If I pull the PCs line it will idle way upI have not checked injectorsWhat is best way to do so? With low miles and I use injectors cleaner at every oil changeAbout 1500 miles ago I used BG fuel cleaner, engine flush and moaUse synthetic oil and change every 5,000 milesIn my diesel trucks have had good luck doing so
