Whitesupraboy2 Posted September 23, 2007 Share Posted September 23, 2007 AUTO TT BPU Plugs: IK24 (8months old) Driving along fine and I come to roundabout as i pull off I put my foot to the floor for kick down but instead get a full splutter. I quickly change lane to head off to a housing estate. I now cant give the car any throttle at all (or so I thought) and it just starts spluttering. Not misfire sound as such, Best way i Can describe it is kangaroo petrol but without as much energy, so splutter (soft go), then dead then splutter again. If i take my foot off the accelerator it trundles along fine on the idle, I then find if i give it less then 4mm travel on the pedal the car will accelerate without a splutter. This up to revs of about 2000RPM with that much travel. So I coast back at 30 - 40mph no problem as thats the speed limit, as coming back idecide to see if its behaving itself now and sure enough put my foot gradually down and turbo's come online and everything is fine, smooth silky and fast. Does anyone have any ideas? I cant tell if I had a misfire at idle or not sorry, but if i did im sure power on boost wouldnt be happening. Link to comment Share on other sites More sharing options...

hadyn Posted September 23, 2007 Share Posted September 23, 2007 Id check your plugs and are you running on the stock fuel pump? Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted September 23, 2007 Author Share Posted September 23, 2007 nope walbro fuel pump. I think im going to change my plugs as a precaution. Link to comment Share on other sites More sharing options...
hadyn Posted September 23, 2007 Share Posted September 23, 2007 How many miles are on your IK24s? From experience Ive found that IK24s dont seem to last longer than about 15k miles tops A plug or plastic connector might have come loose as well, which could cause your problem Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted September 23, 2007 Author Share Posted September 23, 2007 Cant be more then 8000miles tops really. I know i had a couple of brittle plastic connectors last time, so ill get replacements too. Im still not convincing plugs though purely due to fact i had full power on boost next time it came alive.

SimonB Posted September 23, 2007 Share Posted September 23, 2007 It could be a dodgy connection to something like a fuel cut remover or RLTC. Or a dodgy coil-pack connector. Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted September 24, 2007 Author Share Posted September 24, 2007 I was wondering that, just to add when i parked up put it in neutral and rev'd it, it rev'd fine up to 3000rpm, i stopped at 3000rpm i didnt find the need to rev any harder. Im now wondering if maybe an injector got stuck. Link to comment Share on other sites More sharing options...
Homer Posted September 24, 2007 Share Posted September 24, 2007 Did you notice any smoke from the exhaust? Did any of the engine management lights come on? Checked for fault codes? It does sound very much like a boost pipe had come off, so certainly re-tighten all the clamps on the IC pipework. IME, once the plugs start playing up, they don't tend to suddenly start working again, so as others have said I've look towards coil pack connectors and also the FCD is securely wired in.

Whitesupraboy2 Posted September 24, 2007 Author Share Posted September 24, 2007 No engine management lights came on, if they did i would of pulled over instantly. I'll change the coil pack connectors. Link to comment Share on other sites More sharing options...
