My 03 has a bad skip/surge around 3000 rpm's. It is most noticeable in 3rd gear at a medium to medium hard acceleration, matters not if it's hot or cold, but it does not do it every time. Generally, the turbo gauge will jump to nearly 0.1 MPa and then flutter up and down a couple of times when this skip occurs. Is anyone else experiencing this problem?
I've had it to the dealer three times already. They replaced the fuel pressure regulator and called it fixed. It still did it on the way home but not as bad. This week, the service manager had me try a brand new wrx w/ 9 miles on it. That one has the exact same skip also.
The gear does not make the difference. Third gear just does not accelerate as fast as first and second and does not put me into "radar hot zone" as fast as fourth or fifth.
