so..... nothing new here.. my hoe wont idle.

Happened yesterday while driving. I came to a redlight and it almost died. so I held the brake and gas and it idled back up.. drives fine when at speed, but if i let off the gas all the way at anytime, it dies. even if im cruising at 55 and let off the throttle . wont hold an idle. even in park. Ive tried every different scenario. As long as i have my foot on the throttle it will idle at whatever rpm i choose, but if i let off it sputters down to 200 then dies.

list of things done.

TB cleaned
Maf cleaned
EGR valve cleaned

Items replaced

Fuel filter
MFI conversion
IAC
plugs
wires
rotor
cap
PCV
coolant temp sensor


Any thoughts?

Check your fuel pressure.
Sure sounds like a failing pump to me.
Does it start fine?
If not try turning the key on, let the radio come on/or until you hear pump shut off.
Do this 3 or 4 times. Last time go from key on to start.
Did it start easier? If so more then likely a weak pump.

I agree. Prime the pump a few times and see if they makes a difference. Notice any stuttering/delay during accelerations?

I see, does it start fine when cold? I gather SES light is not illuminated right?

 

[2drhoeon4s]

yeah it always starts fine if I have my foot on the gas a little. no ses light...

Problem resolved i think. Swapping LS motor in it.
