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!

did a bit of searching and found somewhat similar stories. others suggested that it could be fuel filter problem. IAC valve problem, or an o2 sensor problem.
mainly from this thread http://www.6gc.net/forums/index.php?showto...4187&hl=TPS now his car was running lean more so than mine is. mine isnt running lean TOO much at all but it is still running lean. only from stop to start and at low rpm under load -------------------- 1995 GT::::Diffusing the Situation エキサイティングカーレーシングチーム! march 2010 COTM : 6GC feature 2014 : january 2015-2016-2018 COTM |
