Hi,
This problem has been bugging me for ages. I have a 1.8 CVH that exhibits a misfire problem and high load conditions at low revs. (E,g pulling up a steep hill in second, or even just flooring it in third with the engine at about 1500 rpm). It's like the advance is way off - but of course there is no manual adjustment of the advance. Releaseing the throttle and reapplying sometimes clears the problem and when she picks up she flys (as best a 1.8 CVH can fly!)
I have bypased the fuel seperator, chnaged the ECS module and crank sensor (albiet with second hand parts), checked it over on some crypton tunning kit (which checks out fine), even changed the fuel pump push rod.
Anyone have any ideas?
The car has inetermitantly died on us a few time in the past as though all electrics went, only to be able to start some 10 minutes later, but this hasn't happened for a while - possibly through one on the changes mentioned above.
