the_doc Posted March 30, 2014 Share Posted March 30, 2014 Recently purchased my zed which is an 06 JDM import. Didn't notice it on the test drive but when the car is cold the rev counter is stuttering/jumping around when cold which makes the car pretty jerky and annoying to drive until it warms up. It only seems to happen around the 2k/rpm point. Don't suppose anybody else has had a similar problem, also if so how did you rectify it? Changed the oil this weekend but it had no effect. Cheers in advance, Jay. Quote Link to comment Share on other sites More sharing options...
WhackyWill Posted March 30, 2014 Share Posted March 30, 2014 Sounds like it could do with a good service including plugs. Quote Link to comment Share on other sites More sharing options...
the_doc Posted March 30, 2014 Author Share Posted March 30, 2014 Yeah, the next cheap fixes on the list are to swap the plugs, clean the throttle body and then change the fuel filter. Fingers crossed one of the above should do the trick. Quote Link to comment Share on other sites More sharing options...
Ekona Posted March 30, 2014 Share Posted March 30, 2014 Clean the MAF, too. Quote Link to comment Share on other sites More sharing options...
the_doc Posted March 30, 2014 Author Share Posted March 30, 2014 I have some carb cleaner, is that suitable for cleaning the MAF sensor? Quote Link to comment Share on other sites More sharing options...
Ricey Posted March 30, 2014 Share Posted March 30, 2014 Yes mate I think it says on the tin 'will not damage o2 sensors' Sent from my HTC One mini using Tapatalk Quote Link to comment Share on other sites More sharing options...
Ekona Posted March 30, 2014 Share Posted March 30, 2014 Carb cleaner will be fine Quote Link to comment Share on other sites More sharing options...
the_doc Posted March 30, 2014 Author Share Posted March 30, 2014 Awesomes! soon as I get a bit of spare time I'll let everyone know how I get on. Quote Link to comment Share on other sites More sharing options...
the_doc Posted April 11, 2014 Author Share Posted April 11, 2014 Quick update on this, gave the front face of the throttle body and maf sensor a clean which seemed to reduce the stuttering. Next step is to remove the throttle body and clean it properly. I'll let everyone know if that sorts it.

the_doc Posted April 13, 2014 Author Share Posted April 13, 2014 Yup that doesn't work, onto spark plugs and stuff. Sent from my HTC One X+ using Tapatalk Quote Link to comment Share on other sites More sharing options...
WhackyWill Posted April 13, 2014 Share Posted April 13, 2014 I would have put a set of plugs in it first..! Might also be a HT lead or a coil pack braking down, Quote Link to comment Share on other sites More sharing options...
the_doc Posted April 13, 2014 Author Share Posted April 13, 2014 Yeah, it was the easy option this Sunday afternoon because I had a can of carb cleaner in the boot. Fingers crossed its a cheap fix!

the_doc Posted April 21, 2014 Author Share Posted April 21, 2014 Quick update, cleaning the throttle body didn't work. So changed the plugs today and they were knackered. Plug gap was massive and the electrodes were really deteriorated. Despite apparently being serviced On the bright side stuttering has finally gone and she's a pleasure to drive again.

the_doc Posted April 21, 2014 Author Share Posted April 21, 2014 If I'm honest I've only had my zed just over a month and I haven't considered it yet. Sent from my HTC One X+ using Tapatalk Quote Link to comment Share on other sites More sharing options...
the_doc Posted April 26, 2014 Author Share Posted April 26, 2014 Okay, may need a bit more help now. It appears the stutter hasn't gone away now so the symptoms have changed slightly. No fault codes shown from my friends obd reader, but it was struggling to connect. The car doesn't stutter on the initial 30 seconds from a cold start but is really apparent until ten minutes of driving has passed and the car is properly warmed up. Doesn't seem to be a misfire as the engine still sounds pretty smooth. However the revs rise to 2k rpm then there is a slight interruption and they drop slightly. When it does this you can hear a slight click under the bonnet possibly a solenoid or something. I have already changed the oil, spark plugs and also bought a coil pack which I swapped around all the cylinders in the hope a pack was beginning to fail. I also cleaned the throttle body and maf sensor. Any experts on here that can shed any light on this or anybody whose had the same problem? Don't want to spend silly money changing everything when its probably just a sensor. Sent from my HTC One X+ using Tapatalk Quote Link to comment Share on other sites More sharing options...
