Take it to Auto Zone and have the codes downloaded and read.

AnswerIf you download the codes (as above states) and they are too cryptic to decipher, then:

Could be any or all of the following:

Fuel pump - not working at full capacity

Fuel lines - restricted somewhere

Injectors - clogged ( or still clogged in your case)

Connect a fuel pressure gauge to the fuel line just before the throttle body and see if you are getting enough pressure (15psi). If not, then your fuel lines should be inspected and if they are OK (which is probably the case) then the fuel pump should be replaced. If the pressure is good then you most likely have a problem with the injectors. These can be replaced at a cost of a few hundred dollars or so.

also if you have the avability of the a tech 2 after checking the fuel system first to check the injectors you want to prefrom what is called an injector balance test, which will test each injector for it proper function. But normally if you have a misfire use the tech 2 and look at engine misfire this will tell you which cylinders are misfiring check the plug wires with a approved spark tester and then you might want to pull the plug and visually inspect it also

check your fuel pressure regulator 1st then injectors, independent ingnition koils, then your fuel pump( the fuel stst. cleaner could have knocked a piece of carbon lose in your injectors and is npw cloging it. O yeah check your pcm

I had my engine swapped and got the same code reading. So we put in some high octane race fuel to clean out the engine. And yes it did work!
