G,day . curly little problem with my EA Spac 5 speed wagon, idles is fine power is fine put ya foot down under load no probs there , the problem is when i back of the on the pedal and have the throttle just cracked open a little bit like when cruising along a flat road or when going down hill and i back off the throttle but not completely it misses coughs f@rt and can get bad enough to give a mild case of whiplash to everyone in the car , also in first gear at about 2500 to 3000 revs going up our drive ( very rough dirt track up hill for half a kilometer ) it surges as if it were about to run out of fuel . did the easy things first plugs air filter bottle of injector cleaner , ask at guy at a carby place if he thought the injectors could be the prob he thinks not , he suggested the TPS , anyone got any thoughts on what may be the problem, thanks in advance for any input.
