2006 Ford Ranger: check engine light

Filed Nov 6, 2018 · Engine · 130,000 miles · OK

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. Needless to say I had drivers behind me honking and flashing lights but the truck just wouldn't go over about 5 MPH until I was down the road a bit. The first time it happened in april of 2018 and it has intermittently done it several times since then with the latest time being yesterday 11/5/18. I have done some research and found out that there are known issues with the heads on this ford ranger. I have contacted them about the issue and seemed to have not gotten anywhere with it.

Consumer writes in regards to vehicle defective cylinder heads. *smd the consumer stated according to fords technical service bulletin 05-26-3 the engines were built at the factory with defective heads. If the check engine light illuminated, the heads needed to be replaced, as it was explained to him by a mechanic at a ford dealership. The consumer stated it appeared to be defective materials in the heads, which required the heads to be removed and scrapped, along with the head gaskets. The heads appeared to be made of soft iron, where the base metal was perhaps not heat treated.

Vehicle stalled in middle of an intersection at 46,00 miles and was found to have lean codes p0171 and p0174-they replaced the intertia switch. Vehicle went in for service and a po306 cylinder misfire, but paperwork stated could not duplicate. After repair, vehicle kept giving me the check engine light if I filled the tank up with gas, but would clear itself before I would get to the dealer. One day I am makeing a left hand turn and the check engine light had come on about 5 minutes before. The ford ranger sputters across the intersection and then speed up very fast. Ii was lucky not to get smashed,as the light changed while my vehicle was sputtering. I immediatly took my truck to my trusted auto technician (not a ford dealership)who told me I had po codes po304 and po316.the tech provided me with tsb number: 05-26-3 date of issue 12/31/05-(they knew my vehicle would fail before I purchased it!) the tsb states 3.0l-2v vulcan engine. Mil on various misfire related dtc's p0300 - po306 and p0316 issue 12/31/05 my 2006 ranger with 69,000 mi displays all for the issues indicated on this tsb. This malfunction causes the mil lamp to continually display trouble codes p0302 and p0316. Because of this, my vehicle will not pass the ca state emissions inspection. The tsb states that if diagnostic tests indicate an engine exhaust valve seat recession, the cylinder heads will need to be replaced with the new service heads and is to be covered under emission warranty. I took the vehicle to the ford dealership. Pacfic ford redid the diagnosis and stated the issue was outlined in the tsb. They also stated that the parts were not covered by either the new vehicle or emissions warranty coverage. I called the ford crc and was told there was nothing they could do to assist with payment to correct their defective part. The failure is not being corrected at this time.
