Bad Idle On R33gtst

[seanisonfire]

hey guys..

the idle on my r33 has been a bit bad today.. going up and down btwn 500-700rpm

it has almost been wanting to stall!! it stalled once actually but i dont know if that was the engine or driver error.. (i was in 2nd and may have been going a lil too slow)

i have only recently purchased it so i dont know if it needs a tune to fix it or if it might be somehing more serious!?

AAC valve... search DIY...

also change oil, change spark plugs, clean AFM..... also 500 is alittle low for idle... should be 650-750ish..... i had that problem when revs were at 2k and then droped it to neutral, sometimes it would stall....... i did what i said and cleaned aac valve and stopped stallinng prob.... although i can see my car idle still plays around a little... but doesnt stall anymore

well as i said above, i still had some idle play after doing this, but changed my 02 sensor and idle is dead constant now, no play at all, and better fuel economy.....

hope this helps

I recently purchased my o2 sensor.. but im having a bit of trouble getting the old one off..

Did u guys take out the heat shield etc to get to it? Or have u guys got some kind of trick to get to it?

seanisonfire: like axe s & Kujotk said these things may fix it and even if it doesnt, it sure wont hurt

br3ndan:

1. remove the engine heat shield

2. remove the three bolts holding the brace, then remove it

3. undo the screws holding on the heat cover over the dump pipe and remove it

4. replace the o2 sensor either with a 22mm open ended spanner or you can get a oxygen sensor socket from Repco (when i asked they said they would have to order it from over east so I just used the open ender)

5.then reverse steps 3-1

i didnt bother unbolting the old one because it looked like a bitch to undo and id probably thread it anyway..... i just cut the wires and took off the hole dump/front pipe and replaced it with a 3inch version and a highflow cat....
