I was wondering if anyone has or has had the same problem as me. im driving my car and every so often (cant pinpoint a specific rev range) it shudders. the pedal goes to floor, the engine splutters, but there is no power at all! this is only for a few seconds and then everything seems to be ok again. but sometimes it is so serious, i have to pull over. one time the catalytic converter light came on for a moment. its like a giant miss! originally i thought it was the afms, so i took them off and had them cleaned. but the problem is still there. i know i should take it to the mechanic. but was wondering iif i could fix the problem myself for the meantime. any suggestions? car is an r32 gtr.

Arrrrrrgh! help! i have taken it to the mechanic.... and you know the story.... the car is well behaved and cannot get the problem to occur at all. just now i changed all the spark plugs, from 6's to 7's. the car went in for a major today, and my mechanic (chapman automotive) told me that the spark plugs were ok. just to be on the safe side, if it were faulty spark plugs, i wanted a set i could changeover to. after changing them over. it drove quite nicely. but then, there it was. but this time, when it did happen, it was terrible. my car was crawling shuddering and spluttering all the way home. i had to pull over a few times. the car just wouldnt go! when i pushed the accelerator, it burbled thru the whole rev range. now when it sits, it idles nicely and then drops to the point of stall (but doesnt) and then idles nicely again! i am too worried to drive it anymore. please help! my mechanic is very far away! in this service the afm's were cleaned. so that eliminates that possibilty. please help!

    • What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!
    • Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !  
    • Thanks, will do that.  Thankfully they still feel great.
    • Yeah man, absolutely. You can try pushing me all the way in swapping the R34 for an E9x M3 
    • It's almost certainly going to be some amount of pads compound transfer onto the rotors. It will probably go away after you've run them for a bit. If not, pull it all out, lightly sand the rotors, scuff the pads, and rebed.
