NAAAAAFIN here in essex

....And fit very well they do too,i noticed an immediate improvment in feel!

Well..it`s no longer intermittant! Changed the plug today,was a little concerned as, although the tip is fine and looking good, there is a small bit of oil around the washer/seal which i found odd,so did a cold dry compression test got 147ish, is that ok? Tested coilpacks 2&6 (as these are what i initially swapped)by attaching the old spark plug and couldn`t get a spark off either pac,so could somebody give me an idiots guide on how to do that.I did earth the plug by touching the plenum both times.Listened to the injectors all were ticking although #6 did seem rather rapid, I`ll have to do it again as i`m not 100% on what i heard. Certainly could not get an ohm reading this time, nor a stable voltage..but i was fffreezing by then. Anyway got what seemed like all 6 for a second then back to lumpy running,from cold. Getting a code 55 so would assume the looms signal is ok? Have an injector being sent to me by a very generous Sussex Stu,so least i can compare ohms etc.Thanks again to joely for the comp tester..hope you`re not feeling so damp today! So next thing is to try a cold test on the other cylinders to compare, as don`t really fancy trying to get the car up to temp if it`s running like this in case more damage is caused.AH NUTS looking into it i seem to have done the test wrong,do i really have to remove all the plugs? also i had replaced the balance bar and it was cold.AND i didn`t full throttle..DOH serves me right for doing when feeling rotten.Another idiot guide ?

thanks

I`m really really hoping it will be this,you think cos they`re new they`ll be ok,but cheapest option first eh..he says. New years resolution...pray more!

Will call you in the a.m Joely,cheers bud. Will be getting around to all that Pete, just finding the time and decent enough weather.Will give a more indepth history of the problem when i get some time to myself. Have a good idea what to do now thanks to you lot and all the help.Watch this space!

no mate, when could i borrow it? Am pretty easy time wise this week.Thankyou.

ok,will do that then,is there any chemical treatment for this rather than removing the head? Also a big thanks to everybody that has offered help/advice.These things always seem to happen when you`re skint!

yeah, they are actually new this past summer although that does not mean i haven`t got a bad one.

No that`s a job for tomorrow, been too busy to check, conzult yes, computer no,missus killed it.Don`t think it`ll be valves as i get the impression it`d be foobarred all the time,moved the car today and as before when cold all is good! I`ll see if i can borrow a couple of coilpacs too.Then see what transpires after i get the new plug in on monday. also i`ll check for leaks,sure i have tester somewhere,just hope my tyre inflator can shove air in there quick enough. lol. Bloomin cars..think i`ll get a horse.

oh, i see. any idea what the box(not the ecu) is on the other side?

Are you insuating that Craig in some way..resembles..A turtle!!!? I will remember that expression :lol:

Now that i have checked, all seems ok, although i will track down the pins for #6 and make sure all is secure. Also,apparently the series 2 ptu does suffer from a fault with the connectors.Similar to ecu in that the pins can get pushed back a bit. Something else to check!

Well i know didly squat about welding so i`m impressed! You`ll get there in the end...then the bugger won`t start..he he!

Yes, i feel slightly insane at the moment. Just had a nightmare with my daily runner dying on me as well. Distributor had gone, and get this, the carburettor had started to undo itself from the block, no wonder the bugger was backfiring! Could move the whole thing by hand..think i`ll find my threadlock! Can turn my attention back to the zed now..joy! Do a compression check 1 when cold and 2 when warm. Stuck valve???? Would this only occur at certain temps then?

No, not yet. I`m hoping it`ll be something as simple as that! Fingers crossed.Also to add, when the cylinder goes down the engine vibrates a bit, i`m putting this down to being out of balance at the moment,was this the case in anybody elses?

Sod it, i`m gonna start burning my farts!

Hi all, right, my problem would seem to be an electrical one so will run it past you all for suggestions. Narrowed the problem to no.6, the cylinder is fine when cold and so far ok when restarted straight after shutting the engine off.The problem occurs when left a while, nothing..removing the coilpack connector makes no difference to the engine note, the same with the injector. I`ve recently replaced the loom so all is good with the connectors, the ptu is a new series 2 with a new loom. So there seems to be an interruption in signal when warm. I`ve swapped coilpacks to eliminate that side of things. Have a new spark plug to pick up, have a new cas, also have spare relay. Tested injector ohm when problem/not firing occurs and got 12ohm so assume it`s ok unless i`m missing something, as don`t know much about injector failings? Can anybody tell me what i should test and the components of the firing chain. I assume it`s ecu/connections,relay,cas,ptu,coilpack/sparkplug & injector.Which of these can affected by heat? HEEEEELP! Please..i thank you.:wacko:

I`ll give you banter.."£"!"$&%*)*)*++**!

still doing it...grrr and i notice that when i switch the winscreen blower off the revs drop to almosst zero before the ecu pulls it up again. I know the idle units fine with no leaks so not that.now have new series 2 ptu fitted so not that. gonna get a new cas off a member on monday.this is an electrical problem for sure only thing left after all this is the injector itself i think.

that`s my line! HAPPY XMAS TO ALL!

Rage..all day long. Still fresh as the first time round.

hat off to you!

Well after about an hour...no kidding! managed to get in the car,twas a zed popsicle! Checked the connector and managed to turn the bolt another turn or two so may hopefully have been that! Just need the road to reappear from under the ice now lol! Bonnets still frozen shut. I now remember not wanting to over tighten the connector when i replaced the loom, as i was led to believe it could cause the very same problem! Would make a bit of sense with metal contraction and expansion, especially in this weather. Cheers for the tip!
