I'm a new guy here, can't find any rules or tips how and when to post, I'm getting really frustrated, Please, I need some help! Here's the problem, I've got Subaru Legacy L 2001 Automatic, bought it three month ago, the car was having issues with a radiator cap, I replaced it and started to drive. In a couple days CEL popped out, misfire cyl 2, misfire cyl 4, some vacuum leak, and Map sensor. Here's what I did:Put new NGK spark plugs with a proper GAP, new NGK wires, new coil pack. Changed the oil, and filter. After that we erased the codes, after 10 or so CEL code - misfire and MAP sensor. Next thing what we did, checked for the Fuel pressure, which was good, and cylinders pressure two of them were around 120 and two of them around 95-100, which I think is Okay.. Next thing, got the MAP sensor from ebay used one,installed and cleared the codes after, drove around didn't feel any difference, CEL is on again - MAP sensor. GOT new knock sensor with a TPS sensor, installed it today and cleared the codes, and no difference. Ordered the MAP sensor from ebay again, but they send the wrong one, doesn't fit on mine, it's more for 2004 legacy or others, so had to send it back. Mine part is Bosch 0261230013, and of course autozone or advancedAutoParts don't have it. Ebay has it but for Hyundai which is okay I think? So I'm planning to get that one. Here's what the car is doing: start's up and RPM are going to 2500 right away, then slowly goes back to 900-1000 , and shakes; sometimes badly and sometimes not really noticeable. After 7 min of warming up I'm trying to drive but there's no way I can, the car is in the stage of a "hitting a wall" or "loss of power" and hesitating. And only happens under load, doesn't happen in neutral. I had to stop and put emergency lights on, because the car wasn't moving faster than 2 miles per hour and it doesn't matter how much you pushing on the pedal. However sometimes It's getting better(pushing on the pedal and sounds like the air stuck somewhere, with a sound of misfire-very rarely but it happens) Here's the tricky part, after 2500-3000 rpm it takes a second breath and drives like crazy, no issues, no hesitation, a lot of power, until it goes back to low rpm, and becoming badly again, sometimes even dying. On the parking works great, responds great. Tranny shifts good, around 2500-3000 rpm Also, when I pulled the MAP sensor it was all oily, and inside of manifold looks kinda oilish? Don't know if that's okay? I would appreciate any suggestions. Thanks
