  2. I have reset the ECU and drove 20 minutes to (hopefully) reprogram the logic. I will go for a spirited run this weekend (great weather ahead for Ottawa) and report back. Thank you everyone to date with your suggestions. I will take this one step at a time. Cheers.
  3. Thank you for these suggestions. I will start by resetting the ECU idle logic using the process described. If unsuccessful, the IAC may need further investigation. I will report back with results. Much appreciated.
  4. During regular driving, my 2003 Esprit runs fine, idling around 900 RPM. If I accelerate quickly through a couple of gears, the car sits at high idle around 2600-3000 RPM. The only way I have found to "fix" this high idle problem is to pull over, turn off the motor and briefly disconnect the battery. Everything is back to normal when restarted. I see some similarities to this problem across the forum but nothing specific to this situation. There is no CEL and my code reader shows no error messages. Any ideas out there? Much appreciated.
  5. Thank you for your reply. Very kind of you. The local dealer FINALLY got their stock after 3 weeks so I do not need the hose. I think I will finally overcome my Lotus withdrawal. I am looking for a few other items such as a muffler for a US 2003 (centre dual exhaust). Larani is asking $1650 for new.
  6. Parts arrived. Car will be discharged from sick bay in 2 days. Finally.
  7. Hi All - After analysis for a 2003 Esprit high revving idling engine, the following hose needs replacement to fix the problem (I hope): I am looking for either a source or clone part for the following..... Hose IAC to Compressor Duct part number A918E0186Z (quantity 1) O-Ring 2.62mm x 7.59mm part number A918E6070F (quantity 3) Can anyone suggest a supplier that will/might have these in stock? Thus far, I have only discovered suppliers such as Lotus Garage that identify the parts on factory order or backorder. My Montreal Lotus dealer is trying to find the part too with no luck to date. If I can get these parts in my possession, I can get my toy back on the road. If you have any ideas, please share... I am having Lotus withdrawal. Much appreciated Ian in Ottawa

  9. I just ordered a OBDII reader. Hopefully it will arrive quickly. I'll stand by until I have more facts. This means of course no driving for now.
  10. Hi Pete - Great link. The photos are worth more than 1000 words. Yes, the hose is actually blue silicon as in the photos at the link. I read a variety of related posts and gently tapped the top of the plenum above the IAC as a temporary fix. This kept the RPMs to about 1950 but they seemed to want to go higher. Also, the CEL is on for the first time since the high revs situation occurred. I will take the plunge and order the plenum gasket and the IAC (Bosch PN 0 280 40 516) for the big plenum removal project. Do you recommend also replacing the Throttle Position Sensor and blue vacuum hoses during the dissection? - Ian
  11. Hi Paul - I have checked the throttle linkages and cable. The linkages are fine with appropriate movement. The cable has about 1/4 inch slack. This may be excessive but certainly not the source of the high RPM problem. I think I see the transparent IAC hose which has blue nylon tape wrapped around the front (exposed elbow) so that tape in itself may be an indicator of a previous owner's "repair". I will follow the hose that is visible along its complete functional route (via non-return/canister purge, charcol canister and canister close valve and filter). Removing the plenum to replace the hose appears to be a sensitive/long project and I may wish to go to the nearest Lotus dealer ($$ ouch) in Montreal about 2 hours away. I did try resetting the EGR valve but actually disconnected the positive battery connection instead of the ground connection. Would this make any difference? All power was off throughout the car when I disconnected the positive connection. After reconnecting the battery cable, the car started up cold at about 1400 RPM and by the time I was out of the driveway, the RPMs were over 2300. Less than a minute later the RPMs were over 3000 and after a 20 minute drive on the highway in 5th gear, the RPMs were hovering just over 4000 in neutral. It is beginning to seem like either a vacuum hose problem or perhaps even a Throttle Position sensor problem, as the literature indicates a "limping home" capacity at high RPMs to compensate for a faulty Throttle Position sensor. As I do not have a Type 1 scanner tool, I may swap the TP sensor with a new one as a troubleshooting step. Will keep you posted. Thank you. - Ian
  12. Thank you for the wealth of information. There seems to be a little slack in the cable at the pedal so I was originally thinking that the cable or throttle linkages were gummed up along the cable run or near the engine. I'll check that first and then go through the series of suggestions you have offered. I'll report back with my progress. Thank you again.
  13. I have a 2003 Esprit and normally it idles around 1100 (very nice, except with A/C running it sometimes drops to 600 and stalls). However, I have run it once or twice for quick acceleration and now the throttle seems to be stuck at idle around 3500 (sometimes as high as 4200 temporarily). This car was a garage queen originally and I was thinking that either a linkage or spring may need lubrication/adjustment attention. It may be something more ominous (read: expensive) but I am a newbie Esprit owner and would prefer to repair the solution on my own if possible... TPMS was recalibrated in March 2010. Throttle was adjusted in June 2010. Any hints or experience out there that can be shared to troubleshoot and resolve this issue? Thank you. Ian in Ottawa
  14. Hi Mike - Thank you for the welcoming note. I also needed to take the Esprit to Canadian Tire for the federal inspection. The only thing the technician checked was the daytime running lights. As was the case for you, the inspection was less than 5 minutes. The car is a blast to drive though a little too loud for my better half. Need to find an appropriate muffler solution (running straight cats right now). Cheers, Ian
  15. Thank you for all your replies. I checked with Gentry Lanes (the Toronto Lotus dealership: good support by phone, emails go unanswered) and they confirmed that no 2003 Lotus Esprit cars were sold in Canada with a clutch switch. Additionally, they checked their parts reference database and no clutch switch was ever installed in the 03 Esprit. So, no original parts were ever manufacturered. I have no issues driving without a clutch switch. It's second nature to take the car out of gear before starting. I'll need to aftermarket a solution. Not a complicated project, but it is all in a tight space and would have been nice to avoid the task altogether. Cheers.
