Oldsmobile LSS Supercharged Problem at High Rev !
 

Hi !

I Have a Strange Problem, and I saw some of the 3800 Supercharged Owner Got too ! Between 4500 and 6000 RPM the car, is rushing to get to 6000, like if it was getting too much gaz ou poor fire ! I know the past owner of my Oldsmobile put 500 bucks to find the problem and nothing, I talked with a guy and he tried those part's : Crank Sensor, Maf, Spark Plugs, Coil Pack & Gaz Filter ! He didn't paid cause he's working in a Garage and was trying part's to check if there was a change ! He did'nt check for Cam Sensor and Spark Plug Wires But Mine are New so Not the problem ! I Checked the Bypass Valve on the Supercharge and is Working Properly ! The Guy is gonna change the PCM to check if there's a difference ! So you guys, do you have any Idea or is anybody got that problem before and fixed it up ?

Thank You !

Only other thing I can think of from your description would be to check the TPS sensor with a multimeter. A better descripion of the problem may help as well.

All I got from it was the engine seems to be "rushing" to go from 4500 to 6000. Does this mean it's bogging, revving freely or can't rev?
