Has anyone mentioned the condition of the earth strap / bolt to the bodywork? Also have you checked the condition of the wires on the plug that goes into the ECU?

 

Update - Injectors tested and cleaned, results as per below;

Before Cleaning

Inj 1 - 90
Inj 2 - 91
Inj 3 - 84 (Spray pattern listed as Fair)
Inj 4 - 90

After Cleaning

Inj 1 - 94
Inj 2 - 94
Inj 3 - 93
Inj 4 - 94

I don't know too much about what figures would contribute to a misfire but it's obvious that 3 was slightly down spray wise.

I've only driven it back but it certainly feels more responsive, not lumpy at idle though not idling at 1k solid like it used to, more one line under. Have since pulled the ECU and let it relearn the idle, still smooth and no puffing exhaust - not getting my hopes up yet, I'll use in anger over a few trips so keep your fingers crossed for me!

 

It shouldn't idle at 1k...mine sits rock steady at 900 with the fan on

 

Which sounds good

 

I also bought one can of BGK 44 to use it in my tank since a lot of members here are proposing it. Does anybody know if once i open the can i have to use the whole liquid or i can put half of it in one bottle and use it in like 6 months? I am asking because the liquid comes in a tin can and i do not know if it will be useless in 6 months time after opening the tin. The instructions says that one tin is good for 75 litres of fuel and i do not want to use it all since it is not available here in Greece and i had hard time to buy it from UK
