My subaru is having issues. You cant just jump in and take off in the morning, it needs to (warm up). If you try to take off it bucks and kicks and is extremely under powered. It idles really low on cold startups also. But then sometimes, this problem is gone. The idle is high and it doesnt do this on cold starts. There is no difference in situations. Also after its warmed up at a stop light it will rev buy itself 2 or 3 times then idle fine. What could possibly cause this.

the timing is bonkers, mine was like that for a while. It could also be connected to the carburetor or a vacuum line in some way.

What about a sticky, "Air control valve".?.. it sits on front of throtle body and regulates air flow at idle etc... 3/4" black rubber hose comes off it and goes back too the Mass Airflow/filter box, ... remove hose and shoot some silicone spray into air control valve... note if you remove hose from that while car is running it will die or idle funny...

and what about a dirty Mass Air flow wire down stream of the air filter... possibly spray down with brake cleaner...

Kind of shooting in the dark here but there are two ideas that caused rough/random idle on my 88 wagon.

Yours is Carburated? ... if So, Blame the Choke And/or the Vacuum Lines.

Good Luck!

My car chewed some of the cogs off the belts, so it would run fine at higher rpms, but sputter at idle and lower rpms.
