what color is the smoke? What does it smell like? Whats your oil level? what color is your oil and coolant?what type of gas do you normally fill it with?cars will smoke for numerous reasons. If youre getting a sweet smell from the exhaust, its going to be a coolant issue, If youre getting a rotten egg smell, its going to be spark/fuel/timing/ coolant issue, if youre getting white smoke, its going to be an oil/coolant issue, if youre getting black smoke, its going to be a fuel issue.start by determining what color or smell the exhaust is. Then pull the diagnostic codes to see if you have any problems. Pull up the passengers side kick board and look for a small loose wiring harness connector. Its going to be blue/grey/black/green. Stick the end of a paper clip in one hole, then stick the other in the other hole. Now, turn your car to the 'on' position. if you have codes, the check engine light will flash. 'flash' flash 'flash' pause 'flash' is code 31next, check the coolant. If you have brown oily coolant, thats not a good sign. It could be a broken head gasket, or more serious, a cracked head (which would require basically a new engine).If you have brown chunks in the coolant, this is much easier to fix. Youre basically going to have to flush the coolant system. The easiest way is to use a garden hose.while youre flushing the system, check the thermostat. boil some water then stick the thermostat in it. if the thermostat doesnt do anything, replace it, if it opens, its fine. check the oil. If its creamy, its going to be one of the previous problems.if the oil is fine, and the coolant is fine, the next thing you want to do is flush the oil system. Buy a gallon or so of kerosene, drain your oil, change the filter, pour the kerosene in the oil cap (the amount of oil youre car will normally take), start the car and run for 20 seconds. Shut it off, drain the kerosene, then fill the car with oil, run for a few minutes, then drain the oil, change the filter, and put the new oil in. The kerosene will clean any carbon deposits (and unburnt fuel if you use regular) that may have built up. Its exactly the same as 'engine flush' sold at any auto parts store, but 300% less.So, do this, then see if its still smoking. If it still is, then youre going to want to run a compression test. This requires a bit more mechanical abilities, and speicalized tools. You can rent them at autozone, and they come with a book to explain it.obviously, if you arent caught up on recent maintenance then it could be numerous other problems. But if youve changed the oil on time, replaced the spark plugs/wires in a normal schedule, clean or replaced the air filter on a regular basis, then those more then likely wouldnt be the cause.and sorry i wrote so much, i have no idea what your current knowledge of autos is.
