Should it be a given, that regardless of milage or driving conditions, etc. that after 21 years its safe to say that the fuel injectors are in need or cleaning or replacment. Delorean.com sells the injectors for about 30$ a pop well, it says injector nozzle and there are six of them... i believe the are them. delo # 102742 Im not trying to suggect any bad maintenance practices here, think of this as a hypothetical question. It seems all of the negative comments that was raised about bottles injector cleaner was mostly about the sludge and varnish clogging the injector. and some had concerns about the injector seals. Would it be good idea / bad idea in a scenario, to burn down a few tanks of gas with injector cleaner, if indeed you had every intention of removing the injectors for cleaning and / or replacment anyway. I imagine removing a 21 year old injector along with its seal , would pretty much mean you would have to have new injector seals on standby regardless. so barring the injectors and their seals. would fuel injector cleaner still present a problem, as a means to clean through the fuel system as opposed to replacing it. thanx jordan 11613
