Running a little rich

[tgoodwin@xxxx]

Lately, I've noticed more of a fuel smell to my exhaust. It smells 
like it is definitely running rich. Also, when the engine is just 
warming up, I get severe hesitation. The only way I can describe it 
is that it feels exactly like if I was pumping the gas pedal as I 
accelerated. I think I have a bad fuel accumulator coupled with 
either a bad thermo-time switch or control pressure regulator. Any 
thoughts or am I completely off base?
