NEVER NEVER NEVER EVER! let anyone tamper with a bosch k jettronic mechanical fuel injection system if it is working!! If the car is acting funny chances are its something else.Mechanical fuel injection is very reliable nothing else on the car is. Check everything else before touching the mechanical injection system.There are practically no mechanics who know how to service these fuel systems.Anyone else who claims he can adjust or "tweak" it I advise you knock them out with a billy club and drag them a safe distance from your vehicle.Start collecting literature and service manuals on bosch systems thats your only hope now.Four months of sitting shouldnt have been that hard on it are you sure it wasnt longer?I am sure there will be plenty of rebuttals to this post but these are the same people who also posted previously "Tune up gone bad". So how much credibility can we really lend them? --------------------------------- Do you Yahoo!? The New Yahoo!
