need help

[donzz]

my '93 explorer with about 10kmiles since rebuild is running like **** seems to be fuel delivery problem .Replaced the relay fuel filter is less than a year old. feels like it is running out of gas if I punch it once it kicks down into passing gear it smothes out I dont think its a transmission problem because it does the same thing idling in park any ideas?

have you checked the plugs and wires?

what is your fuel pressure at the rail?

filter is less than a year old

what is less than a year? 6months, 9 months, 11 months If your tank is dirty you may need to replace it every 4 to 6 months

Is the check engine light on?

check engine light is not on
filter is 11 12 months old
plugs and wires 5 months old
thanks for the help

the cheapest thing you can try is to go ahead and replace the fuel filter. you really need to check the fuel pressure

did you set the TPS voltage to .95v ? becuase that will make a huge difference in throttle response
