Hi, not an auto guru, but a 100 yrs ago (or feels like it), I could easily do a simple spark plug change. Now, this car is ugly under hood, everything in inaccessible locations, and sadly, your 'info' is fairly useless. Before I trialed JA, I knew Meaning of the 2 codes, I've got ONLY the #2 cyl plug, and attached Ignition coil off, s/ able to buy & replace. The pic for the APS looks NOTHING like what's under my hood. For clarity, It is a 2003 HYUNDAI SANTA FE v6 3.5L. There is a wire 'roller' (dunno proper term), with what looks like a sensor on it, that 'rolls' when accelerator is depressed. ASSUMING that is it, but is (to me), unreachable. Air filter
assembly is above, and if removed, is still at unreachable location. Im looking for a real answer, already did web research, now, stuck. This service is so far unusable. If you have usable info, on how to get to the APS, I'd appreciate a reply.
