1uzfe still a mystery

[sideshow]

engine running sluggish can be ecu related
alot fo toyota ecus that are around 15 years old these days are starting to play up

unless u want to spend heaps of money guessing
u need to try find a car or engine like yours and try yr ecu and air flow meter in it
otherwise anyhting else u do is pure guess work
diagnosing problems like that on the forums will help a touch but in the end u need to decide if tis mechanical or electrical
then its usually 2 things that will make engine run bad to how yr saying
more than any other part thats the ecu or air flow meter
everything else is very uncommon to fail

read up on all the other bloody posts
theres probably a million guys hehehehe on here that have had problems
and first thing they change are leads plugs and caps and rotors and inj cleaned
i garantee 99% of them it did not fix the problem

so go find some parts to test and see how u go
otherwise find a workshop manual and start measuring voltages
which is very hard to do while road testing under load by yourself

whats the difference?

I pulled the injectors from my 1uzfe (1992 ls400) and i want to install ones from my old engine, the thing is that the ones from my old engine(1992 sc400) are a little different. can i still use them?.

If they are the same part number you can use them.

If they are different part numbers you can't.
