after doing this i have a few tips/comments.
1. seems every local parts store was out of berrymans. i used seafoam. works fine to fill up the UIM and be sure to let it soak for a few hours. it didnt seem to eat away the carbon as fast as. . .
2. valvoline carb cleaner. this stuff is basically a power washer for your intake. literally blasts the carbon off. granted, i couldnt fill the UIM with it like seafoam, hence the seafoam usage on the UIM. on the LIM, however, the valvoline carb cleaner + a tooth brush made short work of the buildup.
as far as i could see, after letting the seafoam soak the UIM for a while, and after some brushing, most of the carbon seems to have dissolved. it was hard to get the opening where the TB sits soaked, so i used the carb cleaner there.
the how to was very helpful. if i made any additions to it i would make only one.
for the injector removal, you just have to pull. i had a hell of a time getting mine off. it just took a lot of wiggling and tugging, but they finally came out. on the return system, there are only 4 bolts instead of the 7 or so the how to states. they are all on the fuel rail and easily spotted. a small drop of oil helps the injectors slide back in much more easily.
