Q: Car hesitates when press gas after stopping on 2005 Pontiac Montana

Hi there. Recently, I have found that my 2005 Pontiac Montana SV6 hesitates after I'm stopped at a light or stop sign. Once I start accelerating, it feels as though the van doesn't want to go anywhere, and then all of a sudden kicks in. When I was at a quarter tank, the car actually stopped completely. I would push the gas all the way, and it wouldn't go anywhere, and then it shut off. Then when I finally got it started again, it didn't stop anymore, but it still hesitated. What could be causing this problem. Please advise. Thank you.

Had similar problem and it turns out the fuel regulator was leaking, causing reduction in pressure. I couldn't find a leak because the gas was dripping onto the engine and evaporating, according to the mechanic. Mechanic said it was a fairly common problem, so you might want to check it out. It's a $40 or $50 part but a couple hundred bucks labor for the mechanic, he claims it's tough to get to.
My montana does the same thing. It has since I purchased it new. The dealership said the transmission had to have time to work out since it was new. Now I am getting a check engine light. I hooked the computer code reader to the car and it says its the camshaft sensor position A circuit malfunction. See my question above about camshaft sensor.
well your mechanic lied to you. it only takes 15 minutes to change i did my own fuel regulator. it wasn't that hard to do
