  1. Have you checked the wastegate solenoid is (still) working? Without that in theory max boost should be 0.65bar if the actuator is correctly set. Does the car still have a cat fitted? Might be worth checking it's innards haven't disintegrated. I lost all boost on my S4s last week and it turned out to be a blocked cat. P.s. if the gear shift is indirect it might be time to renew the translator bearings and joints on the gearbox end of the shift cables, assuming they haven't already been done recently. Renewing them transformed the gearshift on mine.
  2. Spotted it driving past Gadebridge Park in Hemel early this afternoon. Think it was a lime green colour, as best I could tell through my tinted sunnies while walkibg through the park.
  3. Well that drive was... errr... exciting. Car is running fine again; no misfire and boost all accounted for and then some. You were right about it being more lively @cweeden! Seems the cat was already partially blocked for some time before the exhaust was done because my adjustments of the wastegate actuator are now well off. I was seeing 0.91bar of boost on only ~50% throttle, so I think I need to back out my previous adjustments 😆
  4. Not too far from me, but sadly I'm otherwise engaged tomorrow.
  5. There is a stretch of the M25 around Potters Bar/Waltham cross that is surfaced in concrete and it's a bit rough - or at least it feels like it in an Esprit - and it was around there that I was first aware I'd lost boost as I pulled out to overtake a car on one of the uphill stretches. My best guess is the rough surface was enough to shake an already fragile chunk of the cat innards free and block the exhaust. Indeed. I'm hoping all the time I spent before it went in for the exhaust trying to set the actuator wasn't wasted and have to go through all that again 🙄 I'll prepare for a possible while knuckle ride when I enter the national speed limit road for the first time later.
  6. Hoping that wont be needed now based on the MAP pipe discovery. But we'll see after a run out later this evening to test.
  7. Well done Dr @Bibs, diagnosed it in one. The pipe from the MAP sensor had been pulled off the barb on the engine and was found dangling down in the engine bay. Must have got distubed by accident while they were working in there. I plugged it back in and immediately the car is running so much better. I haven't properly driven it yet, but just based on driving it in and out of the garage the throttle response and idle is much improved 😌
  8. Thanks @Bibs. I'll take a quick look at the MAP pipework today. They did some other work for me on the car (photos to follow another day) and could well have disturbed that thin tube in the process, so it could be that.
  9. Bit of a mixed bag of emotions for my 500th post on my restoration thread. Car was booked in for a new exhaust to be made by Hayward & Scott back earlier in the year and was dropped off to them a week ago last Saturday , however on my way round the northern stretch of the M25 to drop the car off I suddenly lost all boost . The car wasn't misfiring and no CEL light was observed, I simply had zero boost. I managed to get the car there safely without any further drama, because its still otherwise driving fine and able to keep up with the traffic. We couldn't find any obvious reason for the loss of boost for the brief period I had to look at it when I dropped it off; hoses all looked okay, wastegate flap moves freely, the elephant trunk hose from the airbox hadn't delaminated and collapsed, so I was at a bit of a loss. Fast forward to today. I collected the car and while loading the old exhaust parts into to wife's car several large chunks fell out of the old cat, so at that point we thought it might be a simple case of blocked exhaust and apt timing for a new exhaust. Anyway, here are a few snaps. I've had a 3" system made with twin 3.5" inward rolled slash cut tailpipes and a 200 cell sports cat. On the way home sadly the car still wasn't running right. The boost seems to have returned to some extent, but if I try to apply more than the merest amount of throttle it just starts coughing and spluttering, but oddly still no CEL light. As with the journey to Essex, the car was able to be driven back safely, but just seems to have lost its get up and go. As I backed the car into the garage when I got back the CEL light did then come on, so I'm hoping whatever error code has triggered that may reveal the problem. Either way I'll be investigating more thoroughly over the weekend. Here is a brief video of what it sounds like with the sports cat fitted. I did get a decat made too, but that's currently sat in the boot. The small puffs of black smoke suggest I have a potential fueling issue, so I'm hoping that the new RC injectors I have may go some, if not all the way to solving the running issues 🤞
  10. That temperature sensor isn't present from the factory on the S4s @fjmuurling. What you can see in the photo is the end arrangement I created so I could install the temperature gauge in my car. The CAI instruments in the S4s have a separate low pressure switch and sensor, unlike the earlier S4 which is a combined unit. Lotus dropped the oil temperature sensor (and gauge) on the S4s and replaced it with the separate low pressure switch (a backwards step if you ask me). To reinstate the oil temperature sensor, I installed that T-piece you can see there so I could move the low oil pressure switch to make way for the oil temperature sensor to go where it would normally be located on the S4.
  11. I don't know if the GT3 is different, but I had to fit a T-piece on my S4s so I could add the deleted oil temperature gauge back to mine. This is it with the incorrect taller pressure sensor that was originally fitted to the car by the previous owner. It's snug, but it does fit. There is much more clearance with the correct sensor can fitted however.
  12. At my first/last MOT with mine the tester pointed out that my numberplate lights were working but very dim. When I took them off to replace the bulbs both lenses cracked upon removal. I ended up replacing mine with a pair of these @Sparky The opening in numberplate plinth needed opening up a touch with the dremel to get it to fit, but the hole centres were the same as the original unobtanium parts from the factory.
  13. Was spotted middle of last week by my Father. Was on an R-plate.
  14. Youre in luck @agk, I have one complete set left. Bumper bracket set only will cost £218.40 + P&P Bumper bracket plus the two plates in the wheel arch for the fuel tank boards (A082U4680K) will cost £235.20 + P&P Postage and packaging costs £13.50 in both cases and will be via RM Special Delivery to get sufficient insurance. If you're outside the UK I'll have to get some prices for couriers. Collection is also welcome if you're near Buckinghamshire.
