Jeep Cherokee 4.0L ( 2000) Misfire, runs on Petrol & LPG misfires on both fuels from idle through the rev' band. Drove to work 45miles, and run well after work had the misfire. Fitted new plugs and coil rail, visual check of all hoses and look OK, still running like a bag of nails on both fuels.
Any ideas welcome.
