Engine runs ok sometimes, other times dies after put in gear, or it may die when driving and may or may not restart.
Ford Ranger XLT, automatic, Dual Plug ignition system, 4 cylinder, 2.3, fuel injection. vin#1FTCR10A3LUA73667, Truck will start and run fine , sometimes, other times it will start and engine will stop running when placed in gear, other times after driving a short distance trucks engine will stop running and may or may not restart. 68,000 miles on truck, new fuel filter, new plugs and wires, timing has been checked. I believe it may be an electrical problem but not really sure where to start looking. any ideas would be helpful. Thanks, Rick
Try using a timing light or something to see if all the wires are firing. I have seen customers change all those same parts and find out one of the coils were bad. Really that was a weird design as one of the two plugs on a single cylinder fires on the compression stroke and the other fires a few milliseconds later to scavenge the rest of the unburned fuel in the cylinder. That really never went very far, Nissan also had that same engine and I think it was only in production 2 or 3 years.
