My Zavoli unit (Multipoint sequential) was serviced last month with two filters replaced. Now the vap. unit is mounted vertically... Avon Autogas assure me that although unorthodox, it should NOT affect the operation. So, everythings running nicely etc. even engine light has switched off! I still have the same problem that on an incline with power applied in high gear, it will misfire a little, but dropping down a gear sorts it before any dramas!
Now last week it took a long time after startup to switch over to gas. When it eventually did, the revs/power dropped and then rose again and the engine light came on. No other dramas but its stayed like this, switching over a little slower on a cold startup but working fine...
Took it for it's first long motorway journey yesterday and after about an hour of Cruise Control 75-80mph driving it started stuttering. At a certain point (and always on an incline) with power applied, the revs/power will suddenly die and you can hear a "ticking" coming from under the bonnet where the vaporiser unit is. No other misfire/backfire noises, but more power equals dropped revs....Coming off the motorway the engine dies and we coasted and took a bit of starting but did restart. Please note, it runs smoothly on petrol. Now today the same is happening all the time and it sounds like its running on 1 less cylinder... Switch over to gas- revs drop- ticking noise. select petrol, off we go...
Are we looking at new injectors or could this be a sparking issue?? (can it only affect gas and not petrol?)
Any thoughts before it goes into Avon AutoGas this week...?
