Well you used the right products and set up........


Check your fuel pump pressure.

 

thanks and thats what i thought. do you check fuel presure at the bleeder valve on the fuel rail?? what psi should i be at?? havent found any vacuum leaks. narrowed it down and just around 3100 to 3300 rpm is when i start missing. does anyone know or can show me a link for testing the sensors? volts,ohms? map, iac, tps, o2? i replaced the tps after i bought the truck so doubt thats it but could have gone agian. and whats the right ohms for the injectors? thanks agian

 

You check the fuel pressure on the valve that you are talking about. Drivers side fuel rail in the middle. Pressure should be at least 50psi....... 54psi is new.

Other people should weigh in.
