1995 Pontiac Grand Am Q&A
1995 Pontiac Grand Am Question: COIL HOUSING
There was a bulletin on 2.3 liter Quad Engines for the Coil packs and Coil Housings. ( they would arc and fail) Are you using AC Delco parts? Are you replacing the plugs, coil boots, coils and coil housings all at once, because when I did them at the GM dealship, that is what we had to do, or the car would 'come back'? Do you have any ignition module codes like code 42 for lack of EST timing. If the module is over heating the coils because of too much 'on' time then this could be a factor. - dandd
The ignition coil housing may fail causing an engine misfire on one or more cylinders.
