Check Engine warning light
 

Hi new to this Forum. Can anyone help me regarding the CHECK ENGINE warning light coming on on dashboard. Tried a Diagnostic check at my local mechanic but it would not register. How do i get it to go off and what could be the problem. Engine sounds like it is slightly missing on acceleration.
Thanks.

Hi :)

What model and year of car?
Any modifcations?

Ta :)

Hi it,s a Impreza Turbo 4x4 1999. No Modifications and 110k on the clock

Well could be a few things, common issue is the MAF on the MY99/00 cars, I would suggest not pushing it as it can cause engine failure if not sorted, but you need to take the car to a speciallist, if its missing it could be a bad spark plug or lead, even a coil pack (well that black thing on your manifold), so it will all need checking.

When was the car last fully serviced with spark plugs, air filter, all fluids etc?

PS, what area do you live in?

Would also suggest trying this:- (the plugs in the diagram so you can read the fault codes)

I had the MIL show on my car so I bought an OBDII fault code reader for £20.00 which diagnosed a knock sensor fault, so I disconnected the knock sensor, sprayed it with WD40, reconnected it, erased the fault code and it's been absolutely fine ever since. I can only put it down to it being damp where we have had so much rain and I don't drive it very often!

It was serviced about 12/14000 miles ago all plugs fluids etc,
I live in Canvey island nr Basildon Essex.

These cars are 7.5k/6 monthly service intervals (whichever comes first), it needs a service (and possibly a major one, 3 year cambelt change as well if you like your engine :eek: )
A few places near you to get your car looked at, go check out the essex crew in one of the other sections so they can point you in the right direction

Thanks i am going to get it serviced as soon as poss. The mechanic put an OCD2 on the engine and it would not register and then he put a more expensive machine on itand that would not even register. Will contact the Essex Crew.
Thankyou.

Save your money and use the Scoobypedia Guide, you can then tell the mechanic what's at fault. I take it the garage is not a Subaru independent or dealer?

+1 for the plugs under the steering column, wish the newage had the same feature

Newages are far superior for diagnostics, a £9 lead and £20 laptop gives you more information then any flashing light can.

Or a £12 bluetooth adapter, and a free app on my android phone. Torque Pro

Yeah got one of the leads with software, in fact just about to order the blue tooth one and buy the Torque app for my phone as a new toy:luxhello:

You wont be dissapointed.
Here is a couple of videos using Torque Pro

i have the same model and i changed my knock sensor after a 22 fault code problem solved

and the same problem but the knock sensor is a right bas##rd to get too but is doable if u have the rite tools and a bit of mechanic skilll

Heard a loyalty about this... really worth it then? It's only a few quid anyway.
