  1. Thanks Derek, i knew you would have the correct name for the thing. I knew it wasn't the balance adjustment but struggled to put it into context. Put a couple of hundred miles on her since your lifesaving surgery and the engine is now running night and day better for them. Thanks again for the help. 

  2. No the factory set air mixture screw (adjusts the air gap around the throttle body butterflys when off throttle)I agree, 99% of the time it’s previous owners (or current in my case 😳) who have fiddled with it but this will be apparent with the AICV count (ie it will be low at full operating temp)

  3. Not if the tickover is too high. The ecm will drop the IACV to zero counts and has no further adjustment to lower the tickover. It then has to be lowered with the screw to allow the ecm to control the IACV again. This shouldn’t need to be tampered with as is set at factory however bigger injectors have been introduced and always a possibility of previous fiddling with said screw.

  4. Mine was a combination of AICV and and a bad O2 sensor. Also check your throttle cable is either a) not adjusted too tight

    b) Not binding on anything.

    On the Freescan check your IAC count once the car is up to operating temp. I recall from a conversation with Sailorbob this should be reading around 45. Im sure he will give the correct figures here. This can be set with the screw underneath the secondary injectors.

    Also I have RC injectors and not a fan. If you still have the Rochesters try swapping back. Did you use new o rings and happy they are seated as an air leak can cause high/uneven idle.

  5. Thread hijack, apologies in advance....

    How bizarre. I was literally just going to type an identical post. Postie dropped my new 15ltr bath off this morning.


    Mine however has the RC injectors installed.


    Does anyone know the correct o ring size for these please as i have a receipt from the p.o which states the Lotus service centre that fitted them upon request of him advised they were not happy that the o rings were the 'perfect' fit.


    C'mon Sailorbob this has got your amazing knowledge for detail written all over it!

  6. New MOT this morning with only an advisory for a rigid brake line which ill swap this week.

    Treated the car to a set of nice sticky rubber for the rear. The old tyres still had 6mm of tread but had gone off over time so i though i may as well go for something that wears a bit quicker and still will probably never get near the wear markers before they expire.

    The Exige lads seem to like em.

  7. Following on from the success of taming the tick over Sunday will involve an annual service. 

    Its also time to renew the brake fluid. I do get an intermittent ABS light blink to which i thought i would dedicate a few hours trying to resolve with a full bleed following the Delco Moraine walk through. 

    I know the braking system on the S4 is unloved and leaves something to be desired but given the option i would rather keep its originality.

    Continual problems down the line may seek me to entertain an ABS delete but not at this stage.

    I might even take some pictures...

  8. Good Job!

    Mine is R472AAH and was used as one of the motorshow cars when the update was announced. Painted in Nautilus Blue.

    According to the letter that came with the CoP it was signed off from production on 24th Sept '97 and then passed to engineering for homologation use (hopefully not crash testing!!).

    Currently mine is on axle stands while Im fitting Lotac Bilsteins (I didnt like my Nitrons and sold them to ChrisW for his 350) and a bigger brake master cylinder to go with the bigger brakes. I just wish Lotus would deliver the rear shocks so I can get the job finished....they have been on order since November!

    Its good to know that these cars are still around and being loved.


    Naughty Lust Blue. One of my fave colours. I bet that looks amazing on a Sunny day.

  9. Looks like the many perished hoses, gaskets and elbows that I replaced chasing down the high tickover would have solved it..... had I not also had a fiddle with the idle screw part way through replacing stuff.... I’ll get my coat.

    I know Barry, I know. NEVER TOUCH THE SCREW!!!

  10. Tick over has been tamed. Big thanks to sailorbob for giving me an afternoon of his valuable time to nail down the offending issue. Turns out it ‘may’ have been self inflicted while trying to chase down other niggles. Either way tickover is now playing ball again so a steady list of jobs can commence with the target to be a return to the road for the full April unwind. Just a quick spin round the block brought a huge smile to my face 👍

  11. Hi. Really interested in these. Can you confirm regarding the diamonds which go in the pod area. Are these to affix the very corners of the front bumper which if not used cause the front corners of the bumper to sag? 

    I removed and replaced the bumper getting a better alignment but the corners still look a little droopy and would like to get this sorted correctly come repaint time 👍

  12. With the Larini and sports cat its just too loud at the moment. I'm wanting to work with a standard exhaust to try and find a better (for me) solution. I have other toys that make your fillings rattle and your ears bleed. I would like the Esprit to be a little more refined than currently.
