Engine management light on WRX
Hi guys and girls ;0). I have have a Subaru WRX 2002 brought secord hand direct from subaru and I keep getting the engine magagement light on when every I drive over 80 mph. I kept taking it back and they kept resetting engine magaement and saying bring it back when It comes back on which I did and I kept keeping the same answer bring it back again. I finally got them to replace the engine coils but again Getting the magagement light on so I took it to another garage they did me a engine magagement print out and I'm getting a misfire on cylinders 1 2 3 4 so they have recommended I replace all 4 coils again. But after speaking to a friend they have advised me to replace the spark plugs and leads.
SO THE QUESTION IS. Whats the spark plugs and leads I can buy for my year at a reasonable price and has any 1 else had this problem and if so how did they solve it. (my car is always mantained and not just raced about with no maintance)
Many thanks. (and PLEASE HELP)

i'm hoping someone technical may help you - I have a simialr problem.
My engine management light comes on during hard pulling in 3rd or 4th gear, it flashes and then stays on. It stays on for about 2.5 days and turns off again. I wait another week and it comes on again. The dealer I brought it from said the car showed it was lead 1.

Sorry to hear your ownership isn't going so smooth.
If you purchased the car from a approved Subaru dealer you would have had the warranty (12 months) . If it is within this time take it back or take it to another one matey.
Where abouts is your location.

Hi thanks for the reply. I had the same Prob with it only flashing then saying on for a few days then going off but now it just stays on. I've spoke to a few ppl and they say the same thing change the plugs and leads because I only had the coils changed 5000 miles ago.
I live in Romford, Essex, UK. So if any 1 knows of a good garage around my area then please let me know.
Mant thanks.

Sounds as if changing the plugs may be a good idea though.

Mines completely standard - although if I change the exhaust with it cause the light to have a minor tamtrum? Anyone got any good suggestions to the best plugs to use - is it worth changing the coil packs too - i used to have a megane that threw out a coil every couple of months - drove me mad!

Bugeye ECU random CEL Generator LOL. Camshaft position sensor error common at high revs, sometimes goes after a clean of the sensor. You should have the historic code stored on the ECU even if the CEL light goes out.
The other one is a faulty neutral position switch throwing spurious misfire CELS.

I'm going to buy 4 NKG or Nology spark plugs today. Get them fitted and the engine light reset if I still get same problem then change the coils and hope for the best.

See my post number 9....... do a search on here for faulty NPS problems giving multiple misfire CELS on the bugeye..... for example.

I have just re-read the OP post and need to ask a question.
Martin.dean1981 , does the car feel any different once the the light come on?
Any smells etc?
I think its a 2001 WRX thing. I remember my old WRX throwing up a code in the same place of the M25 if I was between the speeds of 70-80 mph.
Any modifications to the car at all?
Do you have a DV?

More than likely the WRX pre-cat has been replaced..........and the new up-pipe either has no EGT sensor hole or it's been blanked off. I bet there is a spare connector by the offside suspension turret (where the EGT lead should be). LOL
