  1. Hi Simon, and welcome! I have a 1986 S3, they are great cars and fairly easy to work on. I dont get too involved on the engine side of things, i have a good mechanic for that. The rest though you can learn as you go, which is basically what i did. This forum is the best resource for that, great folks with sound advice. I bought my car after it needed a lot of work and now its almost finished but being a classic there will always be something else that that needs doing. I just take my time. I dont know anything about your car but it looks good and im sure someone will know it and be able to give you more info... My sunroof is factory but without seeing closer pics of yours it would be heard to tell.. All the best
  2. My local Classic Car Show, i only went along to view the cars but i was put in the VIP area anyway! Caused a bit of a stir being the only Esprit there....
  3. Yes as above... NA Naturally Aspirated
  4. Thanks folks and apologies for the delay in responding. Steve, it is on my list to replace the Dizzy, but Jim in the meantime im deffo trying your suggestion. I never thought of that but it makes sense to give it a go. Christian, i cant believe something could go wrong after a certain amount of time but for me it also seems to be a particular bit of road which has nothing significant about it. maybe there is a 'government facility' that is nearby which is interrupting the Lotus Flow! Ill keep you posted! Brett
  5. Damn it!!!! You guessed it.... it's back. luckily i was on a fairly straight bit of road and i think i've worked out WHEN it does it.... Driving at a low speed of 30 in 4th gear so almost like its ticking along. This seems to be the time when i can feel its about to happen, i.e a slight hesitation then followed by the kangarooing again. Again it is only when the engine is warm. I think possibly the only way is a rolling road now....... Grrrrrr, close but no cigar!
  6. Cheers Scott, yes this is the one i bought which in the description does mention the GM part number above https://www.ebay.co.uk/itm/Ignition-Module-fits-RENAULT-R5-403-40J-1-4-84-to-89-C2J782-CI-7701021955-New/333852780890?epid=1754280237&hash=item4dbb2d295a:g:xMUAAOSwt4Nf-n0f Happy Days! (so far)
  7. lol....lets not tempt fate John. All help is good help!
  8. So i went out for a spin today....maybe 40 mins of driving with no problems! Still early days but i think the ignition amplifier may have sorted it! Makes such a nice change and the sun was shining too... Things are looking up
  9. Yes thats correct John, just the module from the AB14 swapped to a new one.
  10. Hi John, so far ive only been out once due to this crappy weather. It got up to temperature and didn't stumble. I'm not holding my breath just yet as being intermittent it hasn't always happened every time. I will however get oput again as soon as i can for a longer ride and more often. Constant testing is the key (good excuse to get out and about lol). I shall report back.....
  11. ah ok, i thought it was heat related. Does anyone know the best thing to replace it with?
  12. .....of lining the coil box in the silver heat tape stuff? mine has all but disappeared and im wondering if to leave it or re-line it? Regards all
  13. I changed mine to LED's. Before, i could barely see the instruments at night, after was a massive difference. I also took the dials apart and put reflective tape around the insides. Im not sure it made a big difference in that respect but overall it was so much better!
  14. Hi yes it is a DLB198 form SJ's. Ive also got a spare from PNM
  15. Its really hard to say as they all have different numbers on them, other than buying a complete unit for £200 odd from SJ, its a case of trial and error i think. I used the ref GM 1875990 that Scott mentioned as a guide.
  16. Hi folks, apologies for the delay in responding, i've been (to the best of my abilities!) fault finding all week to see if can make use of all these great suggestions to solve my problem. First of all i took the carbs off and gave them a good clean and blast through. All seemed ok. I also checked the float heights which were correct. I did find one o ring that wasn't there on one of the idle mixture screws which has since been replaced. I also contacted Eurocarb regarding the tiny filters above the float needles as although they were there, they are tiny and were a bit crushed. On their website they were discontinued. They advised they were only used by Lotus as there wasn't a Banjo filter. On mine there is a banjo filter so although ive kept them ive removed the very tiny ones. All back together and back on the car with new gaskets etc and new O rings also on the spaces between the inlet manifold and carbs and set to the correct gap. I also balanced them using my Carbtune too. New Petrol also. One thing i did notice was the fuel pipe coming going into the carb was cable tied to the water pipe. Now i did read somewhere else about fuel evaporation if the fuel lines are near anything too hot so i unclipped it so its no longer attached to the pipe. Took it out for a spin..... and it still kangarooed after approx 15/20 minutes once it was up to temp. I think i'm ruling out fuel now as the problem so looked at the electrical side of things.... Again, the plugs, leads, coil, dizzy cap and rotor have all recently been replaced (prior to that it still kangarooed anyway). As a few of you have mentioned the Ignition Amplifier. The one i currently had, i replaced the 'hardly any' heatsink paste with some new gunk, but still it made no difference. I did notice the black amplifier metal box did get very hot but i guess that was the paste spreading the heat (the coil wasn't even warm). So i bought a new module for £10 which took a few days to come from China. It looked exactly the same but when i put it in the car ran on pretty much half power, so i had another look and after much perusing i found one from the uk on Ebay for £18. It has since arrived and will be swapped over probably tomorrow for me to try. I will report back with an update then. Someone also mentioned unplugging the rev limiter but this also made no difference either. My only other option after this is the Distributor. This bit scares me a bit as i dont want to muck up the timing if i have to remove it. I cant see any breaks in the wires from the pick up either and i have wiggled them a bit when its stumbling at idle and it makes no difference. So i'll check the ignition module replacement next and report back. Just wanted to give you an update Regards all Brett (Steve, i did check the wires on the alternator are attached as they should be and the voltage is ok) (Andy, i also bought some neon sprak plug testers and put them on... no obvious sparking issues while the stumbling happened)
  17. Hi Ian, as i mentioned above, i Haven't mainly due to the fact they are so expensive for new ones just to test it, i will look around for a 2nd hand one
  18. Do you mean the one in the pic above?
  19. Yes i ts in the box attached to the boot with the coil. I did take it apart to check the internals and no broken wires. I also replaced the heat sink paste as there was hardly any of the original stuff left.
  20. No i haven't. I dont have a spare and they are quite expensive. I will look at finding maybe a second hand one to see if it helps. I'd also like to know!! It could be the answer to all my problems......
  21. I have checked the wires to the distributor, and they seem fine, i.e no breaks, and the plug part to the coil box is fine also . The tacho does drop when it does run rough. The other day it sat on the driveway and the stalled when it started to run rough about 10/15 mins after starting.....
  22. John, i had a look at the air intake including all the pipework on top of the right tank. I temporarily took away the pipework and attached a pipe direct from the 'Ear' to the airbox. The problem still persisted although i prefer the way it is now. To think the air intake normally comes from the boot seems a little weird anyway. Thanks Steve, i did check this and all wires are attached. I will take the airbox off though to double check, and while im there i will take another look at the dizzy and rotor etc...... I shall report back Cheers guys
  23. Yes, looking in the parts list, it only lists the thermal valves for HC Engines...
