Replaced passenger side fuel injectors with rebuilt ones from Auto Value. Also reseated the drivers side ones that I installed a few days ago because of a small leak after I put them in. Been trying to get to the bottom of a P0300, P0302, P0305 problem. Replaced plug wires. Same. Replaced spark plugs. Same. Swapped coils. Same. Replacing the fuel filter tonight. Been soaking the fittings for the last few days. Also replacing my plenum gaskets today because the old rubber coated metal ones were looking pretty ratty. Oh the Toyota dealer checked compression, crank and cam sensors before and they are all good. If these injectors and gaskets don't do it I'm swapping the MAF and igniter with a couple of used ones I just got. After that I'll be looking at new coils... the primaries measured 1.1 - 1.2 ohms cold and apparently that's borderline. Not sure how accurate that is because both of my Fluke meters read 0.2 - 0.3 just on the leads... Fun!
