ACCELERATION LAG FROM 1500-2000 RPMS

2002 Suzuki Aerio • 202,000 miles

Car specs: 2002 Suzuki Aerio SX hatchback 5 speed Manuel

When accelerating from a stop I notice that from 1500 to 2000 rpms the acceleration slows, not completely but its almost like you let off the gas almost all the way, then apon reaching 2000 rpms it continues acceleration normally, it does this in every gear, most noticeable in 3rd and 4th. I know that the air condition can cause a little lack of power but this happens even with AC off. This is intermittent and normally happens after driving for 10 mins and can last 5 mins to 30 mins. The only problem with the car is the clutch is going bad and needs to be replaced soon.

Have you checked fuel pump pressure?
