tommyputt Member 13 Member For: 13y 7m 27d Gender: Male Location: melbourne, aus Posted 05/03/12 06:06 AM Share Posted 05/03/12 06:06 AM Iv checked over the site a few times looking for people with the same issues but I'm having no luck.I'm having issues with a very abnormal idle for me. My car has does 160k full service history up 150 since then iv done it myself anyway. Since iv had it it's had a pretty good idle always around 750ish but a few weeks ago I got rough real rough. In park it's fine but when I put it into drive the revs die out to 500 and the car rattles like crazy. Iv recently put new coils. New ngk iridium plugs to solve the problem but nothing as of yet. It goes hard and under load its normal but as soon as I pull up at the lights the revs come down and the shakes set in. Iv also noticed when I put the defogger on and the ac it gets worse. The car has never acted like this it's got me stumped. All this started to occure after my last service. I noticed the oil I got this time has changed from semi synthetic to fully synthetic not sure of that's an issue.It's a bit of a novel sorry >.< Link to comment Share on other sites More sharing options...

Poor idle when in drive/reverse and stationary and rattles the whole car, car acts A OK off the line.Replaced the PCV value today, turns out that this is not the problem.I have cleaned the throttlebody in the past and reset the ecu, fixes it for a few days, then it comes back.Could it be alternator related, if idle quality gets worse when accessories are turned on?Also the poor idle only happens once the coolant is at temp (closed loop) Edited 08/03/12 02:30 AM by Barnesy Link to comment Share on other sites More sharing options...

Barnesy Donating Members 210 Member For: 16y 23d Gender: Male Location: Brisbane Posted 08/03/12 06:06 AM Share Posted 08/03/12 06:06 AM (edited) After everything went bang (timing chain tensioner snapped), I put the car back to stock; I had minor idles issues before it got tuned.So now running factory injectors, were tested before they were installed, coils and plugs (factory ones) are only 14mnth/20,000km old.Could be a few things like TPS, Idle controler.Will be putting a new o2 sensor in on the weekend, after 148K it might be time for a new one!
