84 Lincoln Mark VIII stalls

1984 LINCOLN MARK VI

Hello,

I just bought my car and did a basic tune-up and noticed even afterward that it will sometimes stall. But only when
almost stopping. Like-- if I am coming to a red light about 15% of the time it will stall. Oh. Also once when I cleaned it out and left it running and I was going into reverse it stalled.

I hope it's nothing too big. The car has 81,000 miles and was kept uptodate. It really looks like it was driven off the lot yesterday. I really don't know alot about cars but I know enough. (I installed my own system and did my own tune-up so I hope this is something that I am able to fix myself.)

Well- Thank you all in advanced and I will be checkin' back in often; and feel free to ask questions. Also, does anyone know about how much MPG I have? (Cost me 45 to fill and I think a 21g tank.) [Code:1:204b1dbf56]Just bought it last week and scared to drive it w/o fixing it.[/Code:1:204b1dbf56]

Congrats on the new hotrod. :) Need a little clarification to begin with. I do believe 1984 were MKVIIs not VIIIs. Or is it a different year? What engine?

An EGR valve that is dirty and not closing properly can cause stalling during deceleration. So can a few others. List what you've done so far along wiht the engine particulars and I'm sure you wioll get several things to check. :Idea:

Also. All I did was change the spark plugs. My friend told me that like-- everything under the hood looked new. (Which it does and by the looks of it. She was only driven on weekends)

Mark VIIIs had a 5 year production run from 1993 to 1998. They all came with 4.6 liter OHC V8s. I hqave a 96 crown vic with the same engine. Very dependable and decent gas mileage. I average about 18 mpgs with a 50/50 mix of highway/city driving.

If it hasn't been driven much it might need some road time. Start with a fresh tank of gas and some fuel injector cleaner. I like chevron with techron.

I would consider replacing some basic maintenence items. Do you have any service records for the car? A fuel filter, air cleaner, and maybe a new PCV valve.

Here is a link to some basic maintenece items and timetables. https://www.2carpros.com/kpages/maint_tips.htm

I'm definitely better with cars than computers. :)

Hello--

You know what! It is a Mark VII. I guess it has always been selective reading because I have always been in love with the Mark VIII's. But anyways-- I am still happy with it.
So-- what I can do is run the last tank of gas out and get some stuff to throw in the gas tank and go for a car ride? Sounds good for me. Just a tank of premium gas and some fuel injector cleaner's and that's about it? Sweet. I will be able to fix this myself. I was scared to drive it because of this. (Didn't want to make a mountion out of a moal hill.)
I'm sure my own car maintenance project's will give me a vague idea on how a car operates but they are nowaday's ran off computers and I built the one I am on and a netword admin for: www. Collutions. Com
. Anyways. I will do this and let you know how it's going. May be a week or so but. I will reply.
Thank you vary mch for the link and the time to respond. If it's this small I will paypal you a few bucks. What's your paypal?

Save your cash my friend. I appreciate the gesture but I enjoy car stuff quite a bit. You will need it for gas. The 1984 MKVII came with a choice of 2 engines, a 5.0L gasoline powered V8 or the ultra rare 2.4 L Straight-6 diesel.

My son has a 1985 Continental with the 5.0L engine. Not a lot of horsepower (140) but very dependable and long life engine.. Gas mileage is poor. He only averages around 13 mpg.

Did you receive any maintenence records with the car? If not I would consider what I recommended in my prior post. Replace those items and if you still have driveability issues consider replacing the distibutor cap, rotor, plug wires, and also the O2 sensor.

Here is a good read on the early Mark VIIs.
