Just to make a change, I thought you lovely people may be able to help diagnose a running issue with my brand new (to me anyway) 3.9v8 with 127k miles and an LPG conversion (that i haven't been using - all of the following is based on running 95 Unleaded)
To start with, I found it was missing an air filter completely (empty air box), idleing high around 1200 and smelt like running it was rich. Also noticed a clicking from the driver footwell which sped up when accelerating.
Decided to do a service as lack of filter indicated it's not had the best of care. Put in an air filter, new HT leads, new genuine lucas rotor arm and dizzy cap, new plugs and oil change. Then engine started back firing, hesitating when trying to pull away and idling around 800 but going up and down like the moods of a manic depressive.
Indy mechanis suggested air mass sensor, so brand new one purchased and fitted. Idle is a stead 750 now, back firing gone but when cold really difficult to pull away without engine cutting out and through the rev range sounds quite rough still. Clicking noise from driver footwell is the main injector relay i've decided.
Will replacing the relay likely cure the problems, or is the fact that it is running at all mean the relay must be working even if it is noisey?
