Re: fuel injectors (-10sp)

Thanks for info Dave, I really don't have the option of going to a fuel
injection specialist here on Guam, believe it or not it would be cheaper
for me to replace all the injectors vice bringing it to a shop. I'm going
to
go ahead and replace the cold start valve first and see what happens, I was
quoted $68 for one. Is it possible that this valve can be stuck open thus
flooding th engine with more fuel than needed? if the valve is not the 
problem, then I'll go ahead and replace the injectors and seals. I was also
quoted $57 ea for the injector, $1 ea for seal.
