Hi Everyone
When the car was placed with JE they undertook the following:
Task 1 - The car had a problem in as much as the idle, whilst the vehicle was in motion, was about 1800rpm which caused a problem if I was trying
to negotiate traffic in a built up area as 1800 in second or third gear produced quite a speed, (the only way I could moderate the speed was to constantly dip the clutch). Once the car came to a halt, the idle dropped down to around 900rpm. The stepper motor was replaced but this did not resolve the problem so JE suggested that the problem was that the ECU was mapped for a 3.9 litre (not the 3.5 to which it was mated) and so was overfuelling at idle. I do not know what JE did to rectify the problem but the problem has now abated.
Task 2 - JE relocated the LPG ECU from the engine bay to the cabin.
Task 3 - JE supplied and fitted an enlarged plenum and 45mm trumpets and relocated the stepper motor from the bulkhead side of the plenum to the offside. (there are no obvious leaks on the plenum, AFM, vacuum pipes etc)
Task 4 - As the ignition circuit included a non Lucas coil and distributor, JE suggested that keeping the ignition set up as near to standard as possible would make the car more reliable and easier to diagnose faults in the future. They fitted a Lucas PRC6574 coil, an ADU7242L suppressor and a ERR4738 distributor.
All in all, this work cost me £2400 and as I said, the car was returned running like a dog on petrol and with very poor starting. It was returned to JE and they changed the timing to get the car running on petrol (to 10 degrees BTDC) but to my frustration, the poor starting remained.
Once warm , the car runs really well but during the warming up period, it is a little hesitant. Other than this problem the car runs really well and as it is serviced every 3000 miles or so I would say that for a 30 year old car it is in really good condition. There is a fuel pressure regulator fitted to the fuel rail (FSE FPG002) and fuel pressure is good.
I agree that JE should put it right and I am suprised that a company with such a great reputation is floundering a little. Like I said, I have every faith they will put it right eventually as they have a legal as well as a moral obligation to do so. I really do not like confrontation at all so I hope that JE do the right thing.
Regarding feedback from you all, I am very grateful and I dont want people falling out over it. It is only a car after all!!
I have written to JE and asked them what they propose to do. I guess I will have to wait and see if their reputation is justified.
Thanks again
