car wont rev past 4500 rpm(help)

[steve33]

Hi There,
just picked up my new 97 wrx recently and there are a few little things on it that need sorting,was wondering if anyone here had similar faults/experiences,
To start off the speedo is'nt workin,when the car reaches 2500rpm it judders then it pulls tru to 4500 and then its like the rev limiter is kicking in,,,
We changed the mass air flow sensor,still the same,Also it seems to be using a lot of fuel,, Any Help on this would be appreciated,,,,,,
Thx

is the speedo doesn't worjk then it will go into limp mode and limit the revs to 4500 as you are experiencing....................
