Hi all. I have a 1996 JGC Laredo I-6 4.0L 4x4. Cylinder #6 seems to die with
no apparent warning and after driving a couple of days decides to come alive
again. When cylinder is dead I get trouble code 43. I had almost replaced
the engine which was gonna cost me $3200 for a new engine from Jeep with 36K
mile/ 36 moths warranty. However, this just boggles me now as the cylinder
seems to work when it wants and goes dead the same way. No warning, no
stalling, just dies and then come alive in a couple of days. What could this
be? TIA.
Fernan

 

Just curious as to why you would drive it for a couple of days with a
dead cylinder, and then continue to repeat the process.

Yeah, not much info here. Have you tested the compression? is it a bad plug
wire? How many miles are on it? Could a valve be sticking? Engines seldom
heal, so hoping it goes away and driving on usually makes things worse.

Why are you driving it around washing the lubricate from your
cylinders with raw gasoline?
