Well, this is a continuation of the post from yesterday, it wasn't
a fuse problem or loss of power to ECU at all.
It has the B230 (or 2330?) 4-cylinder FI engine, BTW.
To describe a little better what the car is doing, it seems to be
getting around 2 miles to the gallon. Even before the acelleration
problem developed, it had started to eat gas. it will run fine when
in park or neutral,has normal acceleration. When you drive the car, it
will take off with normal pwer from a stop, but right after it shifts
into third, the engine just shuts itself down to idle speed, even
though you continue pressing the gas pedal. You kind of get thrown
forward in teh seat! To get going again, you have to let off the gas
completely, then you have control of the engine speed again.
I was told it was a bad AMM sensor. However, it doesn't look like
that is the problem. HOwever, like I said, the check engine light is
NOT on...and when I read the codes for both 2 and 6 (its the Bosch
LH2.4 system) I got 1-1-1 on both. No codes are being set, even though
it has this severe drivability problem. To test if the ECU was
picking up faults from the AMM sensor, I disconnected it. Sure
enough I then got a 1-2-1 code. SO the ECU is telling me that the
sensors are good.
I noticed that the big flex duct between the air intake and the
AMM has gotten almost kinked off....I thought Aha! Its getting starved
for air! but when I shortened up the duct and repositioned it so it is
not kinked anymore, I still have same problem. I checked the air
filter, it looks fine.
So what could it be.... fuel pressure? fuel pump? The oil and
tranny fluid are fine.
