so just did the seafoam and now for some reason my acceleration is crap (only got to 60 on roads that i could reach 80 easily). so could it be the spark plugs? or would it be something else?

used half a bottle thru the vacuum line, and the engine didn't seize up. It sat for about 10 mins and then let the smoke clear out and drove it.

thanks in advance!

 

Could be plugs, what do they look like? Or some of that carbon you loosened got caught up in something (chewed a bearing, etc.) Or the loss of the carbon buildup exposed leaky seals, etc. Can you get any trouble codes out of it? http://check-engine-light-codes.blog...retrieval.html

 

nah no code or anything, plugs looked good too

 

Try a compression test. Then a leakdown if there's loss of compression.

uuuummmmmmmmm.............

did u put back the hose?

 

The vacuum hose? That wouldn't effect his acceleration. Obviously you need to do an inspection of all the parts in the "power" line of the engine. Spark plugs first.

 

Could have burned ( melted your catalytic converter)

 

It may have finally taken out your oxygen sensor that was already on its way out.

 

well before doing the seafoam i put my stock air box back in but i didnt have the screws to keep it locked down, So i though that was the problem and put my sri back in. Seems to be running back to normal. thanks for the info guys.
