SUBARU ENGINE PROBLEM>>NEW USER
hi there im new to scoobynet and i have recently purchased a MY99V subaru impreza 2.0 sport awd last week but have developed a problem a few days ago.
Problem:
when taking off the car jerks as if the mixture is incorrect but once it takes off it is fine
i have changed the spark plugs, fuel filter , ht's and oil
I get the 'check engine' light once every now and then, im not sure if this is a common fault or not as its my first subaru can anyone please suggest/point to the right direction to what i need doing
Thanks

Ah you answered your own question, cold air induction kit, sounds very likely to be your main problem.....
Maf sensor should be located in the induction kit pipework.

Also, on 98-00 cars the hotwire MAF sensor is very delicate and induction kits are known to kill them through either excessive vibration or oil contamination. If possible, remove the I/K and refit an OE intake set-up with box and panel filter. Trust me, the I/K isn't giving you any more power anyway, so you might as well try to regain reliability.

Phase 2 Sport (MY99+) doesn't have a MAF. Just a MAP sensor which IIRC is located on top of the inlet manifold.
If you're getting the CEL then there should be some codes recorded, get them read (or plug in the green connectors under the dash). Could be something as simple as the lambda sensor or a dodgy connection somewhere.

Could be that you've temporarily masked or fixed the problem by flushing the injectors or running higher octane petrol, but the likelihood is that your engine is suffering an intermittent fault and still is, notwithstanding the current cessation of symptoms.
You'd be well advised to follow [-(o)-]'s suggestion, and read off any fault codes stored in the ECU. These should, in the case of any eventual recurrence, help you pin down the problem.

Sheesh that's a bit of a stylistic "experiment". Phase 1 vents on a phase 2 bonnet, and an STi8 scoop, all on an N/A car. It'll be quicker if you pull all that stuff off, assuming it's just been stuck on.
As to the fault code reader/Select Monitor, difficult for anyone "local to you" to answer that one given that you haven't told us where you are. However, you shouldn't need one. If the MY99 normally aspirated ECUs have the same diagnostic feature set as the turbo ones, you should be able to read any stored fault codes direct off the check engine light by linking the read memory jumpers under the dash. A click of the search button should tell you all you need to know.

Plenty of options round that neck of the woods, but don't discount the DIY option. This is no more or less complicated than connecting two plugs, turning the ignition on, counting a sequence of light flashes off the CEL, switching off and unplugging the plugs. Likely to be a lot cheaper than paying someone to diagnose it for you.
