Thanks, Rider. Wasn't familiar with this trader

Just after a set (4) of front brake pad retaining springs (47743-24020) for the 2-pot's if anyone has any? £12 inc p+p seem fair?

Thermostat stuck shut and engine overheated 'pushing' it back out through the reservoir?

Just a quick thread to highly recommend these chaps in Liskeard,Cornwall. Ross and Mark have sorted my girl out and she is running like a dream again (better than when I bought her 4 years ago) Although they are advertised as been GTO specialists I couldn't praise them enough with the supra. Im not saying that a standard car garage wouldn't have got to the cause of the problem (eventually) but I do believe that because they really know their stuff that they got it sorted much quicker and cheaper than many of the garages down here would have. Im not mechanically minded, sadly, so my interpretation of what was the problem and what has been done is not very concise but as I am looking to sell very soon Russ has said he will happily talk to any prospective purchasers should they wish but as far as I can understand the miss fire; see original thread - http://www.mkivsupra.net/vbb/showthread.php?t=203846&highlight=miss+fire Was due to ECU and Injector issues. The ECU its self had 'blown' but the cause of that was because one of the injectors was sticking open. Their ASNU injector testing machine was able to identify this and the injectors were then serviced and retested - http://www.sumiyaka.co.uk/html/tips.htm ECU was sent off to the ECU doctor in Plympton and then all re-fitted (along with a new Lambda sensor as this was also kaput) They also picked me up from the train station when I went for it and made what can only be described as the nicest coffee from a garage facility I have had! Well I hope this thread gets them a bit of work as its the least I can do. As for the car, I shall get pictures and get it advertised on here in the next month but from what I can see not a lot is selling on here at the moment, perhaps new prospective owners aren't aware of the site - which is a real shame, I wish Id have know about it before buying, i'm pretty sure I would have got more for my money. Hope everyone has a good day and drives safe Adam

Sorry Ric, noticed you had put come off - I shall check this!

Aaaah, I shall check this - would I be looking for breaks in the plastic and lose wires etc? Have just gotten off the phone from a mobile mechanic who is coming out tomorrow and he seems to think that there is a possibility that it may be the crank sensor...his girlfriend has a Scooby import and had very similar problems, diagnostic showed faulty lambda sensor and this was changed but made no difference, he then noticed a hairline fracture in the crank sensor that was letting in water and causing issues - sound plausible? Adam

Not as yet wiggy but it did cross my mind..how is best? Adam

Thank you for the reply, some responses for your further thoughts; Only one cylinder seems to be misfiring (3rd from front) the plug was soaked in fuel but dont expect this is the cause just a result of the problem. I dried it up and also swapped it with another plug and the same cylinder misfiring. Also swapped coilpacks and no change... Clips have been replaced and still it misfires. Im not sure whether there should be a reading and if so what it should be but we have hooked up a ampmeter for reading and the wires leading to that coilpack/plug barely made 1volt but Im not sure if this is normal or if it wont actually read correct when not hooked up to the colipack (incomplete circuit etc) Only say its running rich based on the incredibly rich smell of petrol out the exhaust..runs white but I don't give the engine long enough to warm up as I am worried about running it too long - perhaps I should get it to a garage and get diagnostics and compression test done. Thanks again for your help so far! Adam

Thank you Chris, thought this might be the one to look at...the orange check engine light was permanently on whilst the engine was running not after I started to perform a diagnostic check..is this normal? Adam

Just to add, the warning light is the picture of the engine, I looked at an old thread and it relates to; Engine/Gearbox Symbol - Malfunction Indicator Lamp.... Any thoughts? Thank you

Worrying thread..mine seems to have similar symptoms; New plugs were fitted and that sorted the missfire for a couple of weeks then it came back. Have replaced a couple of bad looking connectors and swapped coilpacks around and it is the same cylinder with the missfire. I now have an engine warning light, how do I see what the fault code is? Is there anything that would have caused a melted valve or piston? Adam

Thank you mate I shall get cracking on that after the new year and see if there are any plug issues. Am I going to cause any major problems running it on 5 cylinders to drive it to a garage...about 5 miles? Its running very rich but think I would benefit having a mechanic take over after Im out of options. Cheers

Well I have changed the coilpacks round and it is still the same cylinder missfiring so not them. Im going to check the connectors again and also plugs (they are new but want to make sure not faulty) Just wondering what is next if none of the obvious....injector, valves?? Thank you

As in try the suspected broken coilpack in another positon to see if it affects that cylinder?? I like your thinking! Adam

Just wondering what is the best way of checking the coilpacks. Car began missfiring this summer so I got the car serviced, the plugs were replaced and this sorted the missfire for 100 miles or so. I then replaced broken clips and I still have missfire on idle. Its constantly on 5 cylinders from start up, clear white smoke out the back and very very rich. In removing each coilpack clip one at a time and the car changing to 4 cylinders on all but one I feel I have found the culprit, the 3rd plug from the front (not sure which cylinder this is) can't be sparking as the tone of the engine didnt change when the clip was disconnected. This clip was replaced with a new one and checked several time so it shouldn't be that... Should I test the coilpack for a certain voltage (if so what should it read) or is there something else I am overlooking? Thank you all in advance for your help. Adam
