Not leaking down the spark plug tubes... and plugs look good. Interesting... that high tension lead for cylinder 3 reads open circuit... but when I McGiver'd my '99 Camry sparkplug lead in its place (and the Camry one reads about 12,000 ohms) - no change in behaviour was registered. I guess even if the original plug lead read "open cct" it would still fire when high voltage was applied to it. Re oil burning... it DOES burn some oil. The plug on cylinder 3 looks a bit oily... rest do NOT. But the codes point to cylinders 1 and 4... not 3. I would not consider the plug lead on cyl 3 to really be problematic. ? I will check out the Harbor Freight (and possibly Princes Auto) fuel pressure gauge. The car has no fuel pressure element that I can see.... Is there typically a transducer that "talks" to the PCM in regards to fuel pressure? Is there some feedback to the PCM that a given duration of injector pulse equals a known amount of fuel (assuming that the injectors are not clogged) - by saying: "I have pressure; I have duration of pulse, therefore I have such and such amount of fuel properly injected"?

I assume you've pulled your plug boots and looked down the valve cover to make sure it isn't leaking oil in the spark plug tubes. How much oil are you burning? I had a worn out corolla with that motor that would stall after I drove it on the highway and shut it off for gas. 2nd restart always worked. I think it was fouling its own plugs. Harbor Freight (Princess Auto?) sells a fuel pressure gauge that splices inline with the one in your car, doesn't need a tap.
