Default Top Engine Clean

Before I change my oil next, I want to run some of that Top Engine Clean through to see if I can clean out some crud in the engine. There is just over 90,000 miles on the engine, and it'* never been done before. Is this stuff going to foul up my spark plugs, or hurt my O2 sensors in anyway?

I will need to do that when I change my TB gasket. Mmmmm. at least 5,000 miles of inhaling trace amounts of oil. When I put that Top End Cleaner in things will be ugly.
Be prepaired for lots of smoking. Its just cleaning itself out. It might foul you're plugs but the O2 should be fine.

I did it a few weeks ago before an oil change. I have 157,000 miles on it, and just very little smoke came out of the exhaust. I think you will be fine. The vacum really sucks up the cleaner fast

I used this with my OLD plugs and they still worked just as crappy as they did before.. I am sure your'* will be fine.. but if you don't have another car to go to the parts store to get more.. you might want to have a set laying around.. or if it'* due for a change throw them on, afterwards.

I have access to a repair shop, with many plugs in stock.

What product will you use for the top end clean? I have a 91 GMC Sonoma with a 4.3L engine and want to clean it out. The product recommended on the S10 forum is Seafoam.

I'm not sure what I am using yet. I will probably do it in about a month when I get my oil changed next.
