Help Me Find A Solution To My Cars Problem

[r32na]

hey guys i was wondering if any one can solve this...

My cars been misfiring abit and it got to the stage where when i gave it up... it wouldn't rev over 5g it just bounces back and sounded like something was holding it back, and also sounded gross... i changed the spark plugs and coilpacks, and its still doing it.

It also misfires and backfires around 2g when im in a high gear at low revs... then when i was testing it last night showing a mechanic mate of mine it still wouldn't go over 4-5g it just shat itself and wouldn't let me rev high....

Is this my timing from the computer? does it need a tune up or is there something else im not aware of.

cheers

also does anyone know the if the waterpump in the r33 rb25 is the same as the pump from a rb25 in a r32?

sounds like airflow sensor see if you can borrow one to test

I had a similar problem. I thought it was the AFM. I bought a new AFM and it didnt f**king arrive like they said it would yet, so I changed the fuel filter (which was filled with dirt and f**ked up shit) and it seems to be running perfect now.

Same broblem years ago. Air flow meter. Try the wreckers to see if they will let you try one

Sounds like an afm to me too.
