My car has 85,000 over the past 6 months it has been sporadically cutting out while I am driving it. I have had it in the garage for a total of 3 weeks and their response is, sorry as it's not running any codes we just can't figure it out you may be best just trading it in...they did change the cat converter and replaced the coil pack and it is still cutting out. I told them that it seems to happen when my gas is low but they said it could cost a lot to fix it as they would have to replace a few different parts to see which one would solve the problem. It happens at slow and fast speeds...any ideas? Thanks a mill
