Asked by Nov 04, 2013 at 10:15 AM about the 1998 Dodge Caravan 4 Dr LE Passenger Van

Question type: Maintenance & Repair

i have a 1998 dodge grand caravan with a 3.3l v6 flex fuel engine. it runs rough at idle
and when trying to rev it. it won't rev past 2500 rpm either. i have tried to check codes
without a scanner using the "on-off" 3 times method as well as the "hold-the-trip-and-
reset" method. the check engine light is on but no codes come up except "code 999"
which i believe is normal. i have changed spark plugs and fuel filter. am i missing
something? maybe it's a bad pcm?

i was able to hook up a scan tool to my van and the only code that comes up is for a bad EGR valve. i can't see this causing my problem though. i was also able to get the engine to stay running for a bit, although it ran rough the whole time. the fuel pressure is at a constant 59-60 psi with the engine running. also, there was no fuel smell when i opened the throttle body with the engine shut off. i am leaning toward a bad PCM with a bad fuel injection circuit. can anyone help?

These engines are notorious for coil pack issues where two or more of the towers short internally. Bad plugs and wires will do the same.
