Just a small update, haven't really had time to do much to the car recently as I am so busy at work, getting home at 9-10 most nights. Also its been freezing in the garage.
I have managed to fix a small water leak, the only non samco hose in the engine bay had a tiny split in it, I had a spare piece of Samco so put that in and topped up with antifreeze.
Also, connected my laptop into the kstar unit (after getting the password off Vince at Stealth) and found that all the values were zero, luckily I had a backup of the original map so I wrote that back in. The engine was running and the note and idle improved immediately. This is probably due to the fact that the timing is retarded about 6 degrees on the distributor and this is compensated with the kstar.
Got a small problem with the idle, the control valve isn't buzzing so it isn't idleing that well.
Ordered and received the three sensors on the side of the head to try and also got another idle control unit to try. If anyone has any tips on troubleshooting the idle control circuit then they would be appreciated. I am hoping to have a look at this tomorrow.
Does anyone know if an 8v Idle control valve is the same as the 16v? I'm pretty sure I have at least one 8v one I could try.
