Please Help... *sighs* Again.

I thought i had solved my random "engine/power cut" problem, but now something similar has just surfaced...

To fix my problem above i had every sensor tested AFMs Reconditioned and an stk ECU installed (to replace mines ECU).

The problem was the ECU.

for the last 3 weeks its happened 3 times and gotten worse every time.

last time i was cruising, in 3rd or 4th (2-3000rpm). I hear like a "clunk" noise? From underneth

then my Revs go from 3000rpm to almost 0 then back up then down up down up down. while this is going on, me reving has little

if not no affect on the cars Hunting??? up and down until eventually i stalls.

i start the car again and will hunt for a bit then die, or idle incredibly low @ 1000rpm (normal idle is 1400rpm)

after 10 minutes the car is fine...

in the last 3 weeks if had a while alignment, a new clutch installed and a Greddy Boost Controller installed and tuned (low 12 high 15)

ok.. so tested the sensor. How about the fuel pump and fuel reg? Or even the fuel filter.

yeh they were the first things i did.

recently put a R34 gtr fuel pump in there.

Boost leak??? Where does the 'clunk' noise come from??

[joeleo87]

if it was a boost leak then i rekon the problem would be more consistant?

under the car, in the middle somewhere maybe? although i think its linked with the sudden drop in revs and it might be jolting the shaft from the transfer case to the diff?
