Depending on how many cigarettes you are smoking every day, you may have either a small or large amount of nicotine in your system. As a guide, nicotine usually lasts between 2 to 14 days in the urine, 2 to 15 days in the blood, 1 to 4 days in the saliva, and between 30 to 90+ days from last use of nicotine products.
Coil resistance? My book says my coil resistance should be 4.0 Ohms (+/- 10%) on the primary and 9.5K on the secondary (+/- 20%). Unfortunately, I get 2.9 and 2.7 Ohms (more than 25% off) and 20K to 18K (like 100% off). Any time I use the electric starter on a cold, choked engine, my plugs like to foul.
Ignition coils transform low voltage electrical power 12 volts D.C. to high voltage current 50,000 volts D.C. or higher. The spark generated by the ignition coil ignites the fuel and air mixture in the engine that enables the car to start and run smoothly.
