[QUOTE="JimNH, post: 435659, member: 18470"] not getting very far. going to have to bite the bullet and start disassembling the top of the engine to check out the injectors. I dropped one of the old spark plugs while changing no. 3 and now I can't find it...think it's trapped between heat shield and manifold. Can't win. I cleared the codes and am now getting the P0300, not the P0202 - weird. I am starting to think it's the wiring harness to the injectors- the insulating sleeve around the wires got brittle and fell apart, and I need to get a look at the wires further back than I can see from the throttle body sensor area. What is really stopping me is having to take off the EGR pipe - PITA. [/QUOTE]
