  1. Hi Clive

    and our SWMBOs

     

    On our way to get the ferry from Plymouth later today

     

    What a stonking day it was

     

    Hope you had a good Blat too

  2. It's easier to press on if you take the ball joint off the car and press on with a socket and vice. Very tricky to get on square whist still on the car.

     

    Just slightly loosen the locking nut and then count the turns needed to remove the joint from the wishbone so as not to change the geometry when you replace it.

    I did this on my old car. The wiring is complicated to explain in writing but I used the positive that originally goes to the fan switch to go to both the switched pole (pin 30) on the relay and the "coil" input (pin 85) on the relay. The output of the coil (pin 86) goes separately to a switch and also to the radiator mounted temp switch so that when either are closed they are earthed and the coil is energised. The output of the relay (pin 87) goes to the positive on the fan.

     

    If you're at MADS I can do a diagram

  4. I believe the QR1118S ball joint from a Fiat is used when converting the single link to a De Dion upper wishbone to attach to the original "trunnion" upright on a live axle.

     

    The taper is different on the De Dion upright with the spherical joint lower wishbone.

     

    DO NOT USE A QR1118S with The De Dion upright

     

    The correct ball joint is QR1798

  5. Firstly a big thanks to Nick Chan for advice and loan of the CAN-USB adapter and a spare Lambda Sensor.

     

    Problem - Did a test day at Curborough with LADS last Wednesday all went well until the drive home. After about 10 miles the car started to hesitate ad then surge on light throttle, mid to full throttle no problem at all. Stopped for fuel approx 15-20mins then same again, OK for 10 miles then very difficult to drive on light throtted. To cut along story / trip home short the pattern was repeated again on the final leg home. The last 15 miles on the motorway driven by accelerating to 80 then off the throttle to 65 then accelerating again. The car would not cruise with the throttle in a steady position.

    A visual check revealed no loose connectors / TPS / split MAP sensor pipe.

     

    Diagnosis - Ran car with Easimap on Laptop and it revealed no change in the Lambda reading - was giving 1.12 constantly. Previous research suggested that it should oscillate.

     

    Cure - Replaced Lambda Sensor - Car now behaves as it should, no hesitancy etc, Easimap shows the Lambda output oscillating between 0.6 an 1.0.

     

    Lambda Sensor cross reference is

    # BOSCH : 0258 006 155 - 0258 006 156 - 0258 006 484 - 0258 006 485

    # FORD : 1215538 - 98 AB 9F472 BB - 98 FB 9F472 CA - 98 FB-9F472-DA - 1143514 - 2S6A-9F472-BB - 1053108 - 1067580 - 1088851

    # MAZDA : 1 E04 18 861

    # NGK : OZA519-D1 - 0244

    # NTK (NGK-GROUP) : 0383 - OZA659-EE9

    # VW : 7M0 906 265 B - 7M5 906 265 D - 7M5 906 265 B

     

    Maybe of help in the future
