My 2000 Grand Caravan check engine light has came on. It feels like its got a misfire i believe, but not for sure. I just replaced all my plugs and wires. I checked the codes myself and all i'm getting is "55" which from what i understand that means the check is done. I have unplugged the battery cable and then drove it and the light came back on. I then retried the code check and got the same results. Anyone had this problem?

 

Welcome to DF
Are you using a scanner to read the codes? Because the code 55 was on the early dodge products. 1982 to 1995.
