9.5 AFR at idle. Cranking enrichment?

well i put two 220R resistors in parallel in the coolant temp sensor socket, didn't really change anything so I pulled the vacuum hose off the map sensor, NO change......! I pulled the carpet up in the passenger side to check the FCD wiring, hey presto, i prodded the FCD wiring and the afr's went back up to 14.5-15. I have removed it and cleaned up the wiring with proper solder joints and heatshrink. Idle is still down at 700rpm and a bit shitty but afr's are clean if a bit erratic.
