Hi carman850
what kind of fuel consumption figures do you get on your 400E.
I get about 17-18mpg city (Lots of uphill and downhill driving) and around 26mpg highway on mine.

changing the injectors along with the fuel pressure regulator sounds like a good idea to me. They are about $25 a piece and easy to replace. You might also want to have the fuel distributor checked. If compression was good 1 year ago there is most likely no reason tho have one done now unless you can the car low on oil or something like that.
Engine temperature seems about right.
Any problems with the idle? rough? intermittent shaking at a traffic light?If you had the cat cut out you might be looking at a backpressure problem.
Best of luck and keep it up!
