efseiler Posted July 27, 2011 Share Posted July 27, 2011 Hi, What's the fuse to disable ignition. I'm going to suck Seafoam into the throttle body and I can't remember the fuse to disable spark.... I've a 98 OB with a standard trannie.... --Damien Quote Link to comment Share on other sites More sharing options...
eulogious Posted July 27, 2011 Share Posted July 27, 2011 Why do you need to pull the fuse for the ignition? I thought the car had to run inorder for seafoam to work. At least mine was running when I did it... Unless I am missing something here? Quote Link to comment Share on other sites More sharing options...
efseiler Posted July 27, 2011 Author Share Posted July 27, 2011 well yes but in order to effectively apply the solvent the engine needs to crank but not start...this draws the fluid in and applies it to the valves, pistons, rings etc. without combustion... Then I wait ten minutes, put the fuse back in and start the engine.... --Damien Quote Link to comment Share on other sites More sharing options...
eulogious Posted July 27, 2011 Share Posted July 27, 2011 I gotcha. I usually just pour it on in while it's running. Never really thought about letting it sit, good idea, will have to try that next time... Sorry, I don't really know where the fuse is for the ignition, so I can't help you on that front. I have a 1990 legacy, so I am sure things are a little bit different between our cars. Good luck! Quote Link to comment Share on other sites More sharing options...

CNY_Dave Posted July 28, 2011 Share Posted July 28, 2011 I think that you are MUCH SAFER pulling the fuel pump fuse. Pull the fuse, start it and run it until it stalls. If it will run on the seafoam, pull both. Dave Quote Link to comment Share on other sites More sharing options...

efseiler Posted July 29, 2011 Author Share Posted July 29, 2011 I guess that would be fuse #16...says 'Engine Ignition System' in the owner's manual. Sound correct? --Damien Quote Link to comment Share on other sites More sharing options...
WoodsWagon Posted July 29, 2011 Share Posted July 29, 2011 I always let it suck the seafoam in while it's running. You keep the idle up and let it suck it in as fast as it can without bogging, then let the throttle go while it's still sucking it in and it stalls. Let it sit for 15 mins, and fire it back up. Either use the PCV hose coming right off the valve or one of the ported vacuum hoses on the throttle body. There's not much airflow when it's cranking over with just the starter. I'd be concerned about the seafoam puddling in the intake manifold rather than getting onto the valves and cylinders like it should. Quote Link to comment Share on other sites More sharing options...

efseiler Posted July 30, 2011 Author Share Posted July 30, 2011 I used a pretty copious amount in the tank and after about 1000 miles of driving the backfire/sputter is almost gone. One thing that also happened was one of the thin EGR hoses popped off the solenoid? I think it was. There was a lot of black carbon dust that spewed over the engine. I cleaned the EGR valve assy with a pipe cleaner and now the engine is running better than ever. Seafoam is a product that really seems to work....:-) I would also re-recommend Shell gas as the difference is horsepower and pickup is really very noticable. Other brands use more ethanol/methanol and sometimes even mix in a little water. I've been using 'Startron' which bills itself as an 'enzyme' cleaner. When using cheap gas I noticed a slight increase in pickup/hp. Another thing I noticed was in the exhaust...it was 'puffier' (if you will) and no dripping water out of the tailpipe.
