2.5 wants to die

[thisismylife]

I have a 1998 outback with a 5 speed and a 2.5 motor when you are driving it is ok but when you come to a stop it wants to die it will start to shake any one have any suggestions on it thanks for reading

Sounds like fuel starvation - this could be a sign of the idle being set too low.

Not throwing a Check Engine light? When was the last time the fuel filter was changed? Has the fuel pump ever been replaced?

I have no idea when the fuel filter was change I will buy one and give it a shot thanks ill let you no and ill try to play with the idle

If it runs ok while driving the fuel system is delivering quite a bit of fuel unimpeded. Low pressure, plugged filters, intermittent pump failures will all be noticed more at driving speeds where fuel consumption is maximized, in fact a thorough fuel system check always includes a “pressure drive test” where the fuel pressure is monitored at driving speeds, and full acceleration.

Two major culprits for dieing off at idle is 1.) Idle set point, (too low) as Freakray had said. 2.) Secondary ignition, plugs (& plug gap), plug wires.

Does it also start hard? Too wide of plug gap will cause this. Should start almost instantly 2-3 revolutions.

Last week had a plug wire that was causing the very same symptoms and throwing a CEL code. #2 misfire, duh! the plug boot on the end of the wire was empty! It had been damaged inside but looked perfectly normal on the out side, tell tale was no "click" when pushed on the plug.

Ill look in to it thanks you I put a new fuel flitter on and play with the idle nothing I ran it for codes and it says #1 miss fire and #3 miss fire so Im going to go buy new plugs wires and swap them out thanks agene

You will not be disappointed with the results from replacing your plugs & wires.
Just be careful not to break the porcelain exterior of the plug when installing them. When tightening them keep the deep socket parallel with the plug at all times when installing.
It really helps to remove the air cleaner and snorkel including the base of the air cleaner. Also remove the windshield washer tank.
Tools needed: 5/8” deep socket, 3/8”drive universal,(installed at the socket), a couple of 3/8” extensions.
And LOT and LOTS of patience.
Afterward readjust your idle since it was not running to well when you tried to adjust it before.
Good luck
Please post back with what you find out, that way we all learn.

Check your codes!
They must be cleared!
Most of the parts stores have a reader that they can clear it for you.
