No power under 3000rpm
Repost w/all different info
Problem! All opinions will be appreciated.
2002 S2K Vortech supercharged with intercooler & up-graded fuel pump --47000 miles
I shut it off it was running great - the next time I started up I have no powerbelow 3000 RPM.
I have to get the RPMs above 3000 and ride the clutch to get going.
Seems like it's starving for air, A/F gauge tops out all the time.
On the freeway it seems to be fair - except the air fuel/ratio gauge is going nuts.
Have had four people look for vacuum leaks.
Sprayed Carbcleaner all around Idle never changed.
Disconnectedthe catalytic converter, no change.
Disconnected the air cleaner box, no change.
Disconnectedthe intercooler from the intake, no change
Sprayed carbcleaner in the intake rpm's actually dropped.
New; MAPsensor, no change
New; plugs
checked the fuel pressure no problem.
I would appreciate all your thoughts.

Codes that were saved, CEL went off by itself & has stayed off.
After thefollowing codes were wiped by a previous mechanic, then…my friend hooked up hisOBDll. Said my oxygen sensor kept opening & closing.
I think, Imight have a supercharger idler pulley going bad. You think that could createenough drag on the crank?
