Car is now running fine, except temp guage not working. Must have knocked wire off of sensor.
Scuttle came off easily once I knew what to do. Spent another 2hrs trying to fish out old sensor cable and run new one. Ended up cutting out the old one leaving the connector wedged in the oil lines by the filter. Ran the new one down the side by the exhaust manifold. Now that I know there aren't any other choices, I could do it in 15mins.
None of my new sensors exactly matched the old one. Put in the cheapest one first and it worked.
I was not amused being up to my waist under the first car after a roundabout with everyone flooring it out of the roundabout. Had the hazards on and a wheelie bin set out like a cone. When I did finish the battery was dead.
I will take some pictures for the scuttle guide and a crank sensor guide when I take the scuttle off to plug the temp sensor back in. Meanwhile it seems to idle better without it.
Oh, and Autovaux are useless lying sacks of cr@p. More later AFTER I get my refund from them.
