Re: Startup Hesitation



I had the in-tank pump replaced a couple of years ago. The main pump was
making a hell of a lot of noise and the engine kept cutting out in traffic,
or sometimes hesitating under acceleration.
That hasn't happened since - this problem seems to be more to do with how
many electrical items are in use, as turning things off restores idle
stability.
