Question about 1997 Pontiac Bonneville
My 97 bonneville's lock up converter make the vehicle chug..it seems to be trying to lockup but disengages causing a chugging action of the vehicle....i took this vehicle to a gm dealer in east tn as i was told this vehicel came here from up north and it has to have a chuggle program installed....they supposedly installed it but the vehicle still chuggs...is there anything that can be done to solve this issue???
A GM dealer should be able to reflash the PCM to help alleviate the chugging.To a certain extent,it is normal,and you might want to consider tuneup things like plugs and wires,air and fuel filter,and also have all the engine and transmssion mounts checked for weakness,as weak mounts will magnify these types of problems.
