Sorry for the seperate post here, but looks like more people surfing around this forum. Mechanical experience may be what I need.

Thanks

 

try a 3 part fuel injection cleaning system. valvoline has a good one but it its about 70 bucks at the store. Then try the fuel filter and at the worst a fuel pump

 

sounds more like a surging issue than a fuel injection issues although I could be wrong. Check the vac lines, mainly the unes around the n75/wastegate area, and the one coming off the front of the manifold

 

If she is breaking down it has to be either fuel problem or Spark
does it kinda like fall flat on her face ?
like lose power then pick up ?
you can try and load up the engine and feel if she
does it I need more infor on the problem
ButI would be looking at the M.A.F. and Spark before anything els

 

Ok, thanks for the replies so far. When I get back to the car this weekend I will try to get better data. RPM range where the problem exist seems limited to 1500 to 3000. Its not what I would call a loss of power, it more like several slight hesitations in a row.. very quick, and then smooths out again as the RPMs go above 3K. What else should I look for to tell you? I will check (maybe replace) the spark plugs too.

Thanks again.

 

I am having the exact same problem, I see this was posted a year ago, have you solved the problem?
