Is catalytic converter the problem?

[landoland]

is catalytic converter the problem and if it is, how about universial cat?

My mechanic told me that the issue was with the catalytic converter that it seem blocked up i notice he put his hand at the muffler and came to the conclusion that the cat is blocked up because he can barely feel anything coming out.

The car keeps jerking like the egine wants to kick off while its in park idle or if i stop and in drive and just simple on the breaks.

I can barely get the car to go to 80kmph i have to press out and it takes forever to get there while the car keep giving off a missfire feeling as if the engine is rolling over. No engine light on actualy no light ont he dash on.

Is the cat really the prolem and if is, how about universial cat and which is the best universial cat to use? correct me if i am wrong but from my understanding the actual cat itself is no difference from the dealer cat except will have to cut the old one off and well the universial.

Thanks in advance.

When you turn the key to Run, do you get all the appropriate instrumentation lights to come on (bulb test)? Does the Check Engine Light come on then? If so, it seems odd that you would not get a check engine light with a plugged catalytic converter. But, what you describe does seem to point to a bad cat.

What you'll want to do before replacing the converter with either an OEM or a universal is determine why it failed. Rarely do the converters fail due to age. Typically you will have an extended rich condition that will accelerate the converter destruction due to overheating the converter trying to convert all the unburned fuel to water vapor.

I can't really comment on if a universal will be a suitable alternative in this application.

You will need to determine which cat is the plugged though, your car probably has 3 of them. And you will likely need to clamp or weld in the universal fit converter.

Thanks very much for the information shorod and fast respond. i understand that the universial will have to be well in already however what i am concern about is the cat itself besides size and fit what about requirement in other words how would comparing a original lincoln cat to a magnaflow cat in quality result?

That's the part I cannot comment on.

what would you say about this one its a direct fit.

Some good info.

When your Lincoln catalytic converter begins to fail, you will face dropping fuel mileage, poor driving performance and the risk of failing an emissions test. Your catalytic converter will usually fail when another component in the fuel/emission system stops working, leading to a too-rich fuel mixture in the exhaust. When unburned fuel ends up in the catalytic converter’s very hot core, the fuel will ignite and raise the temperature levels further. Over time, the catalytic converter will suffer heat stress. The too-rich fuel mixture can be caused by failing fuel injectors, oxygen and other sensors. If your Lincoln’s combustion system suffers from repeated misfires, unburned fuel will be sent into the exhaust system. So check for misfiring spark plugs, ignition leads and distributor caps to trace the cause of the misfires. Diagnosing whether the catalytic converter can be tricky. First, check the onboard diagnostic codes for any clues. Tracking the temperature levels at the front and end of the catalytic converter might provide clues. Use a laser pyrometer, which measures very high temperatures to check the heat levels of the inlet and outlet. If the cat is working correctly, the inlet will be much hotter than the outlet. Sometimes the catalytic converter can become clogged with leaking oil and coolant from the combustion system, so check for blockage with a pressure tester. Once the diagnosis confirms that you need a new catalytic converter, purchase a quality unit from our site.

Seems like a good option if you know which converter is bad (left or right) as well as why it failed (like I mentioned in post #2 above).

i think both of them fail and i think the reason is repeated missfire. at first missfire oil leak in cylinder 3 and the guy that pulled it up only change the plug thats it so pretty much the missfire happen again because he did not fix the reason causing the missfire which was to replace the rock and cover gaskets inner and outer i think. i bought them original from lincoln dealer and did a full service changing those when the second missfire occure, base on the information i found it seem that repeated missfire is possible reason why cat fail and seem both of them fail so both need chaning.
