Hello all my name is Rob, in need of some assistance here. Found some of the other posts very helpful, good site! My car has recently started to idle rough, surge, and almost feels like its going to cut out. Last week I had it in the shop for this, an hour after it was dropped off I received a call stating my car took a dump. The ICM was shot and not functioning. I was suspect at first about the repair shop as I only started using them recently, they are telling me that my car is dead and the part is $3600. I did research unearthing the fact that the ICM does indeed fail, so I started the search for a donor. I was lucky to find a second hand module that worked, figured my issue was solved and it seemed better off at first until it all started again. From what I have been reading some users say its essential to replace the coil, cap, rotor...I am willing to do whatever is necessary! I am almost positive this is an ignition related issue. At the same time do not want to throw unnecessary parts at it. Taking it to a recommended 124 specialist soon but was interested to get some feedback here too. My car just rolled over 60k, always maintained! Feel nervous driving on this new module when it sounds like this problem is corrupting it and could potentially leave one stranded, need to get it fixed asap.
