....my wrx import 1995 is running very lumpy and mis-firing itermitandly in low revs.....someone mentioned the coil packs...does it sound like i need some news ones?

 

quite possibly.. if they haven't been replaced already then they are long overdue a change.. whcih is difficult to be sure if you haven't owned it long mind.

Make sure the spark plugs are OK, I had an issue with a sort of miss with the engine. Tried everything but turned out the garage had either fitted the wrong kind or gapped them wrong at the last service.

 

ok mate - they are new in last week when it was serviced but it really is running like a bag of **** now - only at low revs though...high revs and on boost is still sweet as....so confused?!?!?!?

 

Could be a MAF (Mass Air Flow) problem. Faulty coil packs tend to cause problems on boost rather than at lower revs.

 

oh really?
so theres no point in getting coil packs just yet then mate?

the thing is i have a K & N INDUCTION KIT fitted....does that mean it could still be the MAF?

 

James, read the thread 'Stuttering/bogging down' further down the page.

 

thank u - so could it really be as simple as the fuel being used?

i use sainsburys super unleaded 97ron stuff.......

 

James, that thread was more to do with changing from Optimax to V-Power than the petrol you're using, so could be a different issue. Help anyone ?

 

gonna try take it to a garage this wk

 

I could be wrong, but I'm sure that I heard somewhere that the oil used in the K & N type filters wrecks the MAF.

Anyone know anything about this ?

 

ive been told that if it was coil packs i needed then the probs would occur at high revs and on boost (is that right yeah?), however mine only does it intermitantly and at around 3,000rpm. maybe gona start with a new MAF.....

 

Depends what boost you are running.. but yes that is correct..

Simon

 

thanx mate - i think its running @ around 1.2 bargoing by the gauge...

 

Then I agree it is unlikely to be a coil pack problem..

Simon

 

cheers mate - dropped it of at the garage now for a few days while im away with work - hope to **** they find out whats wrong with it!

managed to get a 2nd hand MAF, so hopefully that can go on this wkend.....
