Hi all, my 95 GC8 import WRX has developed an intermittant misfire when at full working temp and underload, it has been re-mapped and runs at 1.2bar and has run great for a while and does when cold! Im suspecting poss ignition coils or the plug caps! has anybody heard of anything simular?

cheers

yup id be checking the coil pack tips for cracks. The problem is more pronounced when when run that much boost.

 

Thanks for that, do you know if there are uprated or modified coils packs availible?

 

non that i am aware of

 

I believe Bosch ones are better, but dunno where from ..

 

Change the spark plugs first...spark plug failure is far more likely than coil packs (unless a heavy handed monkey previously removed the coil packs and cracked/stressed them ).

 

Had same prob running 19psi ....changed plugs and re-gapped to 0.6mm and has cured problem.
Had few people say could be coil packs...but it wasnt so try plugs first.
