1998 Pontiac Bonneville SE 3.8L Poor Idle Quality, Hesitation, Surge, Cuts out, Stall, Misfire
Posted to GM Driveability on 3/12/2011 40 Replies

Thanks in advance to all that reply, this is a car that ive had in here for the past week and its very frustrating. It runs great on startup and you can drive it with all the power it has. But after 20 min or so, there is a bad miss and it backfires constantly...
