Hi all,
Was having trouble with my 02 Bugeye WRX but thanks to the helpful folks on here I got it sorted. I changed the cam sensor and then the MAF. Car was running fine for a few weeks but then last week when I was driving the car hard I noticed the engine light flashing.Next day same thing but this time it stayed on. I got it checked and it showed Po301,302 and 303. I had it reset. It drove fine for a week and now the engine light has come back on again.
Car seems to be driving fine though.
ANy ideas whats causing this?
Thanks for your time,
B

i had the same issue with my bug, belive it or not it was the nutrual position sensor on the gearbox. i was toled that this sensor doesnot have an error code so it just popps up missfire ussues, has it been remapped? as you can change the values if that is also in issue.

Yep possibly the neutral position switch as above. its known to bring up odd codes on some occasions including multiple missfire codes

Thanks gents.
Started the car this morning and the engine light was no longer on?

normally the nps problem triggers the misfire codes whilst on full boost in a particular gear and not all of them.. if that situation doesn't arrise again for a few ignition cycles it clears the engine light but the issue is still there and will onlyu get worse

Any idea of the cost of the senosr mate and is it hard to get to change?

Does it do it only when cold or hot as well ? Had the switch changed on my 2002sti and it still does it , only when cold though , have read on here it can also be triggered when too rich which could occur when cold . Car has fully decat , fuel pump , air filter and re-map .
