My 2012 Grand Caravan has an issue that has me stumped. It has 212k miles. This may be kind of long but I will try to shorten it. About 2 months ago the van developed a really bad miss. It was compression tested and turns out it the left cylinder head was bad- had a dead cylinder. Well the cylinder head was replaced and all felt good until now. The last few weeks, while driving, the van will just randomly miss 1-2 times and when it does, it is a hard hit. Almost feels like a torque converter trying to go into lock up. At first I thought it may be the torque converter but today, I watched the misfire counter on my scan tool and noticed every time it would do it, either cylinder 1 or 2 would misfire. It is very random also. Nothing I do while driving can manipulate it to act up and it just does it whenever- sometimes cruising and sometimes when lightly accelerating. Any ideas?
