I am at my wits end with this &$#^$%@ Buick. I had a problem with my crank sensor that put me back a month of figuring out what was wrong. Finally a buddy of mine found a loose connection on the crank sensor connector and we fixed that. Car ran great for about an hour than started to sputter, backfire, and barely ran so I nursed it home. Let it sit for an hour but only ran for about half hour than it did it again, sat another hour than after 10 mins it did again, sat another hour and than would barely run. So I pulled the plugs and saw that the plugs were COVERED in fuel, like soaking wet. So I changed the plugs and it ran decent for a couple minutes than died again. I next unplugged the MAF and the car ran fine (got an SES light and it wouldn't run really well, obviously it dosent know the amount of air being added to the motor). So I replaced the MAF and it ran fine for about an hour than the @%#$@^!& sputtering again!!! This time it would start and run after about 30sec-1min of cooling off and run ok for a bit and than die again. So I called G-bodyparts and talked to them and they said it was my ICM. Replaced that today and it ran great for an hour than the same $%#%@^ thing again!! I am so fed up. So I grabbed my spark light and hooked it up. The car at idle has great consistent spark but as you bring idle up and the sputtering begins it starts to cut out and eventually there is almost no light up just before it dies. So I think it is the ICM still ?? Maybe with my luck I just got a bad one the first time around??? What do you guys think?? My fuel pressure remains constant this whole time so I would assume its just a spark issue if the spark light dosent work when it sputters right???
