I'm going through my injectors and cleaning them. The number 8 injector is really bad. This explains why I was down on power at the end of the season last year. I'd rather replace it or all of them for peace of mind but would rather not spend over 300 bucks each if possible. Does anyone know of a direct replacement that is the right flow rate and won't mess up the PCM?

I just tried to clean it just in case I couldn't find one locally and it's completely dead. Doesn't respond at all to 9 or 12 volts. Really wanted to get this back together this weekend...

Here's a good place to call about your injectors. If he can't help you then there's not to many out there that can.

Thanks for the tip. I'll call them on Monday. I think I just need to replace the bad one as the others all tested good. I don't mind paying for OEM but I live on the west coast and don't see anyone who has them in stock. I wish it was like most of the parts where you can just go to Napa. I really don't understand fuel injectors either. The mercury part number is 805225a1 but the same injector is used on a lot of smaller motors. I don't understand how the same injector is used on a 350 as a big block without setting the flow rates differently.
