My guess is that it has. When bad, it reduces ign advance causing significant fuel consumption, pwr loss. It can be bypassed with5c resistor, read page9 how/why/what, & possibly youll find 'where' via top left 'Favorite Links' first clic link below.

Try some injector cleaner.... the ones you dump in your tank work pretty nicely...... at lot of the older car's are getting clogged injectors since they switched up the gas.

Normally if it doesn't help on your first tank, it's not going to help at all.....never used seafome.... we use a product call power charge from wynns..... it works great.
