We had a problem with the car sputtering and acting like it had water in the tank. we took it to the shop (not the dealer cause they are the worst people in the world, at ours) and they ran test for 4-5 hours and told us that on top of needing a new converter, we needed a new PCM. so we ordered one and were going to have our friend put it in for us. then my husband decided to drill holes in the converter to replace at a later date. the car spit out a lot of clogged pieces but is currently running find without replacing the $700 PCM.
