I don't have an answer, but do have a similar problem, with my 1998 GC 3L. In my case, the pending codes seem to be a Cyl 2, Cyl3 and Mutli Random misfire. However, final code is usually Cyl 2 misfire. Mine always happens at 6mph and when the van is slowing down. I have tried the basis, compression, plugs, wires, distributor cap and rotor button. Also replaced #2 injector. No change. We do not feel any missing. Van runs very smooth. I am beginning to think it is a computer/sensor problem. It is very strange to me that it ALWAYS happens at 6mph and slowing down. This is based on the frozen data.
Check the air filter.
Yes they can, if one or more are either stuck open or not working at all it will cause a misfire.
P0300 = random misfire. Could be as simple as needing a tune up.
It can cause it to only have second and reverse gears.
Theres three coil packs; one fires two cylinders. I suppose if one is bad then it could cause the two corresponding to misfire. I had one cylinder misfire, it turned out to be the fuel injector.
I've had a problem with my O2 sensor and air filter causing my 1998 firebird to misfire.
Christmas Caravan was created on 1998-10-06.
Bad coil, wire, plug. Fouled plug, vacuum leak.
P0030 - HO2S heater control circuit (bank 1 , sensor 1) P0300 - Random/ multiple cylinder misfire detetected
This could be bad spark plugs or plug wires
No the gage has no effect on firing. An engine that is overheating will misfire.
I had the same thing on my 2002 caravan sport and I changed the caliper, rotor, and pads and no more clicking.
There isn't a vacuum line going to the regulator on a 1998 Dodge Caravan.
No, the vans are completely different shapes and sizes.
Yes, they are same size from '96 to 2002.
A 1998 Caravan was never built with a cabin filter.
High idle, misfire, check engine light,High idle, misfire, check engine light,
Apparently, according to a Dodge retailer, the computer on the 1998 Caravan can't get reprogrammed (the EPROM is not flashable). A new one is necessary...
I have a 3.8 Caravan and get about 15 miles per gallon.
Failed fan motor, relay, wiring, fuse, computer.
