new to this so here goes.
just bought a 2000 d2 V8 with an AG lpg conversion. after a couple of days it wouldn't run right on gas. felt like a rev limiter/ fueling at 2500rpm especially under load. next day petrol the same . changed airflow meter(this forum is great) and although much better ,but still not right.
I'm pretty sure its the coil packs / leads which i'm changing next week. Thats the royal we as the inlet manifold has a 30mm spacer to fit the lpg so you cant get to the coil packs. I spoke to the lpg guys who serviced it last and they remembered the car and said they had recommended that the adaptions were reset .Had this done and 17 faults logged , misfires causing emmissions / catalyst problems mainly plus maf fault and lambda faults. hence coil packs / lead changes next week (they are originals and the car has done 100k)
i'm worrried that the ecu is now learning from a misfiring engine and the faults will just reappear and stop the ecu fuelling properly. (to be fair its not a full on misfire , more of a hesitation when accelerating and a shudder at 50-60mph when torque converter locks and the engine is under load.)
the idea was to reset adaptions drive on petrol for 50-100miles and then get the lpg tuned.
do you think i'll need to reset again once i've had the packs done and will this affect the lpg (again)
any help would be appreciated especially if there is someone with a test book in the surrey / sussex area.
