1982 Mark VI Performance Issues

Bill -

I don't drive my 1982 Mark VI anymore, and days between short drives of just a few miles in town. Started noticing the idle increasing 8 months ago slowly over time, and the speed it wanted to go increased as the engine warmed up and then suddenly work fine after off for 30 minutes sometimes. Then a week ago I started it up and it started bucking and didn't want to run in gear, but as the engine warmed up it got a little better, but when I stopped for a few minutes at a store it didn't want to restart, even with it spinning fast, so I floored it and it sputtered to life, and I got home. Days later it started fine but acted the same way, but then at the same shop on restart no sign of trying to start, even floored. Towed it home and the next day today it started fine again but acting the same way. I am suspecting the EGR was sticking some, and now a lot. What would be your guess?

Greetings Dwight -

Could you forward your customer number so that we may look up your account with us? Also it would be helpful to know the tune up history of your Lincoln and what you have done so far to diagnose or correct your engine issue. The engine management system for your 1982 Mark VI engine was sophisticated for these early years of automotive electronics and therefore requires a shop manual to assist in pinpointing the culprit in a logical sequence. If a component such as the EGR is suspect for any reason, it should be tested as per the manual before replacing. "Guessing" is not a wise option. Do you have a shop manual or do you have a mechanic that has a factory shop manual along with some technical experience with these vehicles?

There is not an over abundance of Lincoln collectors who collect these early 80's years of Marks and many parts are becoming difficult to locate as time goes by. In your case there are some on going on line forums available for specific eras of vehicle whose members may have had experience with your exact issue and similar engine management problems.

Sincerely,

1989 Town Car Shifting Question

Bill -

I just purchased this vehicle and had the engine professionally replaced since the previous owner overheated it and blew the heads. The transmission was also serviced. I was driving it and noticed that shifting from first to second was fine but from second to third there is a delay where the RPM's go up before shifting smoothly into third. Is this a normal function of that transmission type?

Greetings Robert -

What you are describing is certainly not normal behavior for that automatic transmission. The best advice is to take the car to a trusted transmission shop and have it road tested and evaluated for a possible internal transmission problem. A good transmission mechanic familiar with that era of Lincoln will also be able to ascertain if the transmission linkage and controls etc. were assembled and adjusted correctly during the recent engine replacement and transmission service.

Sincerely,

Bill

1967 Continental Starting Issues

Hi Bill -

I am working on my 67 Lincoln 4 door Sedan with the 462 engine and am having starting problems. I should say that the car is mechanically fully rebuilt and ran great, but was sitting for a while and now it seems that the gas in the carb drains back into the gas tank or disappears somehow, because the car wont start for a while till the carbs fill up and then it runs fine with no dying or hesitation - that's what it feels like. Any advice would be greatly appreciated.

Thanks,

Fred

The modern ethanol fuels tend to evaporate quicker than the fuels of the sixties. The fuel cannot drain back into the fuel tank. I would first do a complete fuel system test. This will include a fuel pump pressure and volume test as per the shop manual and an inspection of the fuel lines hoses and possibly the fuel pickup in the fuel tank. The fuel pump must supply the correct volume and pressure in order to fill the carburetor quickly on an engine that has been sitting for a period of time. The pumps can be weak and/or the push rod that operates it could be worn to less than the necessary 4 and 13/16 " to operate it properly.

1994 Continental Wiper Issues

Bill -

When the wipers are on Full does it still run through the intermittent Governor. My wipers stop after 10 minutes of driving, kick back in 10-15 minutes later. Today they did not kick back on. I opened the hood and when I closed it must jarred something because they started to work. What should I check as it is intermittent.

We usually diagnose these issues as per the shop manual. In your case and as a start, an examination of the hidden wiper linkage first for debris that has accumulated could be a good idea. Next would be to check for loose electrical connections at the motor etc. Be advised however that we do not have too many parts available for this year and model of Continental.

Sincerely,

Bill
