glasgow Posted May 2, 2014 Share Posted May 2, 2014 This morning while I was getting the seven out of the garage to get ready fore the 5 hours drive to GTKY7, I heard the engine as if it is running on 3 cylinders. Oh, nooo... nice weather and I should drive the car down south Anyway, car back into the garage and will sort it out next week, but a few questions please: A) how to remove the leads from the top of the spark plug please (yeh, silly question I know, but I am not familiar with those curved caps) B) I will remove one lead at a time to locate which one is the misfiring cylinder, but If I want to replace the spark plugs, what is the code for them please (K series, 2003, 1.8 Xpower) C) what gap measurement I should adjust the plugs to? D) I don't have a torque wrench, I will just tighten the plugs with plug socket - is this ok? E) Should I have the engine upto the operating temp before I remove the plugs (in order to ovoid snapping or over tightening the plugs)? F) I don't want to think of a worse scenario but if it is not just an old spark plugs what could be the other reason for the lumpy engine noise please?

Alastair B Posted May 2, 2014 Share Posted May 2, 2014 I'm not an expert by any means on this but to get this going here is my 2p worth... a. Use pliers to grip the top of the caps, can be tricky if the contact grips hard the spark plug...perservere and manipulate gently the caps whilst pulling b. NGK BCPR7ES c. 0.9mm IIRC d. Yes, not too tight and a touch of copaslip would be good e. Not necessary IMO f. I'll leave that to the expertise of Blatchat 😶🌫️ Do search on Misfire...lengthy post from April 14 could be useful, don;t know how to link posts! Good luck!

virden Posted May 2, 2014 Share Posted May 2, 2014 Did you run the engine for any length of time? Sometimes they clear when they get warm, mine does, but it's a X/F! Link to comment Share on other sites More sharing options...
revilla Posted May 2, 2014 Share Posted May 2, 2014 If your car is EU3 with coil-on-plug coil packs (not sure if this applies to EU2 too as not familiar with them) it uses a wasted-spark system with each coil pack driving two plugs. the two plugs and coil form a series circuit, so disconnecting one lead will kill BOTH plugs - making it harder to work out which one is faulty (the engine probably won't run on 2).

charlie_pank Posted May 2, 2014 Share Posted May 2, 2014 Much more likely to be a problem with a lead, coil or ECU than with the plug itself. Is there any chance that the plug-well is wet? Link to comment Share on other sites More sharing options...
Harry No Sheds Flatters Posted May 2, 2014 Share Posted May 2, 2014 Did you wash the car before you last put it away, if so and it is EU2 (has a distributor cap and leads) then remove each lead by pulling upwards on the rubber cap and check for water in the recess in the head.

Roger King Posted May 2, 2014 Share Posted May 2, 2014 If it really is running on three cylinders there is a very quick and easy way to identify which cylinder is "down". Run the engine for about 30 seconds with the car in neutral, then lick your fingers and quickly pat each exhaust header. Three will give a sizzling noise and one will give nothing at all. No responsibility accepted for burns, etc. Common sense must be applied here to avoid injury.

glasgow Posted May 2, 2014 Author Share Posted May 2, 2014 Thank you Alastair for the information Virden, Didn't run the engine for long as it has never happened with me before. had the car for nearly 4 years and never happened Revilla, not sure of the type i have but here is some of pics Charlie and Capt: car was not wet I don't know what EU2 and EU3 are but hope the pics are clear enough for you expert men to tell me more information about removing the plug caps please.... Have to go now to start my journey to GTKY7... But keep the post coming please... cheers Link to comment Share on other sites More sharing options...

Myles Posted May 2, 2014 Share Posted May 2, 2014 When did you last run the car? I've just fired mine up after the winter (lives outside) and it wasn't terribly happy. Lumpy and coughing/farting from time to time. I checked the two most-easily accessible plugs - no obvious issues, clearly needs a good run to clear them up a bit, chucked some octane booster in the tank (fuel is probably a year old!) and fired it up again. It certainly can't be described as smooth as silk - but it seems much happier. I'll re tax it (and the Westie) over the weekend and mebbe get it out on the local roads to work out what needs to be done this year. Oh, that reminds me - another for Powervamp/odyssey 'batteries. There's no parasitic load on this car, thankfully, but it does live outside and hasn't been run for six months, I guess. The battery was happy to churn the engine until it finally pulled some fuel through and would sustain ignition - I used to have to do various rain-dances, ritual-sacrifice and so on to get the engine to burst into life after winter - usually in a panic on the morning of the mot...

mav Posted May 2, 2014 Share Posted May 2, 2014 its eu3 mine has done this a couple of times and its cleared itself as it warmed. GTKY7 would have been the perfect place to learn about tracing the fault and fixing. I think the plugs are NLP100290 in rover part numbers. you can get them at your local land rover agent - just ask for plugs from a 2003 1.8 petrol freelander.

glasgow Posted May 5, 2014 Author Share Posted May 5, 2014 Just an update.... The car sorted out itself... 😬 Turned the engine on today, at first the same misfire again with some white fumes from the exhaust. then gradually setteled down when engine reached the operating temp... Took her for half an hour drive and was completely fine.... Any explanation please? Thank you Link to comment Share on other sites More sharing options...

glasgow Posted May 5, 2014 Author Share Posted May 5, 2014 Quoting charlie_pank: Water in the inlet manifold Any reason for that....? Car was totally dry.... Had the car for 4 years, driven in torrential rain and never happened before! Link to comment Share on other sites More sharing options...
charlie_pank Posted May 6, 2014 Share Posted May 6, 2014 Parked on a slope in the rain? Rain comes from a different direction to normal? If the wind blows really hard from the wrong direction, the rain leaks through our roof. It has happened once in 6 years of living here. Link to comment Share on other sites More sharing options...
glasgow Posted May 6, 2014 Author Share Posted May 6, 2014 OK, I hope that's the reason... Thanks every one for posting.... Link to comment Share on other sites More sharing options...
Area Representative paul richards Posted May 6, 2014 Area Representative Share Posted May 6, 2014 ECU - it's like a small computer. Like your PC it goes a bit wonky occasionally (for no obvious reason) and needs to be rebooted. It's probably a similar thing. Glad it's sorted - you missed a good day at Stoneleigh on Saturday. OR - it could just be a little damp/condensation in the wrong place. Edited by - Paul Richards on 6 May 2014 10:55:17 Link to comment Share on other sites More sharing options...
I reply to every thread Posted May 6, 2014 Share Posted May 6, 2014 Quoting Glasgow: This morning while I was getting the seven out of the garage to get ready fore the 5 hours drive to GTKY7, I heard the engine as if it is running on 3 cylinders.
