - Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

SOURCE: Where is the air cleaner in a 2007 Honda CR-V

Standing from the front of vehicle look in the engine compartment, on the right side of engine and behind the batterry. There is a black box with a 3" flexible hose hook to it, pop up 4 clips and remove the cover then you see the air filter inside.

Did you re check for new codes after o2 replacement? Does the idle hunt (up and down)? Have someone check the EGR valve.

Try to give it a little time because you just did some work, it may need to burn out... but black smoke is an oil burning problem. even though the car will still run you dont want this problem because if oil is burning in your engine, it means oil is getting where it does not need to be witch HOPEFULLY, is just a gasket but you are not just burning fuel so it may be affecting your gas mileage!. it sounds like old gaskets!? maybe? gaskets are a **** to replace especially in a civic, and they are everywhere! i know i just took the whole engine apart and put it back together again in a 95.

As far as the heavy exhaust smell... may be a leak or crack in the manifold!

And as far as your sensors and dash lights go, save your money and dont replace any more! especially if you smell a problem and are getting only 20 miles to a gallon (especially in a honda) because the sensors are probably right!

No power under acceleration 2001 chevy impala,ive added injector cleaner , cleaned maf,also checked cat ,seemed good, also replaced map sensor

well it is a chevy, its always had that problem. Haha, just kidding. But, seriously, it can be something as simple as a clogged air filter. I did all that you did on a car I had, and then, I replaced the air filter that I thought was good (reusable K&N) and it ended up being that. Try the air filter. Either replace, or clean it.

Three areas you should look for: o2 sensor, MAF sensor and the EGR valve. Try cleaning the EGR and MAF and also clean the fuel injectors using injector cleaners. This should solve your problem. If required, also replace the air and fuel filters.

After the fuel injectors were cleaned and fuel filter replaced the honda is runing rich. what can this problem be?

Probably a very dirty air filter and Mass Air Flow (MAF) sensor. Replace your air filter, and clean your MAF sensor with MAF cleaner. You can find it at any auto parts store. Disconnect your battery for about 10-15 minutes to reset your computer. This will allow the computer to "re-learn" the settings with clean injectors and air filter.

My 2003 Honda CRV consumes excessive Fuel and also Its check engine (MIL) is ON. What can I do?

It sounds like you just need to replace the air filter. In my Honda, a dirty air filter would cause both of those problems.
