Re: Acceleration Problem

I don't know if my problem is the same but it takes a while it the it to start up and when it does it spudders a bit some like a v6 rather than a v8 and acceleration is not the same it will slow down then drive normal but with the exhaust spudders, I open the hood no noises coming from motor idles fine what you guys think it could be

Re: Acceleration Problem

Low fuel pressure? I would start changing the fuel filter/regulator or if you have a fuel pressure indicator, measure the pressure at the right fuel rail (seen from drivers seat) You could do a quick check and push the schrader valve on the right fuel rail after priming once (no start and engine cold, to prevent a fire), the fuel should come out under a high pressure.
