picked up some stuff for the '93 today


I do have one question though. with the seafoam, do I do it BEFORE I change the oil, or AFTER? also, what vacuum line do I suck it up with... I did some searching and came up with evap caniser line and trans modulator line. does it matter what one?
also I have seen people say leave it set for 20 minutes and people say set for 3 hours.... how long?
last thing.... is it MANDITORY that I change out my plugs? they are only like 2 months old, and I didn't pick up any new ones. will I be ok leaving those in there?

I do it before an oil change, use the brake booster line, let it sit 20 minutes. Plugs are so -so. Sometimes they get fouled, often they don't
I've never done a */c 3800 thou. so not 100% on which line to use in this situation.

Hmm, I don't know about you, but I haven't heard to many good things about Bosch oil filters (Purolator = Bosch)... I usually go with Mobil 1 (worth the extra IMO)

Yes, four quarts in that jug.
I am not all too worried about the oil filter. I have never had a problem with ANY filter before, plus I just removed a "stock size" Bosch filter, and installed the 4.3 liter size filter.
I used up the seafoam and changed the oil.... boy the car is one super happy camper now
Idles MUCH smoother and has WAY WAY better throttle response. now I just need to actually take the TB off and clean it up

Hahaha, Hey Ryan...
I've got my TB off now, waiting for it to dry...I'm out in the garage cruisin' BC...
watch out for those IAC screws, I broke both off, had to tap & die new ones in...
I bought some seafoam too...I'm gonna do that tonight, I plan on staying up pretty late, I want to do it when the neighbors won't notice
At this rate, we're gonna have the fastest cars at the meet! (as for me, probably not!!)
