Thanks for the help, will clean the injectors with carb cleaner. Then if that does not help will swap the stock air intake for the CAI

Whats the new injector type. Didnt they upgrade the spider assembly? My 2k blazer is loosing fuel pressure when it sits and takes longer to start. Been looking into replacing the spider assembly.

pre 03 it is a SCPI sequential central point injection
post is MFI multi-port fuel injection
Got this from rockauto: DELPHI part #FJ1056511B1, $230 with the new bracket included, and don't forget to Google a discount code, should cover most of the shipping
