too rich on tick over when hot too..

[zen]

Please see other post about too rich on cold start up.

So...i hardy ever run on petrol when warm i use propane.but was wondering if injectors were playing up ie sticking due to lack of use so gave her a good run on petrol..discovered that she is running far too rich..espically on tickover but on power as well..
Now fuel pressure is ok..NO FAULT CODES..temp senser i assume is ok as ramps down tickover when hot...lamda are ok i assume as when on gas i ger 14,7showing on wideband a/f meter.but only one lamda connected to lpg/propane ecu so can pnly see that one working on diag programme...
Also far far too rich on cold start up..

Efi temp sender playing up??

14.7 on LPG is stoich for petrol, but not LPG. I think stoich for LPG is 15.5.
