I got my methanol injection installed and took the car for a test drive. http://www.alkycontrol.com/ I got it dialed in so i could start cranking up the boost and discovered had an ignition problem( a lot of breaking up and back firing ) boosting any thing over 10lbs. I ordered a new coil thinking that is the problem. When i installed the turbo i replaced the cap, rotor, coil wire, spark plug wires, and spark plugs. What else could the problem be?

plug gap needs to be brought down to about 30mm -35mm.
make sure that your not spraying too much with the methanol injection.
plus, spraying at just 10lbs of boost will net a loss in power when compared to not using it all.[strike:ff0tp92h]1984 300ZXT[/strike:ff0tp92h]

a miss , as in blown out spark, will show up as rich mixture on the wide band. best way to explain is with no fire the fuel is just pumped through, and shows on the wide band are real rich mixture. .040 is wide enough for the spark to be blown out. i run .030 on my nitrous car and both my turbo cars.85 300zx turbo BSP autox
