Depending on what year, I would say either the ignition coil or coil pack

You either have a coolant leak, a cracked cylinder head or a blown head gasket.  Take it to a mechanic you trust and have it checked out. It can only get worse by continuing to drive it.

Do you know any mechanics that will change the spark plugs from my diesel truck ? ?

Sparks not hot enough. Diesel fuel requires a very hot spark. Diesel ignites best under pressure. Gasoline would ignite with any spark. Do I want to know what you are using this for?

I doubt that just overfilling the transmission could have caused a metal-to-metal noise.  Take it to a reliable transmission shop and have it checked out.  There may be a much cheaper solution than changing out the transmission.

It could either be the starter or the alternator, the easiest way to find out without a lot of work is remove the alternator and take it to an auto parts store (most of them test them for free).  If it test out OK check the wire to your starter to make sure it has a good connection. If that is good then you can remove the starter and have it tested, not to hard to replace the starter but they can be expensive so it is a good idea to test it first, and maybe get it rebuilt.

go to www.allfordmustangs.com go into the tech department and look it up. I think it is under induction or Engine. Not completely sure. Hope it works. Good Luck.

A tune up to start.Plugs,spark plug wires,7mm will do fine.I reccomend bosch platinum plugs or split fire.For a budget,as I am on also,a new air filter will do,I like K&N.A good low restrictive muffler and a 3 inch exhaust will be suffice.You may want to check into a chip if your vehicle has a computer.Stay away from nitrous,your bottom end will not hold.Run a good 89 octane.This will not only improve your power but will also help your fuel mileage.If you want to get wild tear out all the interior and gut the thing to lighten it.You may want to also look into aftermarket undersized pulleys.Your looking at around a grand still at that.You may want to consider a trade for a mid eighties mustang with the 302.You could build a beast with that.Gluck man.Power up....

Check for these things:\n\n1)Fuel pressure...how high or low is it?  Low fuel pressure will do some of the symptoms you are describing, and can stem from a faulty fuel regulator or fuel pump (most fuel injected cars are regulated FROM the pump, so you are still looking at a bad pump regardless).  Some fuel pumps have what are called filter socks on them...these can sometimes get clogged as well, esp. if you live along a sandy area.\n\n2) Weak spark.  Biggest culprits of weak spark are old wires and plugs, as they increase electical resistance with age. Distributor caps and rotors wear out over time as well, so I  would (if haven't already) replace all of these items.  Least likely problem is the pickup sensor (though they will go bad over time as well).   \n\n3) Air system.  Make sure your air filter isn't clogged.  If the car is fuel injected, there may be an airflow sensor that needs replacing, and periodically cleaning the throttle body would be beneficial as well (smoother idle). \n\nHope this helps.  Hondas have a very high tolerance for lack of maintanance, so if it ran well before this problem, once all the items above have been addressed, you will swear you are driving a new(er) car!

there in the cylinder heads easiest way is to follow the spark plug wires down next to the exhaust manifolds..when the wire turns in, you found a plug....

you might just need a tune-up, or it could be more serious, try changing the spark plugs, distributer cap and rotor, a fuel additive wouldn't hurt either

i had the same problem with my 91 lumina with a 3.1 multiport, one of the cylinders wasnt firing properly, so at about 45 mph she would really start shakin so i just drove around with it in a lower gear. might wanna check plugs,wires, power pack, and air filter, maybe even spray out throttle body.. if u have a schrader valve check fuel pressure while at it. could be exhaust related too if the cat is clogged.  just some ideas

To start off, install a K&N air filter,or something of the same type. Next, put in a real good set of plugs{spark}like split fire,LGSpremium,Bosch.... Then ask around at the local parts place and see if they make a better chip for the Cav. I'm into V-Dubs so I don't know for sure if they do.Next make the exhaust as free flowing as you can and still be legal.  More air in, better burn, more air out makes any motor better.Most of this can be done fairly cheap too.  Have fun.

Well you can find out by un plugging the connecters one by one till you find the bad one (you have to plug them back in too. The bad coil will not change the running of the engine or go to autozone.com

try some octane booster it will clean your fuel injectors and give it some go

Losing the a/c pump will not gain horsepower if you don,t (it free Wheels when off)turn it on, a/c will draw up to a small % loss even when on\nyou will not notice it, only when you first turn it on the other thing i am thinking about here is you cant guess this stuff over a coumputer, need to see what realy broke !, a smog pump will draw less then 1/4 horse power, a dino will not even pick the up, besides the air pump is there for a reason, it cool combustion temp and ehx temps its a freind to your motor, dont belive otherwise. send photo of damage i will tell you what to do next, p/s that car is plenty fast from the factory, speed kills so keep it stock

O2 sensor. same thing happen to my sons Saturn
