What is the spark plug gag for a 1979 chevy c10 350?

Have you ever heard of the "mechanics rule" that says if it ain't broke don't fix it? Put the old coil and module back in they're not part of a tuneup because they can last for the life of the vehicle or not lol. I hope this helps. Take Care.

Sounds as if you may have blown a fusible link. These are sections or wire hidden in line with major hot feeds to protect the rest of the harness and usually located near the battery + or near the big feed to the starter. When you say the plug is "pink", do you mean the spark seems weak? Test voltage getting to ignition switch.

A tune up consists of changing distributor cap and rotor, wires and spark plugs. I would check to make sure the wires were replaced properly in the correct sequence and were tightly connected to the spark plugs and distributor cap. Next, if they are are tight, I would make sure wires are not touching anything that could ground them out. Looking at them at night with the lights out sometimes reveals a stray spark grounding out on the engine. Besides making sure you seated the rotor into the cap, I would finally check each plug for the proper gag...they don't come pre-gapped anymore. Hope this helps.

whats the odds of one or booth of your catalytic converters is plugged up?

that can cause u to run than die . if your exhaust dont go out , your motor chocks and coughs , than gags .

Wow, a reply about an Australian based engine. I'm thinking since there is no reply that he just may have a US based engine just posted the wrong size. in which case this might help.
