SOURCE: car idles low, stalls after start

Common issue at the shop (i'm a ford technician), here is what I do to correct it.
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk 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: Black exhaust smoke from Jeep Cherokee 2.5 CRD

The smoke and the the bogging down are due to either too much fuel flow or to too little airflow. Your engine is flooding and running way to rich hence the low fuel mileage. Could be a faulty pump with too high pressure, bad or wrong sized injectors, (assuming they actually fixed the sensor problem) or airflow restriction,

SOURCE: Shaking engine, weak power, blinking check engine light

You have a bad coil pack, they usually crack from age and heat. It's best to replace them all. Check for a VW recall on this item.

SOURCE: 1991 Chevy Caprice has a mild miss fire and stall

Do you have the idle speed turned up to keep it from dying? Because it is high. Check engine light on? Have you checked for vacuum leaks at the gasket under the throttle body? How does the car run under acceleration? You might have a worn distributor shaft.

Make sure the hose connected to the PCV valve is connected at both ends and has vacuum. It is better to replace rather than clean a PCV valve as they are inexpensive. It sounds like your engine is building up internal crankcase pressure so a new PCV valve would be a good place to start. The "egg" smell could be that the catalytic converter/s are going bad and need replaced.

Remove your belt and reach down in there with engine off check make sure you can turn all pulley's with your hand make sure none are lock up, also see if you can turn front plate on A/C compr and hub bearing where belt ride's on.

1993 lumina euro is blowing black out of tailpipe smells gas


Black smoke is unburned gas. If the car is running fine besides the black smoke, it's most likely the Coolant Temperature Sensor. The part is roughly $20 and an easy fix.
