I have a 2006 3.7l Jeep Liberty. At the current time it has a starting and running problem. It turns over but only starts after several attempts and then quickly stalls out. It has a delay in acceleration, when I am able to get it go without immediately stalling out. I have changed the fuel pump, fuel filter, map sensor, crankshaft sensor, camshaft sensor, throttle position sensor, cleaned the throttle body, changed the plugs, changed the fuel injector O-rings, all to no avail.
I am now thinking it may be the Catalytic converters. Any suggestions? Thanks in advance
