r32 idle problem

my r32 seems to not want to idle below 2,000 rpm originally my throttle body would stick when the idle pin was screwed in( too lower the idle below 2,000 rpm) I have replaced the throttle body and it no longer sticks but still sits at 2,000 rpm. I have gone through idle adjustment procedure and the ecu section seems to do nothing on my car and the valve control only lowers it to 1,500 rpm or so. I then cleaned the valve as suggested by others this seemed to work for a little while(sat at 1,200 rpm) as the car warmed up it rose very slowly back up to 2,000 rpm. Please help ps my car was auto to start with but idled at 2,000rpm in park then too.

check this thread http://www.skylinesaustralia.com/forums/sh...ead.php?t=69151

seems like this is fairly common, mine does it aswell. im gona fix the air regulator soon

im pretty sure the air regulator is my problem cos if i take it out for a drive and it really warms up the idle eventually falls down to about 1000. I haven't fiddled with my screw yet but i will once i get to to start idleing around 1000 to get it down to 750'ish.

From memory, the resistance (ohms) between pins 1 & 2 (the top 2) should be 0 when the throttle is closed.

A quick check would be to remove the plug while the engine is running, and short the 2 pins on the loom side with a paperclip. If the revs suddenly drop, then you need to adjust the TPS.

      My BMW 335i

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.

      Careful with posts like that around here without the flame suit on @cobo_11! 😂😂 My 330i journal is on here too. That car was so good and super reliable. We still have a 130i in the family which is almost identical to the 330i and easier to find in manual. It has also been almost faultless over the 6 or so years in the family.  I used to want an M car a lot more than I do now but if I'm honest and without trying to sound like a wanker, I can get such good performance and handling out of my 335 without needing to worry about all the crap that goes along with M car ownership. I don't need to worry about my bearings or subframe issues or the cost of replacing brakes or suspension or whether it has been impeccably maintained. And I can leave it places and not get upset when it's always filthy.
