Re: [Chrysler300] 62 Sport problem

Great when stuff we all share helps. And as simple as that is to repair. Those capacitors are everywhere , rubber cone on wire  end  and indented stamp lines in other need . Junk . Before finding this drove me crazy . And remember it is intermittent .. work one day , not the next . Keep old mopar with copper strap . No need to change it in general . Can be tested . On high ohms Analog meter , set on megohms needle should jump up for a half second and fall back to 2 megohms or more . Open cap does nothing , shorted reads low ohms. Very rare it is defective . Digital meters useless for this. 

Happy  it is running well ,

Bad capacitor , the ones with rubber cone around wire in many “ new capacitor” box are junk . They do intermittent ,= weak spark . Best are old mopar with the flat copper strap . Do not throw those out unless positive they are no good. Which rarely happens   . All the same ,  6 or 12 does not matter . EE hat on . Be a sure the coil tower is spotless . Can arc over to two terminals there .

Hi Group,

I need some expert input on my 62 sport conv misfiring or "stumbling". The car has the standard 413 and I have added the dual AFB's and a dual point distributor.

One year ago driving to and from the Ironstone Concours in Murphys, CA ( about 80 miles away) I experienced severe  misfiring.

Pulled all the plugs and found #2, #6 & #7 fouled with carbon deposits ( #2 by far the worst).

Replaced the plugs and thought the problem was solved. This year, drove to local shows and around my neighborhood with no problems.

The trip to the Ironstone Concours this year resulted in the same misfiring  problem.

Pulled all the plugs and only #2 had any carbon deposits.

Checked the compression and all cylinders at 150 +/-..

Checked and set point gaps, replaced the wire to #2 plug.

The engine runs ok with no load, but still misfires or "stumbles under load and at high speed.

The new plugs that I installed last year are Autolite A42B's which I believe are correct. However they may be 30years old or older. The cap and rotor are only a year or two old.

Could a defective coil cause the problem?

Thanks,

Doug Warrener
