Having Trubble Reving Past 5000 Rpm Under Load

[Alexis85]

so i have this new problem thats was intermitten but now seems consistant anywas its having truble reving past 5000 rpm under load (like 3rd and 4th) and it sometimes has a small back fire, and pop but other then that it seems to be running fine... any ideas?

thanks

there will be many people on here that can solve this problem however jsut to get the ball rolling, possibly your AFM (air flow metre) folwing and therefore the ecu is 'retarding' the way it drives. also possibly your spark plugs are old or coils are not up to sctach, that would probably explain the missfire, here is just some ideas...get the plugs changed over, check the terminals on the AFM and make sure coils are all working fine.

could be boost leak

since it is an R32 and not R33, it is not rich and retart.

your problem will most likely bee spark plug or coil pack related.

easy fix.

6 new spark plugs - $24

Roll of good quality Electrical tape - $5

Gap the spark plugs to 0.8mm and put them in (search this forum for the part number of the spark plugs to use)

tape up the coil packs which are already out to get to the spark plugs (search this forum for detailed instructions)

done.

2 hours and $30

(it may take you less time)

if it only happens under load, then you could only really check them on a dyno.

Just tape them up as per instructions in many other threads..

Here is one I bothered to type it all up in
