Will any light come on when it's messing up? If not, you might have a problem with the ignition lock cylinder (where the key goes) or the ignition switch (the electrical part inside the steering wheel). Good Luck!!
most times it is a bad coil pack there are three ignition coils mounted on top of the ignition module. one coil supplys 2 cylinders with spark. original coils have the cylinder number stamped on the coil so you know what coil feeds #y cylinder. 80 percent its a coil failure 20 percent the module fail and signal is interrupted to coil.if you don't want to just change coil.without proof,you can switc coil with another remember to mark the number of the cylinders on the ignition wires before you switch coils as the coils have a firing order that must be followed. when you switch coils and test drive check the coses for misfire again if the miss moves to a different cylinder number the coil is bad. if the number is still four with the coils switched,the ignition module if probably bad, these coils usually tes good when you ohm test them but these coils usually break down under engine load and heat,your coil can pass a ohm test but still be bad. there cheap enough just put new #4 coil in it. p.s you need a 5.5 millimeter socket to remove coils

How do you get to the back three spark plugs on a 2001 Buick Lesabre?
Its a pain but not that bad. You don't have to move the engine but it might help. Go to Harbour Freight and get: (1) A stubby fine tooth ratchet wrench (2) They also sell a regular size ratchet you can slide out and extend (3) a short extension (4) a swivel (5) A $3 plastic wire boot puller. Using one or the other or a combination, you can reach in from the left side of the car just under neath the alternator and get to the plug wires and plugs on two of the back ones. The farthest one away from you, you have to go in over the top. You can carefully find a spot to sit on the engine and get that one. You'll need to use the stubby and have a little arm strength to get them undone. One tip on removing spark plug wires is to grab them as close to the engine as possible and twist back and forth about 1/4 inch to break free the rubber gripping the insulator. Then use that handy dandy Harbour freight boot puller to get it off.

Why will the power windows on your 1997 Buick Skylark go down but not up?
The tracks that the window rollers ride in are guncked up with old lube and dirt. I just cleaned the tracks out and lubed them with a light grease and my windows worked again. The window motor heats up and quits is the problem. If you don't attend to this you will have to spend up to $300.00 per motor plus labor to replace.
Probably because they're in the first stage of conking out entirely. If they go back up or partway up after you let them "cool off" for a few minutes, that's the problem. Replacing the motors is the only fix, there's no repairing them. But parts stores should have them.
Some small cooling systems can be quickly overcome by cold air rushing thru an open grill; This is why you will sometimes see 'winterfronts' on some vehicles. Even cardboard in front of the grill will help.Make sure your radiator is full; even if it is a little low it will make a huge difference in it's ability to maintain heat as cold air rushes thru it. I hope this helps you. Mark

How do you repair the brake interlock system in a Chrysler Pacifica It's stuck in PARK?
Possibly the brake light switch is bad. I had a recall on a Ford Taurus that spoke of this problem. The brake light switch releases a solenoid that holds the shifter in park.
It's probably telling you there's a potentially dangerous brake problem on your car. You definitely want to investigate. It could be something as simple as stuck or overly tight parking brake cable too. But if you're not comfortable doing brake work, take it to a shop ASAP.

Does a freon leak keep the compressor from coming on?
The short answer is yes. There is a pressure control that will prevent the compressor from running and damaging it. There are other reasons so it would be best to let someone who knows their way around auto air conditioners check it. Air conditioning systems can be very dangerous to mess with, if you don't know what you are doing. even without the engine running. As a novice mechanic 40 years ago I almost broke my hand taking apart a compressor that I thought was without any freon.
