2006 Ford Ranger Engine Problems

“Sitting at a stop light engine started running rough the check engine light was flashing. I took off and it was not running well and couldn't get speed going until around a 1/4 mile down the road. It has happened several times always at idle speeds, once I get it moving and go up to highway speeds the problem seems to go away but the check engine light stays on. I have had the code read and the likely solution is to replace cylinder head assembly. The code was p0316 which indicates too many misfires after startup and code p0304 which is cylinder number 4 misfire. …”

“Rough idle noticed while stopped at an intersection. Catastrophic misfire upon acceleration through an intersection. Truck was only able to limp 5 or less miles per hour. Check engine light had been turning off and on however diagnostics showed misfire for unknown reasons. Spark plugs and wires had been replaced twice within a year as well. Defected head manufactured by Ford.”

“Ford 4.0 sohc v6 timing chain hydraulic tensioner, timing chain cassette and timing chain failure providing no start situation. Ford is well aware of this problem. It is widespread across models with this engine, rangers, explorers and mustangs. Starting with model year 2001 when they began using the 4.0 sohc until end of production of this engine, 2011 they should be held responsible for low mileage failures. My vehicle has less then 70,000 miles. Timing chain shouldn't fail and dealership should pay for repair. …”
