Hi, The car is 9000, 2.0 LPT, year 1997, 100K miles on the clock. It showed some random misfire a week or so ago. Two days later took it to the SAAB dealer who could not fix (not enough time), but replaced some split rubber pipes relating to the turbo (?). They think the misfire relates to the turbo, as it does not supply high enough boost. At the time the misfire was only when the engine was under load and gentle acceleration (town driving). ============ The car is booked to go back on Tuesday (by which time it may well need a new catalyst... that will become an email of its own if it does). The misfire now happens after about a mile from cold (or a bit sooner) and it happens even when the engine is idling. I can't see what this may have to do with the turbo. Any ideas, what it may be or which is the best way to identify the problem? BTW. Are the recommended sparking plugs for the car NGK or Champion? TIA Charles PS. My experience unfortunately is from early non-turbo 900s with conventional ignitions. -- Please remove _removeme_ to reply.
