So I have a 95 legacy wagon 2.2 4eat with almost 200k miles. Ok so in the morning when its cold the car idles a bit rough and has no power if I try to drive it right away. If I give it a minute, maybe less, it drives like it should. Then, sporadically, the car will feel like its trying to stall if I give it too much gas. Like it will ref up to maybe 1500 rpms and then drop off to almost 0 then rev up again in a cycle like that. If I let my foot off the gas just a bit the rpms will rise and the car will drive like it should.....car is also throwing a knock sensor and egr evap code (p0325 and p0441 I believe) ive swapped out the map and maf sensors and think it may be the iacv or coil. Ive also looked for vac leaks and found one at the map but fixing that didn't help.....Looking for some ideas. Ill pull plugs Friday too see how they look but they were replaced relatively recently.
Thanks in advance.
Ill try and get a video of the cars odd rev cycling too....
