91' ROUGH Idle/Stall out. HELP
alright boys, here we go.
I havne't noticed this creeping up or anything - just happened today while on the highway for a while - came into town and hit a stop sign... then she was idling at about 400 rpms - almost stalled out - a few times while in park it actually did stall out.
heres what i have noticed
-pretty good humming coming from the gas tank ( fuel pump )
- when i press the brake pedel a few times - it idles almost normal ( vacume leak)
- gave it new plugs/wires/cap/rotor - sea foam throttle body and even got a new TPS
- used carb cleaner around vacuums lines - couldn't find any problems.
- there was a screw plugging one vacuum line, ( been there forever) took it out and it will idle about about 400 but not shaking and stalling..
there is all i got for you gurus out there - help me out and lets see if we can't narrow this down.
Happy Memorial Day.!
