I'm Awesome
So I'm thinking about going on a road trip, cross-country, and I had this thought about wiring a couple switches. One grounds out Injectors 1, 4, 6, and 7. The other grounds out 8, 3, 5, and 2. (Firing order is 18436572). The goal is to increase my gas mileage on the highway. By having 2, I can switch between them to ensure more even wear.
The thought came about since my #3 injector has been consistently misfiring and I've increased my MPG from 11.5 to 12.7 average, and 16+ Highway (from 13.5) without any noticeable loss of highway performance (takeoff is a bit slower though.) I was also considering GMs Displacement on Demand for exactly this purpose. But an actual DoD setup rotates through the cylinders to more accurately wear evenly and it (of course) enables and disables itself automatically.
So besides my computer throwing codes for constant misfires, can anyone see any reason not to do this for those many hours cruising at highway speeds?
It's a 96 Vortex 7400 (454). Just my truck, kids and luggage. Not towing. Nothing on the rack. Constructive responses appreciated. Thanks.
