Need Help

[newboost]

to begin i have a r3 s2 (auto, 103000k on the spedo)

the problem is when it have the car in gear and come to a corner with the brakes on the cars starts to run rough (close to stalling). I have taken it to a couple of the local mechanics to get it solved but with no luck. (live in a small country town not much here)

The car has been serviced every 5000k,

list of parts that have been changed so far are

O2 sensor

fuel filter

spark plugs

coil packs

afm

fuel pump (bosch 040)

Auto was serviced at 100000k

timing belt (gates)

tensioners

all fan belts

as you can see it is starting to become a bit of a spend on all these parts

If anyone has any possible ideas it would really help out.

No idea. I would have said AFM but you changed it. Are there any mods like intake or venting bov? I would suggest going back to standard for a try if there are. Sounds like its running lean off throttle.

Remove and clean the AAC valve, back of the engine near the firewall. See link in my sig (not my tutorial but a bloody good thing to know)

to ad to this i have a standard bov and it has been checked and it is not leaking (new base gasket) I have also removed and cleaned the AAC

took the car to the local nissan shop today, They had told me last week that they could look at the car and see what the problem might be. Guess what. They refused to look at the car at all and said i would be on my own in fixing this problem. His reason was that he was worried that they would not be able to find out what it might be and that they were happy to take my money and not fix it. (they have seen the car before, he nows what it is and has ordered parts for it before) Dumb shits.

anyone please,

can you help

check the basics?

when did the problem occur?

whats changed since it started happening?

assume stock bov and intake setup? confirm? yes/no

assume standard boost? confirm yes/no

have you tried ECU reset?

have you checked idle RPM (sticker on bonnet identifies target idle RPM)

have you checked timing with timing light

the common basics will likely resolve this issue

it sounds like its stalling may even be auto box related

has that been checked since the auto box service?
