Fee Posted February 26, 2009 Posted February 26, 2009 Went out this morning to pick up a parcel. 5 minutes or so on the way and the check engine light came on ....just after the car just spluttered and cut out. The car is starting again, but only stays ticking over for a short spell, lumpy idle and then cuts out again. There is no power, I can put my foot down, but the car doesn't go anywhere Haven't had a chance to look at it yet...had to beach it and get a lift to work. Any thoughts? I was thinking maybe an intercooler pipe had blown off....but the 'check engine' light seems a bit strange. Cheers Fee
fai17 Posted February 26, 2009 Posted February 26, 2009 Did you give it some beans(full throttle)before the problem arised? A popped intercooler hose would show that kind of issues that you are discribing. Don't i wouldn't expect a hose to pop unless you have been giving it some unless the hose clip is pumped! Either that its a maf or something!
Fee Posted February 26, 2009 Author Posted February 26, 2009 Na, driving through traffic so pretty tame the whole way It's been driving a bit 'rough' the last couple of times I've been out in it....kinda stalling/pausing mid acceleration
Big Daz Posted February 26, 2009 Posted February 26, 2009 Ooo youv'e broken Adams Car !! Better break out the Skyline Crank Position Sensor or MAF gets my vote, but I would have though MAF would just reduce power rather than none at all. Does it have the single coil pack on the top of the engine? Maybe thats on its way out - intermittant sparking. Daz
Fee Posted February 26, 2009 Author Posted February 26, 2009 I've broken it....for the second time! Should have just bloody taken the Navara....the only reason I took the Impreza was because it was facing the right way!!!

LOL, thats got to be the laziest thing I have ever heard Well you are going to need to take the Navara now to recover the Scoob If you need a hand I am in Abz today
RA Dunk Posted February 26, 2009 Posted February 26, 2009 cam/crank sensor is a classic cause of hot start problems
Big 'D' Posted February 26, 2009 Posted February 26, 2009 Have you checked your ECU for fault codes yet? The car can tell you what is wrong with it. How to read ECU Fault Codes What the codes mean. A simple one to try first would be to unplug your MAF sensor then start your car, if the car idles and revs better it is highly likely it is that, but to be 100% certain the ECU fault check will point you in the right direction. Cheers Iain

Does it have the single coil pack on the top of the engine? Maybe thats on its way out - intermittant sparking. Daz The car will not start if the signal from the Crank or Camshaft sensors is not seen by the ECU, if the MAF is not working the car will start but will idle very roughly, very poor throttle responce and will cut out alot. (simple test is to disconnect the MAF and start the car) if the idle is better it is pretty certain the MAF is at fault but the ECU fault check that I posted earlier is the best way of finding out what is wrong with your engine when the CEL comes on. Cheers Iain
Fee Posted February 26, 2009 Author Posted February 26, 2009 Thanks, I will check it out at lunchtime Cheers for the offer Daz, got my sister coming down to give me a hand towing it home, won't be able to look at it properly until the weekend
TrackScotland Posted February 26, 2009 Posted February 26, 2009 Women eh!! sounds like is running the same as it would without the AFM connected... seems a bit sudden for it to just die though, but maybe the hesitation/stutering you felt the other day was it starting to fail. Still - Check the fault codes, see what it flashes up. Hope with it being a SARD ECU it'll still do it correctly! Engine light wouldnt come on to warm you a boost pipe was away to fall off Be great if it did though!
Fee Posted February 27, 2009 Author Posted February 27, 2009 No, not had a chance to look at it properly yet. Will do over the weekend
Fee Posted March 1, 2009 Author Posted March 1, 2009 Checked the fault code this morning.....22 - Knock Sensor I'm no wiser!
TrackScotland Posted March 1, 2009 Posted March 1, 2009 It could be fecked, but would it really cause it not to start etc :S I know it had a habit of fouling plugs when being used for short journeys/start - stops etc.... suggest disscontecting the ECU for a while, cleaning the AFM and fitting fresh or cleaned plugs Do a google search on cleaning fouled plugs if you cant find suitable one this afternoon. Woman
TrackScotland Posted March 1, 2009 Posted March 1, 2009 bottom end anyone? doubt it.... or rather hope not.... I hope fee would have heard some warning signs on that :/
Big 'D' Posted March 1, 2009 Posted March 1, 2009 Faulty knock sensor would only put the car into limp mode. Was that the only code? Cheers Iain
Big 'D' Posted March 1, 2009 Posted March 1, 2009 Have you tried to run the car with the MAF unplugged yet? Cheers Iain
Fee Posted March 1, 2009 Author Posted March 1, 2009 Just the one code. Just cleaned the AFM (which was really manky) and it seems to be better (it revs when I press on the accelerator now)....still not 100% though i don't think

Cheers Iain
TrackScotland Posted March 1, 2009 Posted March 1, 2009 (edited) quick Q.... AFM's in STi V4 TypeR's ... are they always the orange labeled ones? also see - http://www.trackscotland.co.uk/forums/viewtopic.php?t=923 Edited March 1, 2009 by TrackScotland
Big 'D' Posted March 1, 2009 Posted March 1, 2009 quick Q....AFM's in STi V4 TypeR's always the orage labeled ones??? also see - http://www.trackscotland.co.uk/forums/viewtopic.php?t=923 Yes I think so mate also the same as the Ver 3/4 Sti. Cheers Iain
