SOURCE: 1989 jaguar xjs v12 fuel mixture

Chances are the coolant temperature sensor or its wiring have failed, or the vacuum line to the MAP sensor is leaky or broken (I believe the V12 in '89 guise uses MAP sensors). The MAP sensor measures Manifold Absolute Pressure. Along with this pressure the ECU looks at engine RPM. It also measures air temperature. Knowing pressure and temperature we know density, and knowing engine speed tells us how much volume of air is going through the engine. All of this together is computed into air mass and is used to calculate how much fuel mass should be admitted. If the vacuum line is broken, the ECU reads less vacuum and produces rich mixture thinking that the engine is under high load.

Rough idle, misses ,,Engine hesitates,poor acceleration


typically these problems are caused by either fuel problems or spark problems. I would pull the sparkplugs to see if the engine is running lean or rich. Normally the spark plugs should have a nice tan color to them. If they are wet or black engine is running rich. Easier still depending on the year of your Blazer, is to have the computer scanned for codes. Usually this will tell you exactly what is wrong.

What effect would a dirty air filter have on my cars performance,could it cause my car to lose power on occassion ?


A car burns air and fuel mixture. A dirty filter will prevent it from getting enough air causing it to run rich. This can reduce miles per gallon, foul u spark plugs and contribute to premature engine failure. As for losing b power on occasion it's possible although not probable unless it's completely blocked. Air filters are cheap and easy to replace. No reason not to change it.

1991 Honda Accord, 213k, changed oily sparkplugs and now engine blows excessive smoke and oil continuously out the exaust from start up to shut down.


Old spark plugs were likely fouled with oil and not burning fuel (and oil) completely so minimal smoke before change out. New plugs are clean and burning everything in cylinders well including oil (therefore more smoke). If smoke from exhaust is blue, then engine oil is getting into cylinders either through worn out piston rings, or a leaking gasket. If black smoke, then this is a sign of too much fuel getting into cylinders and not all the fuel is getting burnt during combustion (a fuel system problem).

2005 3.5l some times smokes oil then stops


Smoke oil? For what your thinking that is oil? Smoke coming from the tailpipe is not good news, but does not necessarily mean the engine needs rebuilding. First, you need to determine what color of smoke is coming from the tailpipe
* White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.
* Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
* Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." 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.


If you confirm us that is oil smoke, check and keep in mind that the car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

My sparkplug keeps getting black, then the car begins to sputter


Car is running rich, can be a bad fuel pressure regulator or bad MAP sensor and can even be as simple as a bad vacuum hose that is disconnected. Regardless your engine is running rich (too much gas in to the engine from the fuel injectors) causing your plugs to turn black and foul, which is also causing your engine to sputter.
Start with the simple and check all your vacuum hoses, fuel pressure regulator and MAP sensor.
Good luck and keep me posted, be glad to help you get your car running 100% again soon.

My truck seems to be running to rich on fuel when starting after it is warmed up, cold starts are fine. 1999 gmc


There is a possibility that your temperature sending unit for the computer is not working correctly. ( not the sending unit for the gage, there are two). If the computer never knows that the engine warms up, it will keep "choking" and over fueling. Thus, the black spark plugs.
