I have replaced the Fuel Pump, Fuel Pressure Regulator, Spark Plugs, Mass Air Flow Sensor, and put in Fuel Injector Cleaner and my Blazer still bogs down when I press on the gas. Sometimes it doesn't get up to 3000 RPMs. Please with any suggestions!

 

Did you actually DO a fuel pressure test?

Did it set the Service Engine light?

 

The Service Engine Light has been on for a little over a year. The original code I got was P0101. Now I get P0102, P0171, & P0174 I believe... Low Bank 1 and Bank 2.

I have not test the fuel pressure, though.

 

P0102 is a MAF sensor code. P0171, P0174 are O2 sensor codes. I would try cleaning the MAF sensor and look for vacuum leaks.

 

you may not even have a fuel problem....

TEST THE PRESSURE with a fuel tester..autozone lends them out for free. just pay a refundable deposit.

Clean the maf with MAF cleaner...not brake or carb cleaner..
