Apologies if this topic has come up in the past, but I have searched the forum and cant find anything that is close enough to my problem.
My '91 R32 GTR is very erratic at the moment, and the problem is now getting more and more frequent.
What happens is she will sometimes (condition is always from cold startup) idle at around 2000rpm, I'll drive a bit further, the idle revs will drop to 1200rpm, drive again and the idle revs are back up to 2000rpm. Once she's warmed up revs will be normal (around 1000rpm). And there's more...!
Whether cold or warm/hot/hard driving/switched off for an hour/driven again, she sometimes acts like she's choking and needs the heimlich manoeuvre to sort her out!! What happens is I'll accelerate up to just before 3000rpm and the engine will behave like I'm hitting a rev limiter. It will just not go over and bring second turbo in, the action is like on off on off on off, needle bouncing under 3000rpm, with pedal down/midway/easing on power-doesn't matter.
After alot of p*ssing about and looking a pr*ck (about 2 mins or so) she'll clear the problem and act as if nothing has happened!!!
Any help and info greatly appreciated as always....
