9-3 2.8 Aero hesitation
Discussion
I have recently bought a late 56 plate (updated dash) 9-3 V6 Aero and I'm really enjoying it but it did have a hesitation/stutter when in a high gear/low revs and then putting your foot down. I have read that the coils are a weak point on this engine and chanced that it would be that.
One thing to note is that the engine warning light doesn't go out after 4 seconds when the ignition is switched to the ON position, however it does go out when the engine is running and has not come on while the engine is running. The problem seems more pronounced when it's been running for a while, more or less fine when cold.
I have taken it to a Saab specialist in Bristol and they have said that when they plugged it in it didn't show any faults for the engine. They diagnosed the problem to be the spark plugs and changed all 6, having had it back it's much better with no stutter but I can still feel that it's not completely smooth in the above described conditions. Also the engine light is still staying eliminated when the key is in the ON position.
Car is on 72,000 miles.
Any ideas guys?
