seafoam problem!!!!!!!!!!!! i seafoamed my 85 305 chev pu w/136,000 miles, it smoked some on start up. then i took it for a drive. it was fine for a mile or so. then at the next light i got on it some and it pulled good, but then when i slowed down it ran like ***. it was popping and could hardly get out of its own way. i drove it back home and tryed to clear it out,but i never did. did i foul up the plugs or what?any suggestions?
also, i checked all the wires with the timing light, they are all fireing,and it revs alright in park,but in gear it bogs out bad. HELP?

You didnt say if you put any in the gas tank, but if you did changing the fuel filter should be part of the seafoam project after the seafoam runs its way out of the system/tank. The seafoam works so well that it dislodges junk that is in the fuel lines after the filter and it may have found its way to the injectors and clogging them too to a point.
Do you have any codes? Might be O2 sensor also.

Does your truck have a catalytic converter on it? SeaFoam may have clogged it.
If so you might try and put a "test" pipe in place. But a fuel filter is what like $1.00 and 5 min work for a Quadrajet, so do a basic "tune up" first.

1/3 through carb,2/3 in tank. no O2 sensors,no cat conv. brand new fuel filter looks new still. full tune up.plugs look great. put in new timing chain this weekend because there was about 12 degrees of slop in chain. still running the same. i'm really starting to lean towards a broken valve spring, cause i was reving it pretty high before it took a ****. and when i foot brake the motor it sounds like a ford diesel on one side of engine.i'll check that tonight.

Seafoam normally dont make the motor run the way you said unless something in the emisions or O2 went bad. Bad spring wont be bad to replace

I Think I Found The Problem. The Carb Gasket Was Seperating And Cracked And Generally Disingrating. I Think The Seafoam Finally Did It In. I Put In A New One And Degreased The Carb. It Now Runs Like A Dream.
