White smoke from the exhaust is usually an
indication of coolant in the cylinders, from a
possible bad head gasket or other gaskets

May be time to parts with it, when you find
out the repair cost

SOURCE: bad O2 sensor

I'm not sure about the rotor cap, but if it is telling you you still have a bad O2 there are about three on it. One up front and two back further by the catalitic converter..

SOURCE: '95 Honda Civic EX will not start after cleaning fuel injectors

I would talk to who cleaned the injectors, I don't know if it something they did or not. It could be a stuck open injector. The exhaust would have a raw fuel odor if it was. What it sounds like is a blown headgasket, which can just happen. The exhaust would have a sweet smell to it. Usually starts as a small leak (between cyl. 2 & 3), the engine burns the coolant while driving which you don't see. Then the coolant level gradually drops to a point where the car overheats, which warps the head, causing a large leak. Now you see the coolant burning (white smoke).
Good luck Honda Al

SOURCE: 2000 kia sephia constant engine stalling!!!

try this procedure and let me know if it cures the problem.

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: Engine turns over but won't start / 1995 F-150

Sounds alot like the ignition sensor. In my old Chevys it was under the dist cap, mounted on the dist itself. Mine was flat, slightly curved rectangle shape, with two flat prongs coming out both sides. If it would get an internal break in it, you cant see it. I would have the same problem as you, part was only about $12. And comes out with unscrewing two screws.
Might want to give it a shot.

SOURCE: 1993 Chevy S10 Blazer engine hesitation with smoke from exhaust

Had a 94 Olds Bravada that did a similar thing and it was EGR valve on the front of the intake. It' s easy to take off and clean with WD 40 and if you have an air compressor blow it out good.

Engine jerking


Most probably u have a spark plug coil gone bad or a spark plug wires.
But if not then then go through the following:-
  1. Check fuel filter or clean system
  2. Faulty or incorrectly gaped spark plugs
  3. Defective spark plug wires .
  4. Emissions system components faulty.
  5. Low or uneven cylinder compression pressures.
  6. Check as described in
  7. Weak or faulty ignition coil(s).
  8. Weak or faulty ignition system.
  9. Vacuum leaks at intake manifold or vacuum hoses .
  10. Dirty or clogged fuel injector(s). .
  11. Leaky EGR valve.
  12. Fuel injection or engine control systems malfunction.
I know it is along list but going through them will make a peace of mind to know which area is week and which is faulty.
Hope this Helps.

change main jet in the carburettor install K&N air filter and iridium NGK or DENSO spark plugs tune up your engine change oil filter and oil. Flush your radiator check tyres pressure, Check engine compression and air leaks from inlet manifold ,Run hi octane fuel and injection cleaner mix for 250k to clean the carbon in the cylinders ,check for fuel hose loose ,carburettor leaks,distributor cup aluminium contacts to be clean, Vacuum hose on distributor unit for suction for advance timing .

When i start my 2001 kia optima my car putters. i changed my bad o2 sensors. but not sure what the problem is. and when i drive sometimes it jerks. what could the problem be


The spark and fuel system needs to be inspected.--------- The spark plugs are getting fouled or very loose, can cause sputtering problem.Inspect the spark plugs and coil packs.The spark plugs gets power from coil pack.If the spark plugs are very old and dirty, then it needs to be replaced.--------------- The **** problem also relates to faulty worn out spark plugs or clogged fuel filter or low fuel pressure or problem with ignition coil pack.----------- When coil pack stops giving power to spark plug the car will **** while driving.---------- So very first thing you get tested is spark plugs and ignition coil packs.If they are tested good, but looks very dirty/ worn out, that can also be the reason.----------- But if spark plugs and ignition coil tested ok and cleaned properly, but still same problem, then get fuel pressure tested.If fuel pressure is low, the fuel pump and fuel filter are the cause of problem.----------- ------------------ Also one more thing, " IS there check engine light coming ON dash" ? If yes, then get the car scanned at autozone service center.Its absolutely free to get car scanned at autozone.They do it for no charge.------- In scanning you will get error codes, as per error codes, it will point towards faulty part, causing this sputtering and jerking problem.----------------- But if there is no check engine light ion dash, then get the above mentioned possibilities checked.That will help.Thanks.Helpmech.

I have a 2005 Ford Taurus. I got my car checked out at Auto Zone and the code said that the number three cylinder was misfiring. I have changed the oil, had a tune up,( new sparks plugs, fuel and air...


First off I think it's time for a new mechanic. Doing an oil change and replacing the fuel filter and air filter have nothing to do with a misfire. Spark plugs and ignition coils can cause a misfire, but a good mechanic will test the coil and inspect the plugs instead of just guessing. Your mechanic is guessing and just throwing new parts at the car. A misfire can be caused by (aside from a bad coil or plug) a faulty or clogged fuel injector, spark plug wire, wiring to the injector or a vacuum leak. Since you only have a misfire in one cylinder, and you hear a whistle on acceleration, I would suspect a leak in the intake manifold. Go to a reputable repair shop and have them check the manifold for leaks. You can also check yourself by buying an automotive stethoscope, and moving it around the perimeter of the intake manifold listening for a hissing sound. Or have someone press on the gas while listening for a hiss under the hood.

I have a 2006 Freestar with a 3.9 Engine . When it is cold it has a miss when i step on it. But it gets better when it starts to warm up. Almost seems like a spark plug miss


Spark Plugs ---change at 70,000 miles
O2 Sensors--change at 100,000 miles (front 2 only)
Gas Filter--every 3 years/30,000 miles
Air Filter ---every 3 years/blow off once every year
MAF Sensor---Clean once a year or more often

Ignition Coils--- most definitely will go bad,at
least 1 a year. (Any Check Lights or Codes ? )

When cold, it isn't in closed-loop, and runs on
Long Term Fuel Trim--not on O2 Sensors ,until
warm

Let it warm up at least 4 minutes in cold weather,
go light on the gas for first 2 miles

When at a stop light the car idles fine when i go to take off it sputters and back fires. I changed the spark plugs, but it is still doing it. It idles fine otherwise.


Does not sound like ignition, but fuel.
Idle needs little fuel.
Could be a clogged filter, water in the gas, bad pump, vacuum building up in the tank, bad sensors, etc.
Start with a gauge on the fuel pressure.
If it is low, that will point to filter or pump. Filter is cheaper to try.
If not low, then check the sensors with ohmmeter from Harbor Freight for $3.
There are O2, water temp, MAS, air temp, etc.

Misfire and low power, think its the o2 sensor because i already checked the plugs and wires, fuel filter, fuel pump, but i also havent checked the distributor cap or rotary button, could it be the o2...


First off there is no distributer cap or button. There are three individual coils. Instead of a distributer it is computer controlled ignition(spark).
Your service engine light should be on above your gas gage on your dash. You need to have the computer scanned for trouble codes. There are many components that may be causing the problem. Even if one of the 2 o2 sensors is bad there is probably something else causing problem.
