cleaning diesel injectors
Anybody have real prroof that any of these off the shelf diesel injector cleaners actually work ?
my car 16v mjet smokes like a bad un, alwasy has, i was told that the injectors are leaking, or not closing properly, or leaking back or summat like that, so ive tried all manner of cleaners, with full tank, virtually empty tank of fuel... never seams to really improve things
ive also tried cleaning the map (cannot see how a pressure sensor would be affected by soot however) cleaned the egr and the MAF, reset the ecu and changed the stat, although its never ran above 70 - so it could be faulty again i guess
anyway, injection cleaners anyone ?
or what about a gallon of petrol in a full tank of fuel ?
