Chrysler 300m engine knocking after replacing plugs and wires??

I am looking at buying a 1999 Chrysler 300m the car is in immaculate shape but...the lady that owns it now says that she took it to midas because it was running a little rough. They changed the plugs and wires but they told her that engine still has a small "knocking sound to it". She wants $1900 for it...It has 100,000 miles. My question is could the cylinder still not be firing making the engine knock sound? Could it possibly be a coil pack? Is it worth buying it at that price even if I have to replace the motor in a couple of months?

Absolutely NOT, to many unknown miles, if you are dead set on it, at least take it somewhere and have a compression test done and do this in person! you can buy that car all day long at dealer auctions from 400 to 800 dollars, a new, or used engine and the labor will be in the four figures, using professional people, the old saying is, if it sounds to good to be true then it most likely is! take your time and at this time in or world i know you will find something that will give you much more and better service, hope we helped, and good luck to u..

1999 300M the engine is knocking. It also shuts off in mid drive

There is a Knock Sensor (1) on this engine, but is in the center of the engine UNDER the intake manifold on the block (in the valley, the valley so low). Check the values of the voltage in a Chiltons or OEM book and unplug it from the rear and test it before you remove it. (Quite a job removing the plenum, wires, Manifold and finally the knock sensor (about 75 bucks in the Midwest at a parts store). If so, you are lucky in a 3.3L you have to remove a HEAD.

Very good chance the exspansion plug (freeze plug) at the rear of the engine has rusted through. Not maintaining the correct antifeeze solution may have allowed rust or electrolisis to occurr.

The car cranks but won't start

Ok, check the following below--

1. Check the Ignition control Module for its operational value. it may be damaged.

2. Check the coils.
3. Check the plugs and wires.
4. Check the ECM/PCM/ECU(All represent the same device that is commonly known as the engine control computer)

Check these areas thoroughly for faults. I would also advise to replace the fuel filter and fuel pump as well.
