I've already posted this question on 2 other forums so ill give this one a try for technical advice.
Ok after recieving my Boxster from the bodyshop, I immediatly noticed that the acceleration was lacking BIG TIME. So i figure since it wasnt drivin in 1 month I filled the tank up with gas and drove it abit and that seemed to clear up the low-mid RPM lack in power... However, the High RPMs (5k & Up) power curve seems to flat line.
Usually when that happens, I clean the MAF and problem solved but this time it didnt work, I also cleaned the airfilter and no change.
Yesterday morning I did notice that when the engine is cold, the mid-high rpm acceleration is non-existant until the engine warms up for about 30 seconds later, then the mid RPM power is there again... but still no power past 5k RPM's.
Anyone have any insite with this issue?
