Yes, I saw the coils offered and the reviews agree they arent great. I also see tons of promotion for code reader analyzers for only 150 and reviews say these only read the usual engine codes and that the promotions and claims they will do system analysis of components is false. So for that reason I held off buying an analyser. ($150 seems too cheap) I also found I could reset the maintenance interval warnings from the menu itself, no analyser needed. But hopefully the analyser will help me sort out the issue with the fuel gauge and the window washer pump as well as the air pump stoppage issue. And if i need to replace an air shock or other components, so be it..Thanks for the helpful info!
