New to this site. I have a 1999 SE Limited Edition that has a P1230 code. I am assuming one of my ignition coils is bad (seems to be almost common for Max's) and am looking for info on how to diagnose which one (or more) so I don't have to buy all 6. No other codes are coming up at this point. I don't want to put much money into the car because I am selling it in about a month. We have new inspection requirements in upstate NY which wont let a car pass without all CEL's fixed and I want this car right before I put it on the market. Any help will be appreciated. Thanks.
