Description of the problem | Re: 2001 ford svt lightning my vehicle violently ejected a spark plug from the engine's head, while merging on a highway on-ramp. Upon failure, the vehicle obviously started misfiring, bucking, and was a handful when pulling over to side of the road. Ford only used 4 sets of threads on their lightining heads from 1999 to early 2003. Conventional heads typically use between 8 and 10 threads to hold a plug, but ford designed their heads with only 4 threads on many modular 5. 4-liter v8 motors too (not just the lightning). They have acknowledged that there is a problem, as they have changed the head design in early 2003 to a new part with 8 threads. But ford has not issued a recall for older lightnings (and other f-150's), even though this could be a potential safety problem (fire, loss of control, etc.). I have already had my head replaced with another inferior 4-thread design, and i wonder when the next plug will be blown from my engine. I would like to see nhtsa encourage ford to retrofit all affected vehicles as this is a common problem for many lightning owners. |
