New MAF and power loss

Last week my MAF failed completely on my 02 Spec V, I ordered a new one and installed it, reset the ECU and performed the idle re-learn procedure. Since the new MAF, the car runs fine when it is cold. when the car gets warm it loses power, idles very low (4-500 RPMs) with an occasional stall and it will not rev past 5500 RPMs. Could this be that the new MAF is faulty or something else?

Have you tried regrounding the MAF? Has done wonders for other models...
