    I'll be honest and say I dislike Gavin's avatar. First of all, I hate crown vics, they remind me of the po-po. Secondly, every time I see it, I watch it over and over again and loose track of what I was even doing in the first place. banghead.gif

  19. Amber Lights...

    You want to put a 3157, instead of a 3157na in the socket? It'll work, but it'll be illegal, but what isn't. Just get some amber led 3157 for the socket, it'll be clear when off and amber when on? Of course, with leds you will have to put a resistor in parallel for it to flash properly.

    The size of spark plug gap was dependent on the type of plug used. When Chevy used platinum, they gapped them at .060. When they switched to iridium, they gapped them at .040 for smoother idle reasons. There is a TSB on it if you search. FWIW, I sidegap mine at .055. Matter of fact, here it is.

    A new spark plug has been released for use in the above vehicles. The new spark plug has an Iridium tip instead of the current Platinum tip. Due to the different tip design, the gap of the spark plug has also changed. The new spark plug, P/N 12571164 with AC Delco P/N 41-985, is gapped to 1.01mm (0.040 inches) when the spark plug is made. The spark plug gap is set during manufacturing and should not be changed or damage to the spark plug may result. Any new spark plug found to not be properly gapped should not be used.

     

     

     

    GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
