Injector/Manifold Fouling Question

[flint54]

Ok, so I finally gave into the urge to buy a set of injectors from the Precision Injector folks

(http://www.precisionautoinjectors.com/), who happen to be just a few miles from me. You've

probably read or heard about them here or elsewhere. Got the tour - cool setup - nice guy!

Saw more injectors then I thought ever existed. Anyways, I've pulled out my old ones, the

originals and never before removed with only 75k miles, and I saw lots of black crust in the

manifold bores - Lots of it!! Never encountered the likes of this before, even on much higher

mileage vehicles. So I'm wondering if you all think I should just ignore it, or try some brand

of marvelous snake oil that claims to remove this crud, or pull the manifold and boil it (don't

really want to do that), or just yank this motor and go for the stroker Opinions please.

BTW, never had any problem with how it runs or fuel consumption (20-24 highway) but

wanted the flow balanced, four hole, Bosch units to see if they make any difference.

Gag it on Seafoam a couple times.

20-24 MPG, makes me wish.

 

My opinion, don't fix it if it aint broke. Unless you just need to spend money on it.

Well, I should 'fess up. The 20-24 mpg is real, and carefully calculated

on long interstate distances, but that was when I had the 3.07 gears, and

I'm certain the 3.55's will lower that some. On the money side, my

darling bride of 31 years will tell you (but pay no mind to her sarcasm)

that I have a long standing habit (she calls it an obsession) with improving

vehicles, one at a time. The list is long, and right now it's a Comanche.

I tell her that, if it weren't for cars and trucks, I would be spending the money

on things she would certainly not approve. :D

 

I may try the Seafoam, because I hear it makes great billowing clouds

of smoke, and will give my neighbors something else to talk about.
