Acceleration Faltering, Details 2nd page Options

[Tigawoods]

lets cut to the chase.

-car ran fine after cam install

-small valve tap

-after 2 weeks small knocking noise that seems to be coming from below the cam gear and only sounds when its around 1000rpm

-had an exhaust problem - detached the midpipe to run open downpipe until i got it fixed

-car ran super lean at low rpms under a fair load and sputtered as if its grasping to find power. sputters from stop to go at low rpms and drops super lean

-new mid pipe welded on

-car still sputters from stop to go at low rpms but now it gets a bit rich or just sputters with an even 14.X A/F r

- AND at 4900rpm under 100% throttle the car falls on its face and looses power. if anything under 100% throttle there is no problem.



i have a race this sat. and sun. i really need to figure out if this is a tune problem or an internal problem.
any insight at all will be helpful! thanks!
