Hi, I believe your accord is fuel injected, which means there is no idle mixture screw, all adjustments are supposed to be made by sensors and monitors. That's great when everything is working as it should, but complicates things when something is not in sync with the rest of the system. If your accord is fuel injected, you have a ECU (electronic control unit) that controls the function of the fuel injectors by electric signals sent to it by sensors and monitors. Unfortunately, it sounds like you need a good garage or dealer to run some tests on the accord. Do you have emission testing in your state? If yes, how did your car do? Good Luck, Countrycurt0

I got a tata 407 turbo but the performance is poor it also smokes black and the fuel is black can some please help


Best I can tell this is a diesel truck? I know diesel, but
depending on age could be injectors, possibly Diesel injection pump hopefully not. The fuel is black? Someone is putting old engine lubricating oil in the fuel tank. It will increase the problem of black smoke. It may also have a bad smell because of the engine oil. If the turbo is not spinning properly (high pitched whine) the bearings may be bad and it's not getting enough air into the engine. This would also explain the smoke problem. Take it to a Diesel specialist!

Black smoke is due to a rich fuel mixture, Check first to make sure you have a clean air filter. If you have a MAF Sensor or an O2 sensor going or gone it will tell the computer the wrong information and the computer will adjust accordingly. You can always use a code reader to see what codes you have, A parts store will have one to read a code for you. I have seen more black smoke from a restricted air filter than anything.

When first started black smoke comes out exhaust pipe,, what could this be


Black smoke is burning oil. Blue smoke is usually transmission fluid due to a leaking modulator valve in the older auto transmission. White smoke is due to water getting in to a cylinder from a bad gasket, cracked block or a cracked head. Black smoke from engines on starting and/or running tends to mean there is fuel leaking into the engine, or the fuel mix is incorrect and not atomised correctly. the main causes are normally a nakered air filter that isnt letting enough clean air into the engine to mix. a blocked fuel filter, which is either not letting enough fuel in, or in some cases, a faulty fuel filter which is letting too much fuel into the engine, and causing black smoke due to excess burning. Black smoke is a fuel/air mixture suggestion problems with injection or carbonation. Cause of black smoke is due to running rich in the fuel air mix. Check the oil,the oil leak,the air filter,the fuel pump and fuel filter to confirm the fault.

1 what kind of oil add to engine. 2 there is smoke , is it carbiratur problem? thank you


Smoke can be caused by a rich condition in the fuel mixture ,oil burning, or anti freeze burning . The cause of these issues can be many. Start by checking your fluid levels. First you mention oil, If you do your own oil changes , buy your oil buy the case and carry a quart in the trunk in a plastic bag. Use any oil that meets the requirements of Toyota. All the oil is so much better now, than when your car was built , almost brand with a current rating (SJ, SK,SL,etc) should work fine. If you take out all your spark plugs and inspect them, you can tell by the color and deposits what is making the smoke gas, oil , or anti freeze. You may even be able to tell if the problem is isolated to one cylinder. One other thing to check , see if your air filter is plugged . That might cause the smoke (more fuel than air). Running a fuel system cleaner in the tank and cleaning the carburetor throat with carb cleaner may also aid in proper running.

I was driving on the HWY today and my car suddenly lagged and started puffing black smoke. Even when gearing down. Got towed home and now when I start the car, it sputters and has what sounds like a slight...


I would do an oil change first and double check to make sure the oil is always at top level without over filling it. If the problem persists after that, then check your air filter, fuel filter and spark system.

Black smoke is usually caused by a bad oil seal, clogged air filter or fuel problem.

1994 Lincoln Town car idles while sitting and smokes. Won't pass inspection. Any suggestions?


is it blue or black smoke?
if its blue smoke you have a worn engine / overfilled oil....
if its black you may have ignition trouble/ fuel mixture problem...
test the sparkplugs and ignition leads first... check the oil level...
if you have any oily sparklugs i would suspect piston ring problem, or valve wear - could be time to install oil control rings (if applicable)

Black plugs would indicate an over-rich mixture or poor spark... replace the HT lead assoc. with the blackened plug, and the spark plug itself.. this may sort your problem for a few bucks.
If it's a piston ring or valve problem you need to overhaul the engine - or if you just want to pass the inspection then deal with the problem later you could use an oil additive such as STP "stop smoke", this thickens your oil and reduces the amount that will get past the pistons into the combustion chamber, in some cases it pretty much solves the problem - especially if the engine is in good condition apart from worn rings... But overhaul is always best, its upto personal choice in that respect and the size of your wallet.

My Corvette smokes a black sooty exhaust about half the time. I've driven it about 3000 miles in last 4 years. What is the problem and how can I repair?


Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor. Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil.

my 2001 Ford Windstar blows smoke and heavy drops of oil out the exaust, and usually only does it when it is cold and you first start it. The oil level in the crank case runs all out in two days and have to add four quarts of oil. What do you think the problem is?
