magrillz Posted June 19, 2012 Share Posted June 19, 2012 Hi All, I was wondering if you could help me and if anyone had experienced the following before: Car is a 2008 313GT completely standard and done 33k. Car doesn't do very long journeys, only 12.5 miles to my work. When the car engine is warming up it intermittently judders at around 1500 - 2000 rpm. This is normally only when I'm being very gentle on the throttle and just cruising along. If I get my foot down the car seems fine through the rev range. I noticed it a while ago and got Nissan to check it under warranty but it came back as no fault found. To be fair they still re-set the throttle bodies in case this helped which it did seem to but the problem is back again (came back soon after but difficult to reproduce sometimes). I'm going to try and reproduce the issue in front of a Nissan Tech but just in case I can't, has anyone ever seen something like this? After doing a search I wondered if it could be the MAF sensor or if it could be something to do with the throttle bodies still? As always thanks in advance Quote Link to comment Share on other sites More sharing options...
Clown Posted June 19, 2012 Share Posted June 19, 2012 I thought it was just down to being a japanese car Quote Link to comment Share on other sites More sharing options...
Mikesding Posted June 20, 2012 Share Posted June 20, 2012 Im not sure I completely understand what you're saying is the problem, but my 313 GT seems a bit juddery in first and sometimes second gears when in this rev range - as in the rev meter will flutter about unless im actively accelerating. Does that sound like what your problem is? Quote Link to comment Share on other sites More sharing options...

Does that sound like what your problem is? Hi Mikesding Thanks for the reply. The car seems fine on tick over it's literally only when driving. It can be any gear but I'm normally in 2nd or 3rd, at around 1500-2000 rpm. If I'm trying to keep the revs at around that area, say in 2ng gear driving down the high street near my house, then it starts juddering/stuttering. It's as if I'm on and off the throttle. Started off quite mild but now even passengers notice it. Almost like the cars going to cut out or something. If I was to keep the revs at 2500rpm it is fine. Once the car is properly warmed up it doesn't seem to do it any more but also doesn't do it when the engine is very cold when the cold start system keeps the revs a bit higher. It's basically a bit of a bugger to try and reproduce on demand but will try and get over to the dealers to see what they say. Just thought someone may have seen similar. If I ever get to the bottom of it I'll post my findings but in the mean time maybe just get my foot down and get the revs up. Mat Quote Link to comment Share on other sites More sharing options...
soimafreak Posted June 22, 2012 Share Posted June 22, 2012 Sounds like there could be an issue with a sensor somewhere, I would take it to the garage to get it checked out. Quote Link to comment Share on other sites More sharing options...
imhereithink85 Posted June 22, 2012 Share Posted June 22, 2012 Are you driving away before the revs settle down from the high idle at cold start? What I noticed was if I drove away before letting the idle settle down below 1500rpm it would hesitate to go lower when driving as the engine was trying to keep it at a high idle. Meaning the car drove as you are describing. What I do now is sit for 30 secs and let the idle settle down, then drive away and all feels good and normal. Hope that makes sense?

magrillz Posted June 22, 2012 Author Share Posted June 22, 2012 Yep, makes perfect sense. I'll give it a go and see if it makes any difference but in the mean time have booked it back in with Nissan. Will report back on what happens. It's out of Warranty but they said they can ask Nissan for a good will gesture as it was in Warranty when I reported it last time. Don't hold out too much hope. Thanks for everyone's suggestions Mat Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted June 22, 2012 Share Posted June 22, 2012 I found an earthing kit sourted out a slightly rough idle on my Zed Quote Link to comment Share on other sites More sharing options...
Ekona Posted June 22, 2012 Share Posted June 22, 2012 Run a can of 10K Boost through it. Amazing stuff, promise. Quote Link to comment Share on other sites More sharing options...
magrillz Posted July 10, 2012 Author Share Posted July 10, 2012 Thanks again to everyone for the replies. Nissan had the car for two days and say they couldn't reproduce the fault but did notice it was a bit hesitant very briefly so reset the throttle body (did that last time). In short no fault found and an hours labour charge... Oh well! The annoying thing is I drove it away and within seconds it did it again. To be honest It's not the end of the world as it only does it for about two minutes when the engine is at a certain temp. Might have a go at cleaning the MAF sensor and throttle body but guessing if either were dirty the issue would be more permanent? Failing that might pop into Abbey Motorsport if I'm ever in the Surrey area. Cheers guys! Quote Link to comment Share on other sites More sharing options...

magrillz Posted December 4, 2013 Author Share Posted December 4, 2013 I know it's been a while but thought I'd post an update on this. Apparently Abbey MS have found an issue that presents itself with the Exhaust CAM control. There's a fix for this which Abbey MS can do via an UP-REV Remap. I was all set to get this done in the new year, however on Monday I had a service booked and decided to use Fuchs Titan Race Pro S Oil instead of Motul v300. I also had all of the Spark Plugs changed as the cars just hit 5 years of age. It's only been two days but since the oil chnage and spark plug change it's been fine and is driving much more smoothly with no annoying judder during warmup. Could a dodgy spark plug have cause this? I would expect a faulty spark plug to be consistantly faulty rather than inttermittent? I'm not very good when it comes to mechanics though If it does come back again I'll definitely be getting the remap done from either Abbey MS or Mark mentioned they are partnering with TDI-North in Warrington which is a bit nearer to me. Just thought I'd let you guys know in case anyone else has the problem. Cheers Mat Quote Link to comment Share on other sites More sharing options...
Roscoe Posted December 4, 2013 Share Posted December 4, 2013 I found that when I changed the oil to motul 0w-40 the stuttering did become much less harsh, but after about 1000 miles it returned. I don't believe this is a spark plug issue as after abbey carried out my remap the problem had completely gone. Quote Link to comment Share on other sites More sharing options...

I feel much better knowing that if it comes back theres a fix for it Quote Link to comment Share on other sites More sharing options...
