Hello everyone, I'll do these one at a time. The O2 sensor was probably never changed. I may be able to check it. Prob. does get worse as car warms up. (most times) I've been told Idle control just needs to be adjusted for idle speed. Oddly small adjustments make no changes. The map filter was changed first. It was filthy, Subaru mech at the parts store said he'd never changed one. Sprayed propane at maifold gaskets and vacuum hoses and changed hoses that didn't fit tight in the winter. I should have time over the Holiday to do some more troubleshooting. But I have two shocks in the trunk that need to get put on first. Thanks for the help. Have a great weekend!

I have a hesitation problem that gets worse with fast acceleration. And can completely go away at times with normal driving. Car will cruise at 60 to 75 for hours and then act up as you slow to 40 to 50. Gas pedal acts like an on off switch. Not really noticeable under 40. Also idles high in gear and sometimes shifts erratically when cold. If you take it out of gear the idle drops to normal. (Auto transmision) Changed TPS, Maf, cleaned EGR (it works) cleaned IOC.(Closed at idle) Checked and replaced vacuum hoses. Replaced fuel pump and filter. Checked fuel vent line from tank to engine. No vacuum at idle from canister to EGR. New plugs and wires. Never found vacuum at idle at purge control solonoid, press. reg. or press. sensor. Auto zone checked, - no codes - no light. Wiring to eng. computer looks fine. Going to change timing belt when I get the chance. Car has 188,000 miles on it. I know the previous owner, he got rid of it for this problem. I'm at the point where its costing to much to fix. I still believe its a manifold press. problem. But I am now lost. Any suggestions would be appreciated.
