Alright 7mm supermag silicone wires,My Bosch platinum spark plugs seem to be working fine. I also ran my car in FWD today it seemed to run a lot better even though I had the incorrect tire sizes in the rear! I put some Goodyear tires the correct size in the rear 185/70/14 this evening & she's running 10 times better!!! No stutter,or jump! A front tire balance & front end alignment will be needed asap, I'm sure this is causing the remaing vibration in the front... This is also making me wonder if I should still replace the O2 sensor? She ran fine till I had some idiot put the wrong size tires on the rear?!?!

Bosch platinum plus.... I had NGK'S before

She only starts stuttering/jumping/shaking at 50 mph+? I've tried down shifting with the car in D, but I havent tried down shifting into 3'd.... it feels like a old spark plug or wire, but I've replaced both along with another coil pack! She responded the same!

Ok so could this have something to do with the shake as well? I will have them replaced tomarrow hopefully along with a alignment.....

WOW I didn't know that! I thought it just ment the tire was Wider? Ive been told you need all the same size tires before! I would've never thought being .5 wider would make a huge difference....

Ok so I don't have a check engine light?300K Used motor @ 150K So I was told from the previous owner... she only seems to act weird at high rpm/speeds. I've checked everything listed 3-4 times just to make sure. I'm renting a crows foot tomarrow to replace the front O2 Sensor with a used one from another Subi with half the miles on it! It's really weird my cars never done this before, just recently she started acting up! I haven't had an alignment in a good while? I have good tires 185/70/14 Front -185/75/14 In the rear I had put on a week ago...

95 legacy wagon 2.2 At..... Hello Subi world I'm in need of help! I have a 95 legacy wagon that's having a jumping problem at 50+mph! It feels like a bad wire/spark plug... I've put new plugs,tried different wires,coil pack,check all fuses,fuel filter,getting a constant flow of gas from the fuel pump,MAF seems to be working,knock sensor is new,air filter,new ball joints,hubs,& sway bar links. Front struts good, new rear struts,good tires..... I've pulled a few other sensors, one under the alternator,& another on near the driver belt the same color orange. They seemed to be ok, the one under the alternator had a small dent on the bottom? Idk what's going on but if feels like a huge miss at 50mph+ ??? Jumping stuttering sputtering & continues after that even at lower speeds??? Seems to do this once the engine is warm? Any suggestions would be great, I'm stumped & my mechanic charges 75$ hrs for subarus.....
