1978 Mercury Cougar 351 Windsor 5.8L

Summary:

It's a great all around vehicle, power, handling, and comfort

Faults:

I got the car with only 72,000 miles on it, The only thing that has let go with it is the thermostat and the radiator, which was bad when I bought it.

The seats are in excellent shape no rips or tears at all.

General Comments:

All in all I think it's a great car, it moves pretty quickly and rides beautifully.

It's a little hard on gas, but you have to take the good with the bad, I guess for having a 351 Windsor and weighing 5,700 pounds it isn't too bad.

It has all white leather seats, with red carpet and dash panels.

The door panels are also white, Also in great shape.

1978 Mercury Cougar XR7 302 5.0 liter

Summary:

This car is the greatest car I know ever built - very reliable and I love it

Faults:

This car was given to me by my grandfather when he passed away. Now I am 17 and I drive it almost every day. We had the engine rebuilt at 100,000 miles.

My dad just recently put a new carburetor in it, about 2 years ago, and whenever I first start my car, whether it is summer or winter, when I hit the gas down to the floor quickly it goes high then goes low like it will stall, but comes back up again. After warming the car up for about 10 minutes, I go to drive it. When I floor it while it's standing still in Drive and hold the accelerator down all the way, it stalls out completely. When I do the same thing, but let go it comes back up to a normal idle. This does not happen if I let it warm up for at least 15-20 minutes. My dad told me they call this a "cold spot". Can you tell me how or why this is happening and how to fix it please?

I have a 78 Cougar XR7 with a 351W (Autolite 2150 carb.)

Check the following for stalling.

First, make sure choke thermostat is adjusted properly.

Temporarily disconnect the vacuum line to the EGR valve and plug it. If the EGR valve opens to much, the car will hesitate. Check your accelerator pump in the carburetor.

Make sure it is pumping. There is an orange plug in the carburetor that could be your problem. If so you need to buy a rebuilding kit using the carburetor identification tag located on top of the carburetor.

Make sure you do not have any vacuum leaks.

Also, check the plunger adjustment on the accelerator pump. You may need to tighten it up by bending the pump rod at the Z-bend just a little to take up the slack.

1978 Mercury Cougar xr7 351M/400

Summary:

Cool and laid- back

Faults:

Front rotors and brakes needed to be turned down and replaced.

The guts in he rear end had to be changed.

The passenger side axel was bent.

Rear bearings also had to be replaced.

Tail, signal and back up lights had to be rewired.

General Comments:

Many things were wrong with the car considering it was only bought for $400 Canadian.

I have made a few modifications to the car.

Since ownership I have had the body redone and painted. I elected not to go original, decided on 97' prowler purple.

Added mag wheels and circular chrome mirrors.

A hood scoop was a must, also added chrome to the hood off of a 61' Buick.

This summer I plan to tint the windows and add two white stripes on the hood. Also will have the chance to put the chrome duel exhaust on that I purchased last year.

Over all is an excellent car. I just hate the gas mileage you get with.

1978 Mercury Cougar XR7 6.6 litre -400

Summary:

A gas guzzling hog, with a lot of balls

Faults:

I have found that the Mercury Cougar is a very reliable car. The only problems I have had with it are the power steering, which was only a hose needing replacement.

The only other thing I have had a problem with is the lifters. I plan on rebuilding the motor in the near future anyway, so it's not really an issue at this time.

General Comments:

This car is a very fast car, especially with a 400 in it.

However the car is a boat, and uses a lot of gas.

I only payed $1000 for the car and have all the original paperwork for it (which is a plus).

I'm thinking of new ways to better the car and would like all the input possible.

If you have any details on engine accesories please e-mail them to me @ cougar 78 XR7.
