Called shop and explained that sometimes at a low rpm, w/ steady foot on the gas, the car is "bucking", like I'm quickly pumping throttle. They told me it sounds like my low pressure regulator. That an easy DIY to replace??

 

i've never even heard of this .. you sure are having you challenges this month aren't you ?

 

I've never heard the term either. You have a pressure regulator and a damper-both easy to test.

 

Right you are ice! haha

What tests you referring to?
