Could be just about anything, but given that I had the same symptoms that turned out to the fuel pump, I would check that if you haven't already. Mine would run fine for a while, particularly when it was cold, and tested fine at the shop, but after a while under load, it turned out the pressure would suddenly drop to about 15 pounds. A real pain to diagnose, since when it was in the shop it wasn't under load, so it tested OK.

SOURCE: My 99 mercury cougar v6 is stuttter when i drive

I had the same problem, but the problem didn't start until winter when it got below 0 degrees celcius. it would almost bronco jump and stall at stop lights, (almost rear ended a few people...not safe at all) and then when i'd start it up, i'd rev it and it would stall...but still starting again everytime.. it turned out that.this car is really good and developing condensation in the fuel line/tank...I went and bought a 2 dollar bottle of gas-line antifreeze (any gas station) put it in with the gas and filled 'er up with a tank of premium (cause it burns hotter) and the problem was solved almost instantly. (after about 20 minutes of driving) it saved me from having to get my entire pump replaced...try that out..if it is only since winter started(i dunno where u are) it could very well be your problem.

I will be driving my 87 cougar down the road then it will start jerking lose speed and die. what is causing that?

here are a few symtoms of a BAD IGNITION COIL. the car will spit and sputter.
If your vehicle is getting a lot less mileage for the gallon, you can also register this as a sign of ignition coil failure. When less power is reaching the spark plugs, your vehicle will struggle and use more fuel to compensate for the lack of power transfer.
Engine Misfiring Trying to start your vehicle when the ignition coils fail will result in a rough ride. Your vehicle will cough and splutter regularly and when you drive at higher speeds, your vehicle will **** and spit. It will also vibrate when you are running idle at a stop sign or intersection.
Vehicle Stalling With ignition coil failure, your vehicle will have irregular sparks emitting to the plugs to keep it running. This will result in stalling. When you bring your vehicle to a stop, it may just shut off totally, thus leaving you needing to restart it.
Coil Failure If your spark plugs are worn out, it forces the ignition coils to operate at a much higher output. Keeping your sparks plug in optimum condition can reduce your chances of having ignition coil problems. Some simple regular maintenance will save you a lot of grief. hope this helps you out !

I have a 1987 labaron with the 2.2 non turbo. It will take the gas going down the road if I floor it but wont if i try to hold at a steady speed.

Check throttle position sensor. TPS. Over time they"ve been known to develop a dead spot which usually will appear where you would normally have accelerator when driving normally, I would suppose due to repitition wearing it out at that area. If you have a multimeter (analog- needle) style, you can test it and watch needle for stumble, or drop off when moving throttle smoothly up and down.

87 Mercury Cougar V8 5.0L, The car when going

There is something out of balance or loose or the car could not shake. Take it to a front end shop where they can check the toe and camber and check for bad wheel bearing etc. Shaking at the speed usually means a tire has a bulge or out of balance. Good luck you need a second opinion. This could be dangerous too so don't take any chances.

Over-revving in 5th at 75mph all of a sudden

If the car rev'd up but did not speed up at the same time the clutch is starting to slip. Check the adjustment and recheck driving. When the clutch starts to wear this is how they act, only most people ignore whats happening and keep driving till adjustments won't fix it and the clutch has to be replaced. Have adjustment checked and keep an eye on it and hopefullty you won't need a clutch yet.
