It's debatable whether the oil caused the plugged cat, doesn't matter at this point. If you have doubts about the plugged cat diagnosis, you could remove the O2 sensor and drive it to see if this helps. With O2 sensor out, it will be noisy as heck, but it will relieve enough back pressure to give you more power and confirm the problem. Cats are expensive and a pain to change, I would go around to a few muffler shops and get quotes. Go with the guy who seems to have the best price/warranty/service...etc.

To diagnos the catalytic converter, remove exhaust Y pipe from exhaust manifolds and start up. If engine runs goood and revs up, then suspect a restriction in your exhaust. Exhaust shop should be able to fix the problem. Cannot repair the cat converter. It is a honeycomb of metals inside that superheat the exhaust and burn off any unburnt fuel. When the honeycomb melts from contamination then it blocks exhaust air flow.

The converter cannot be repaired only replaced. Shop around at different auto parts stores, then check local muffler shops to find your best deal.

1992 mercury grand marquis how do i know if i have a blown head


If the head gasket is blown you will have either oil in the antifreeze,antifreeze in the oil or white steam out the exhaust and your antifreeze level will be low all the time.sounds like you may have a clogged catalitic converter to me.

You need to put back converter. The car needs it for its resistans. No converter makes presure go down in the detonation chambers.So due the loss of power, engine consumption is increased, to compensate that. Some cars wont ewen start without catalitic converter.

You could try another oil pressure sensor or test the oil pressure with a gauge at the sensor port. If you think about it, the truck goes into a failsafe mode when there is a problem. You could go into failsafe with high temperatures too. The water temp sensor could be bad but with the oil light coming on, the oil sensor should be your first choice.

You can get a free scan at Autozone or Oreillys and it may show the problem. Sometimes it takes a better scan with dealership type diagnostics because the self-diagnostics on your truck is limited.

Failsafe mode would cause the power loss because the truck is designed to kill cylinders and to use the dead cylinders as hot exhaust pumps to cool the block.

I need a timing digram for a 1995 isuzu rodeo. i was told that the timing is off causing loss of power and poor fuel mixture


i need to know some things first.. you may not need the timming diagram. does your vehicle go still shift when you drive and does it go up hills at normal rate of speed or does it loos power and only go about 30 to 40 MPH. if this is what is happening than you need to check the catalitic convertor it may be clogged. my 94 suburban did this same thing and i replace hundreds of dollars worth of parts on it and nothing worked and this is what my problem was. you need to take the catalitic converter off or loos at the front of the engine and find out if this helps or fixes the problem.
please let me know

Nizzan 02 Black smoke coming out tailpipe and consumption of oil


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.

Loss of power on acelaration


There's a lot on any car that can cause loss in power.
A few of them are:
Mass air Flow sensor
Bad O2 sensors
Old oil or sludged oil
Bad Gas
Clogged catalytic converter
Loss of cylinder pressure or compression

I would start with the cheapest tests/fixes first
oil: if you haven't already and don't know the condition of your oil, change it. If your oil has sludge in it then you could have a leacking head gasket.

Next up, If your gas is bad fill the tank about half way and use lucus oil octane booster, and for a second half a tank pour in some seafoam engine cleaner. It will clean your fueling system, injectors, and pistons/chambers.

If those too don't help: get a compression test on the cylinders. Not expensive to have done, but could be expensive to fix if there is something wrong or the compression is leaking.

Next, go to a muffler shop and have your catalytic converter checked. A clogged or bad Catalytic converter may trap exhaust and keep it from exiting your exhaust system.
While your there you can have your O2 sensors checked.

If all of that is fine, replace the O2 sensors and the Mass air flow sensor. These components control the air fuel ratio. If they are going out your engine won't ever get the right amounts of gas and air to run properly.

It's a lot, but my general rule of thumb for trouble shooting any issue with a car is to start with the cheapest fix and work your way up.
