flow bench tester? theres a shop here that cleans fuel injectors, perhaps they have one of those?
I used the stock BKR5E spark plug as specified in the user manual.
ill get back to you on the compression
as for the fuel pressure... the fuel pump im using isnt really for the sentra, but that wont affect fuel pressure right?
[Intake system vacuum leak] smoke tested and no leaks.
PCV fits snug to the valve cover and hose is clamped down properly...
Ill take it to the fuel injector cleaner once i got the engine mounts all sorted out...
Just a quick update:
After doing some tests, I found out that injector number 2 sometimes leaks and is sometimes stuck closed (causing the engine to run on 3 cylinders). But usually it just leaks.
Started the test with a fuel pressure gauge connected where the fuel filter should be, ignition on engine off... at first pressure would stay steady at 30 psi but after numerous ignition on/off cycles and engine on/off cycles I was able to simulate the problem twice...
I replaced injector number 2 but still seems to be running rich, so I brought the car to the mechanic and told me that the car was misfiring at idle and the injectors are clogged, I believe that clogged injectors would cause the car to run lean not rich...
I was told to put some fuel injector cleaner in the tank, in hopes of solving the problem I put a bottle of techron in the car... im currently hoping that it would work.
oh and rogoman, I did a vacuum test, the vacuum at idle shows 19 inches of mercury but sometimes fluctuates (goes down to about 16 then back to 19)
