Rb20 Bounces @ 2500 Revs

[Duff_man]

hello, i have a r32 gtst with a problem that is driving me insane

lately it has been bouncing of 2500 revs and wont go any higher, as well when this happens it idols really high

when i drive the car in the morning it is fine but once the car seems to heat up, it idols shit and does the same thing. this also occurs if i drive the car then turn it off and leave for around minimum of 15 min and then i start it up again

sometimes if i drive it at a constant speed it seems to go away

i just got a NEW air flow meter, TPS and oxygen sensor, and got dyno'd. All this work was performed by Dynomotive in bayswater, Vic

it was fine when i drove it away and for about 30 min but then i turned the car off and waited around 15 min, then started it back up, it did the same thing for a few k's then stopped doin it

i have noticed a black wire on the air flow meter wiring harness is a bit stripped, would this contribute to it?

any reason why it does it when its hot?

PLEASE HELP !!!!!!!

check the afm plug and wiring, sounds like its in limp mode (afm disconnected)

yeah thanks guys i will take that advice on board.

i just find it abit wierd that it really only happens when hot, im not sure whether its related or just co-insidence

+1 AFM... i think you have your answer. It definitely sounds like its going into limp home mode, so i would re-run that wire that you said is exposed.. perhaps its shorting on something.
