I have an 81 Lincoln mark vi that sat over the winter (4-5 months). It's starts right away sometimes but I figure it's the cold weather. But while driving g it lacks any get up and stalls when coming to a stop or when reversing out of the garage. I stepped down on the gas while park to maybe clean it out a little, it just backfired and seem to maybe have gotten worse. Just had a tune up before sitting and is kept plugged inside the garage. What could be the problem?

What about the stalling. I was thinking a new carburetor. But want a second opinion before spending unnecessary money.

I am giving you a walk through for stalling. Go through it first. If you don't find anything have your fuel pressure checked and replace the fuel filter. Use the link below;

LOOK THAT PUPPY OVER REALLY GOOD FOR VACUUM LINES PULLED OFF/ BROKE/ SPLIT. EVEN A CONSTANTLY HISSING BRAKE BOOSTER IS A VACUUM LEAK!

WHEN YOU SAY TUNE UP. WHAT WAS DONE. PEOPLE'S VERSIONS DIFFER.

WAS IT ALL PERFORMED BY A PERSON FAMILIAR WITH CARBURETORS. IS THERE ANYTHING THAT WAS RE ROUTED OR REMOVED?

WERE THE CARB ADJUSTMENTS MONKEYED WITH?

AN ENGINE ONLY REALLY NEEDS A COUPLE OF VACUUM LINES TO MAKE IT RUN. THE REST ARE FOR EMISSIONS AND ACCESSORIES ON THE VEHICLE ITSELF. LIKE THE HVAC CONTROLS, POWER BRAKES, ETC

THANK GOODNESS I HAVE JEEP CJs.I HAVE ONLY 3 ON MY '77 NOW. PVC/ DISTRIBUTOR ADVANCE/ AND A VACUUM GAUGE ON MY DASH THAT I MONITOR ENGINE CONDITION WITH. AND PLAY THE GAME: "KEEP THE NEEDLE HIGH (ACTUALLY MEANING LOW!)" BY ALTERING MY DRIVING HABITS TO MAX MY MPGs

THE REST OF MY JEEP IS MANUAL OR MECHANICAL. SO EZ TO MAINTAIN FOR AN EVERYDAY DRIVER. HE'S ONLY 37 YEARS OLD, MY WILLYS IS 68

ARE YOU CAPABLE OF WORKING ON THIS YOURSELF? (LIKE KNOW YOUR WAY AROUND IN THERE)

DO YOU HAVE A VACUUM GAUGE----A TIMING LIGHT---A DWELL/ TACH METER?

IT WOULD BE MUCH EZier TO ASSIST IF YOU HAD A CJ, I'LL STILL ATTEMPT TO AID YOU WITH THE FORD (THEY WERE MY DAD'S CHOICE), I GOT BROKE IN, WITH THEM, GROWING UP

Vacuum leaks and engine vacuum should be covered in the walk throughs. One good way to find leaks is to not only listen for the sucking noise but get a piece of thread and drag it around areas where surfaces meet. Meaning where the carb meets the manifold or any other area that needs a good seal. It will pull the thread towards it.
