First start by checking to see if the spark work and do not have a bunch of junk built up on them. If they do, clean them with a wire brush or replace them if they are real bad. If they do not, check the gap on the spark plugs to make sure that it is gapped right for the specific car. If those were not the problems take your spark plug wires off and use an ohm meter to check the resistance of the wires by putting the positive and negative wires of the meter on the ends of each wire. If one or a few of the readings are far from the rest you should try replacing the wires. BE SURE TO PUT THE WIRES BACK ON IN THE ORIGINAL ORDER. If all plugs and wires are fine check the coil packs to be sure they are working. Pull one wire off of the coil pack and have some one hold a grounded, WELL INSULATED wire close to, but not touching, the part the wire snaps on to the coil pack. Turn the engine over to see if it sparks. KEEP HANDS AWAY FROM COIL WHILE TESTING. Believe me it doesnt feel good to get shocked. I know from experience. Do this for each wire on the coil packs. If one does not spark do then the coil pack is bad and needs replaced. If you have a car with a distributor pull the distributor cap off and check for cracks. If its cracked it needs replaced. This is as far as i have ever had to go so i hope it works. Good luck.

Feels like miss firing at higher speeds

Your caption says misfires at high, then you say low? You have a 95. Lots of miles I assume. So there are several things that would cause misfires at high and low. First is timing chain/belt, sloppy. Second, would be the valves and rings. Valves worn or bent, not seating right. rings just worn out, not holding compression. Do a compression test and see. Low speed or idle misfires can be from vacuum leaks. check hoses. Low and high rpm misfires can be from ignition problems. Wiring, coil/s, ignition modules.

Engine Misfire diagnosis can be complex and there are many reasons for misfires to occur. I suggest you read the article at this link that deals with engine misfires and the diagnosis of them and possible solutions to repair them.

I stepped on the gas the car took off then immediatley slowed in power. The engine light came on and started blinking. I could drive the car, but only at slow speed. 2007 Mercury Milan V6. Any ideas

when the check engine light blinks this is a sign of misfires but your going to need a scanner to determine which cylinders misfired and clear fault memory i would then recommend swapping coils and plugs from cylinders that misfired with ones that didnt and see if misfires migrate to determine bad coils or plugs

Try spraying an aerosol oil around the intake manifold and around any vacuum lines and connections with the engine running. If you hear a change in the engine speed than you've got a vacuum leak. Thank you, Dana
