Looking at the ecu codes the one that was fitted was from a 4.0 and the other one that I tried is 3.9 I must admit the 3.9 did smell a little less fumey but not had the chance to take it out on the road to test it properly. Compression seems ok...

The ecu is standard to my knowledge but I haven’t opened it up to check the chip, I’ve played about with the timing and it seems best at around 6-8deg btdc. Plugs are standard Ngk BP6ES

Was kind of hoping that a smoke test would find something simple like that but no the hoses are fine. I’ve checked them individually as well. Also got hold of another ecu to compare and still have the same rough idle although not taken it out on...

From the air intake in the plenum with the butterfly open

Just tried that and It holds vac. Tomorrow I will try another distributor to eliminate that, it’s very strange! I’m starting to lose patience with the thing lol

Hi it’s running non cat map and no lambada it’s Hotwire maf setup. I have sucked on the advance pipe and I can see it advancing with a timing light.

The pipes are good and the distributor is a new powerspark unit so maybe it’s faulty, I still have the old one so will put that one back in just to check

It’s Hotwire efi power seems to be good through the rev range. I’m baffled why it’s leaking from there?

I’ve been having rough running at idle and smells quite rich, it has power through the range it just misfires at idle and plugs are black wet and oily. Done a vacuum leak smoke test that the only place it leaks is from under the distributor cap...
