with reference to my previous post (wont start) just had a new fuel [pump fitted (after market) car now runs badly, ok on the flat, but come to a hill just got no go, wont kickdown like it did before, (automatic) feels like a large giant has hold of the rear bumper, floor the pedal and it nearly stops, spent a load of money a few months ago, erg and all the other sensors and it was running superbly, could the fitting of the new pump cause all this mayhem? there is no engine management light on when this is happening
