  1. Gonzalo has gone Hollywood. Nice work Gonzo! Wayne
  2. Since it worked before being disturbed, I would vote for a short to ground (VE-) on the ECU pins 24 & 25. Seems strange that both outputs would get shorted at the same time, I suspect both wires are in the same bundle, however.

    ECU HELP!!!!

    No relays direct control by the ECU providing controlled ground to the solenoids.

    ECU HELP!!!!

    Hi Mike, Ah the British and their English. Sheet 5C of section ML of the service notes dated 15-09-97 calls out pin 84 to the purge solenoid and pin 85 to the can purge solenoid and the pin out list (per your posting calls pin 84 the vent solenoid and pin 85 the purge valve. I believe the pin out list is correct that pin 85 controls the purge valve. On this side of the pond the vent solenoid is called the close valve as it normally closes the canister to the atmosphere and only opens during the purge cycle. We Californians need to know this stuff!

    ECU HELP!!!!

    P0444 error is one of many "sanity Checks" to confirm continuity of the wiring. In this case the ECU is looking for +12 to appear on pin 84 when the ECU is NOT commanding the purge valve to actuate. Fuse B7 provides +12 to several places including the O2 heater relay, since you have no o2 heater error fuse B7 is probably Ok. You can check each side of the purge control valve with a meter (with key on not started) and +12 should be there on both sides. If not the + 12 is not being supplied by fuse B7 or the purge control valve is open or the wire to B7 is. If +12 is there on both sides then there is an open wire to pin 84 (not 85) of the ECU or the ECU has a problem. There are two solenoids for the evap. system. One is a atmosphere close valve (pin 85) and the other is a purge valve (pin 84) which opens to connect the canister to the engine vacuum. P0444 is all about the purge valve pin 84. The purge valve is NOT documented in the Lotus service manual but it is in the parts diagram page 44.05a as item 10 and the close valve is item 7. You don't want to know why I know all this stuff!
  6. This is tough to find. The secondary injectors could be dripping if they were not replaced at the same time as the primary injectors. If it is consistently doing the popping at idle you could temporarily remove the CATs (generates an error code) and see if the popping stops. If it does that would be a strong indication that excess fuel is being touched off in the CAT.
  7. Hi Mike,


    I see you are posting again on the forum.  The forum has not forgotten you! 


    Hope all is well, Wayne

  8. Sorry for the delay. There must be something else going on. The post CAT sensor's only function is to let the ECU know how the CATs are functioning, they don't control anything. A misfire is being caused by some condition (fuel mixture, or timing,) and the post sensors are re-acting to it. Maybe very rich mixture finding its way into the CAT and being lit off by the heat in the CAT??
  9. Yes, you need a few special tools and a tool to tune the belts to the right frequency. First you need to buy the service manual which contains all the information you need. However, then the tools, be advised this is a high risk job. If you should make a mistake you could bend many valves. Many "Lotus Shops" have done it wrong and caused much damage. Find someone in your area who has done it or paid to have it done and hook up!
  10. I would not use a locking strut, it forces one side to take the load if the tailgate is opened for a long time, and results in bending the hinge plate. Replace both with standard lifting shocks with the right pressure and length.
  11. Dave are you actually watching the o2 sensor switching times and voltage levels. what are you using to "watch " the o2 sensors?
  12. The parts have been sold, thanks everybody.
  13. Everybody must go look at the photobucket pictures, this is a beautiful engineering job. Did the intercoolers fit in the Cortina??
  14. I have a new, still in the shrink wrap, Holloway upgrade kit for the UN-1 transmission and a new custom high torque twin disk clutch built by AP still in box. I had intended to add these to my modified V8, but have moved on. I have the clutch dyno curves from AP. Only two clutches were built by AP for myself and Mike Sekinger, when we built our Esprits. The Holloway kit is $4,000 and the clutch is $1,300 or $5,000 for both, plus shipping. I apologize for placing the AD here, but I could not log into the parts for sale section, sorry.
  15. Is there no work order/estimate with the details of why the timing belts were "recommended" to be changed? Normally this is the case. That would be the smoking gun, if the belts were recommended to be changed based on time or mileage only. I assume that the owners attorney is advising you on how to present your expert opinion. Experts are experts based on their experience and resume, I have not heard of this level of technical bonafide being required.
