Very hard to say could be alot of things,

Like any power loss problem check boost and fuel and timing.

Maybe the intercooler piping is leaking somewhere?

Is the fuel fresh in the tank? It does go off after a while.

It should not need a retune they dont just fall out of tune sitting there.

good luck

i put it on the dyno today show the engine was running on 5 cylinder and was pretty lean, that explain the approx 80hp power lose.

they told me first replace spark plug to fix the mis.

If this does not fix the problem it either fuel pump or injector block or fuel rail.

well i hope it just the sparkies

anyone know what spark plug to recommend on r32gtr?

pls post ur recommendation

thx all

not being started in a while can cause rings to cease up on the bore. creating gouges or scratches in the bore. can be bad i guess..

a thread i readed b4, sumone had the same problem,engine feel restricted,shyt of shake when accelerated, it was sign of misfire eg.coil pack or sparkies.

The thing i wanna know is a guy post these commend below

is it safe to do what he stated?

"to find out which cylinder it is, unplug the coil pack while the car is on... If ur idle drops then that cylinder is fine... If there is no change in idle u know u found the problem one."

yeah exactly how you should do it.

or use a consult cable and turn them off 1 by 1 via the software.

other missfire reasons could be dirty afms, cracked coil packs or ignitor dying. you really just need to swap things 1 by 1

i mainly concerned about the mis or spark problem that causing the engine to run on 5 cyclinder or 1 of the cyclinder just damage due to car havent been driven in 6 month.

so do u guy think is the mis that cause engine to run on 5 cyclinder, coz engine was in great condition b4 crash nothing was wrong, crashed neva affected engine so why is it after fixing the problem like these arised.

[Godzil_R]

btw does the miss cause lean,mine was pretty lean on the dyno graph

showing sumthing like 14:1 afr

were did the engine sit after the crash and how bad was the crash was it still driveable?

crash neva touch the engine i only fix from front to radiator that it

after crashes it set their 6months while i was chasing parts, wasn't drivable cos intercooler n radiator was wrecked

The crash probably isnt ur problem. Sitting your car there for 6 monts would be.

Like you said, remove all coil pack 1 by one to find the cylinder thats missing.
