for some reason my mileage suddenly dropped drastically, like from 420 miles per tank to like 320 miles with no different driving on my side. I felt this at first just a little before I hydrolocked the engine. After I got the car running again I could see well that mileage suffered, but I can't say for sure the hydrolock was the cause because I felt it before it also. I think it also used to pull better (well, as much as a stock 420a can pull anyway). Idle is ok when warmed, kinda rough when cold.

Any ideas what I should be checking, cause I'm afraid I'll just start throwing new parts at it at random.

Tonight I'll do a compression check.

only reason things would get that bad would be from a lower VE, a cylinder or cylinders that arnt sealing or putting out the power they use to. This can be from anything.

just did the check

last time I did it was january and back then it was 205-210-205-210, 1-2psi error margin (don't remember exact numbers)


now it's like 193-183-182-183

no huge difference between cylinders, but lower than before...

Measured consumption at 22mpg today. That's ridiculous. Any suggestions??

Change your o2 sensor? My car did this once too after getting in some deep water (not hydrolocked, but I guess it splashed on the sensor). I got 19 mpg and it ran like complete shit.

the front one is the one that the ecu uses the most. Thought there are theories and to a shorter extent some reported cases of the rear one affecting the ecu.
