tooquicktostop Posted July 22, 2008 Share Posted July 22, 2008 After an eventful day of mapping and ACE cafe meet I was on my way home when stuck in traffic the car started to idle hunt then stutter and the AFR's started swinging about on the lean side, I continued on my way and nursed the car at very low revs home trying to keep the AFR's in the 14's, they wanted to go lean, I noticed the vacuum gauge on the turbo boost was sitting lower than normal on overrun and struddled to make boost, however I did not push it, the fuel pressure was all ok, got the car home but it was not very happy with a hunting idle What can I look for, there does not seem to be any boost pipes loose Link to comment Share on other sites More sharing options...
Guest Nicholas Posted July 22, 2008 Share Posted July 22, 2008 if it's hunting it's normally vacume line dean, have you checked, double checked and checked them all again? Link to comment Share on other sites More sharing options...

I have had a quick look thats all to be honest, not really sure what I am looking for, I have checked turbo intercooler pipes and they are all ok, the vacuum pipes are they on the inlet manifold ?

Homer Posted July 22, 2008 Share Posted July 22, 2008 I agree with Wayne ('kin ell thats a first ) Had exactly the some on mine once and it was a split in the fpr vacuum reference. Link to comment Share on other sites More sharing options...
tooquicktostop Posted July 23, 2008 Author Share Posted July 23, 2008 Vacuum lines look fine, after running through the symptoms with Ryan it could be the alternator as I did have a slight starting problem come from knowhere last night at ACE also, the poor current would cause the injectors to be erratic and this would in turn cause the AEM to try to compensate, this would cause the swinging AFR and on low speed a lean mix, as I was stuck in traffic the twin fans would have been on along with the lights, stereo etc and so would have shown up issue , I will check connectors to battery and alternator tonight but looks like it may need a new one, so I need two things How much is a new alternator ? Can anyone suggest a trailer to take my car to AFR from Purfleet in Essex, I have tried one company Matt suggested but he cant do it for a couple of weeks Link to comment Share on other sites More sharing options...

supradibbs Posted July 23, 2008 Share Posted July 23, 2008 DO yourself a favour and go for a PHR uprated alternator or get your fans setup with a thermstat but better still if you are using AEM get ryan to set them up through the AEM, These draw massive amount of power and really only should be running when needed Link to comment Share on other sites More sharing options...
tooquicktostop Posted July 23, 2008 Author Share Posted July 23, 2008 The AEM is running the fans and they run a lot in traffic, gave the car a warm up tonight and the signs point to the alternator for sure, turn on lights, fans etc and the cabin lights go dim and the AFR's go leaner Matt I have the car coming to you tomorrow via Les, a guy Mark has used at Phoenix Link to comment Share on other sites More sharing options...
