Re: [Chrysler300] 62 Sport problem

Doug,

While I was trouble shooting my miserable running problems, II bought stranded wire and ends from NAPA and made a set of plug after buying several sets.

The plugs specified in the shop manual (J12Y?) were avaliable on EBay fromNOS and I bought a bunch of those . They were were cheaper than new plugs.I also bough sets of US made, Bluepoint or Mopar ignition points from Ebsy. I did not use any old condensers though.

I did no have your problem. My major problm was an intake man ifold leak I found only because this group suggested it.My engine finally ran smoothly and relaibly after I had a top rated shop taake it in and spend some time. By the time it went to them. it had "restored" AFBs. new damper, rebuild dstributoor, new intake manifold gaskets, dwell spot on, plug gap spot on and carbs adjusted per shop manual. I do not know what the mechanic id. When I ask, he just smiles and says "I have been doing this I was 12, and I love it".

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
