Guest Carsten Posted October 6, 2009 Share Posted October 6, 2009 Hey guys, yesterday i tried to start my car. It moved for about 10 yards then started to act wierd. No acceleration, revs jiggled, and a wierd noise came from the bottom of my car (aprox. near the downpipe) Also there was a slight smell of fuel + check engine light. 8Hours later i tried to start the car again to move it to a garage... Suddenly everything was fine, engine reving, acceleration and so on. Today morning the same thing... Fuel smell, wierd sound from the DP (no sounds at the engine itselft i think), check engine light. Revs are at a constant 1k rpm. I couldnt read the failure code out yet. (had to go to work asap). Maybe you could help me out here. Are those commond syndromes? greets Quote Link to comment Share on other sites More sharing options...
Nic Posted October 6, 2009 Share Posted October 6, 2009 NA or TT? From your description, it sounds like it might not have been firing on all 6 cylinders. If it's not firing on one or more of the cylinders it will sound like a bag of hammers, it won't rev and you will get a strong smell of fuel as it gets spat out through the exhaust. Have you cleaned the car recently and got water in the engine bay? First thing I'd do would be to remove engine cover and check for water around the plugs. Give all the electrics a good spray with WD40. Quote Link to comment Share on other sites More sharing options...
Guest Carsten Posted October 6, 2009 Share Posted October 6, 2009 (edited) TT. Didn´t clean it last days. But i´ll check for water. edit: I dont think it could be the cylinders. Thou i would hear it on the engine itself (which i dont). I just a hear a wierd sound from the hose (near DP) Edited October 6, 2009 by Carsten (see edit history) Quote Link to comment Share on other sites More sharing options...
Guest Carsten Posted October 6, 2009 Share Posted October 6, 2009 No error code saved. Just the Cruise Contr and Slip Cont are flashing. ?!? Quote Link to comment Share on other sites More sharing options...

adnanshah247 Posted October 6, 2009 Share Posted October 6, 2009 thats a strange one! havent seen that before. Were's Homer when you need him. Quote Link to comment Share on other sites More sharing options...
Guest Carsten Posted October 13, 2009 Share Posted October 13, 2009 Changed Coilpacks and spark plugs. Cylinder 3 doesnt work when cold. If engine heats up its okay ?!? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 13, 2009 Share Posted October 13, 2009 Injector? Resistor pack if it uses one? When you said you changed the coil packs, you mean you fitted all new ignition coils, or just the connector bodies? Quote Link to comment Share on other sites More sharing options...
Guest Carsten Posted October 13, 2009 Share Posted October 13, 2009 Just the bodies. Yeah i also think of a faulty Injector. Lets hope so! Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 13, 2009 Share Posted October 13, 2009 Here a small video: http://www.youtube.com/watch?v=ctGe2bWf0zI I was rather expecting that to be a vid of the car running badly, not a flashing light on the dash Is the noise you hear down low just the engine pinking from low revs/overfuelling? Have you got the first Cat in still, it might be blocking up intermittently? Is yours a euro spec version with a MAF? Quote Link to comment Share on other sites More sharing options...
Guest Carsten Posted October 13, 2009 Share Posted October 13, 2009 Couldnt get a video of the car running badly sorry. (engine was already warm and error didnt occur) The sound is not the engine changing revs. But, as my garage found out today, it is definetaly a cylinder not doing his work (if its cold) Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 13, 2009 Share Posted October 13, 2009 It's possible to disconnect the plugs from the injectors without any dismantling, so you can find out which one is the probelm cylinder easily enough. Also you can check if it's always the same cylinder. Maybe a valve is sticking open - I've heard that before, it runs like a dog, will spit unburnt fuel out the back, and you get a metallic noise as the cam hits the shim bucket every two revs. -Ian Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 13, 2009 Share Posted October 13, 2009 Swap the coil packs around and see if it stops running on a different cylinder when cold. If not suspect an injector or injector plug, or injector resistor pack if it's not a Jap Spec. COULD be a valve, but it's not something I have seen on an engine that's not been left standing for years. Quote Link to comment Share on other sites More sharing options...
Hrenowsky Posted October 13, 2009 Share Posted October 13, 2009 Sorry for the hijack, but the same thing happened to me about two weeks ago. Went to grab a coffe, everything was fine. I left her parked for about 2 hours, and she didn't want to start, revs were jumping around, the check engine light was on, there was a strong smell of fuel and the car had no power. Oh, and an interesting bit, if i floored it the revs were chunky to about 2500 then normal to approx 3700, then a bit less chunky to 4000. And the revs stopped at 4k just like they would at the limiter I'm thinking it's somehow ecu related... Help needed! Quote Link to comment Share on other sites More sharing options...
Guest Carsten Posted October 14, 2009 Share Posted October 14, 2009 Thanks Ian and Chris. I´ll try that out, hoping that it is not a valve edit: It occured after i tried to ettc. But now everything is stock again. Dont think its the ECU. Quote Link to comment Share on other sites More sharing options...

Usually something to do with the crank position sensor on its way out i think? Quote Link to comment Share on other sites More sharing options...
Hrenowsky Posted October 20, 2009 Share Posted October 20, 2009 Fitted a new ecu today, thanks to m_life, and it solved the problem.:d Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 20, 2009 Share Posted October 20, 2009 Fitted a new ecu today, thanks to m_life, and it solved the problem.:d I personally think it's very rare, almost unheard of, that the ECu itself goes wrong. I think what you have there is worn pins on the ECU plug. You can refurb them for free although it's a tedious job - try giving the main ECU loom a few good tugs around while the engine it idling, that'll soon show up any loose connections. -Ian Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 20, 2009 Share Posted October 20, 2009 I agree Ian, I used to know a fella who had a business repairing ecus back in the days of the Lucas junk in the late eighties. 99% of units he got back in exchange were fine, just unplugging the old unit, spraying the contacts with switch cleaner, and refitting it would have solved the problem. Modern ECU's are very very robust! Quote Link to comment Share on other sites More sharing options...
Hrenowsky Posted October 22, 2009 Share Posted October 22, 2009 I tried cleaning the contacts using a three-stage cleaning solvents (cleaner, washer, protector), with no luck. The new one (ecu) worked instantly upon connecting. Quote Link to comment Share on other sites More sharing options...
