You have nailed it on the head stu mate thankyou so much haven't checked yet as cars stored away at the moment but I had a funny feeling it came out of the injector end bit and I will get searching next time I'm down there, I only found all this out when I looked under the car months ago to see there was no knock sensor wire, then took the speedo cluster out only to notice there was never a bulb for the engine management light, (there is now, as I do everything how it should) funny thing was the car always ran good but thankyou stu for your help and you dan mate 👍
