This may not be the right forum so move if needed but I figured this one gets the most traffic.

So I bought a 02 cavie with a blown eco.

I took a eco out of a 03-05 (not sure the exact year) and replaced the blown one with this motor. Now there was a little discrepancy about using the 02 injectors and rail. The guys that were there when I swapped the engine say that they have ready that I have to use the 02 injector setup with the 02 computer since the 02 ans 03 injector impedence is different.

Now after a couple days of driving ive found the following:

Pulled my codes and had a intermittant P0172 code and the odd time off acceleration like at a stop light itll bog and the rpms will fall down to like 500 rpm and try to die.

Any ideas? Help would be greatly appreciated
