Buzzman Posted April 30, 2012 Share Posted April 30, 2012 Just as the title states. I understand theres little correlation between the two but does anyone have a clue as to why this would happen. The car literally shakes in first gear up to 2000 rpm. I don't know if they hit something, or its coincidental but I'm obviously concerned.

whitetiger Posted May 1, 2012 Share Posted May 1, 2012 im gonna guess that it was the passenger side front axle that was replaced. if so, both 02 sensor wires are in that general vicinity, sorta. no CEL? you say up to 2000rpm. is that when you rev it, or when you drive it?

Buzzman Posted May 1, 2012 Author Share Posted May 1, 2012 Yes passenger side and when I drive it. It also shakes at idle, too. I google'd it and found out that the mechanic might not have replaced the axle with a genuine Subaru one and that could be the problem which I hope is. Not throwing any CEL's though.

whitetiger Posted May 1, 2012 Share Posted May 1, 2012 if the car is shaking when not moving, then its not driveline related. id look for damaged wiring in the area of the axle. thats why i mentioned the o2 senor wires Link to comment Share on other sites More sharing options...
Buzzman Posted May 1, 2012 Author Share Posted May 1, 2012 Would that throw any kind of cel? Only asking because you mentioned it in your first post. Link to comment Share on other sites More sharing options...
whitetiger Posted May 1, 2012 Share Posted May 1, 2012 it may, it may not. it depends how a wire is damaged. the only way to daig a running issue, other than visually finding the issue is to monitor your sensor outputs with a diag tool and look for things out of norm. now im just speculating here based on your description. if you think the issue is a direct cause of the axle install, take it back and have them shop find it.

Spun Muffler Bearings Posted May 1, 2012 Share Posted May 1, 2012 It's pretty common to get a weird shake at idle with non-subaru axles. Take it back for a polite wtf? session and may the force be with you. Link to comment Share on other sites More sharing options...
whitetiger Posted May 1, 2012 Share Posted May 1, 2012 ^why would an axle that isnt moving at idle cause the car to shake. while moving i understand, but not at idle when the car is stopped. Link to comment Share on other sites More sharing options...
Buzzman Posted May 1, 2012 Author Share Posted May 1, 2012 Oh I did. I generally go to the Subaru dealership for all maintenance but my dad recommended this mechanic to me so I tried him. The kid told me that it was my fuel injectors and had the audacity to tell me that it came in the shop that way. I said it's definitely not the fuel injectors, too coincidental. Honestly, I really don't like the shop so I may take it to the dealership and see if they can find the problem first. The 'mechanic' also suggested I come in for a tuneup, I said no Link to comment Share on other sites More sharing options...
Buzzman Posted May 1, 2012 Author Share Posted May 1, 2012 Would an access port be able to diagnose a damaged 02 wire? Link to comment Share on other sites More sharing options...

whitetiger Posted May 1, 2012 Share Posted May 1, 2012 Would an access port be able to diagnose a damaged 02 wire? only if the car has thrown a code. take it to a dealer. Link to comment Share on other sites More sharing options...
Buzzman Posted May 1, 2012 Author Share Posted May 1, 2012 Yeah I have finals this week so I'll probably set something up with them this weekend and report back. Link to comment Share on other sites More sharing options...

StoplightAssassin Posted May 1, 2012 Share Posted May 1, 2012 Would an access port be able to diagnose a damaged 02 wire? possibly. check AF Learning 1. it would be all over the place (+ and -) while cruising if the front o2 sensor itself was the issue. I can't say if it will show the same way if the wire is damaged. Link to comment Share on other sites More sharing options...
brad_houck Posted May 1, 2012 Share Posted May 1, 2012 im wondering if he disconnected the battery for some reason. if the battery is disconnected on a higher mileage car it will cause a rough idle til it relearns the idle airflow if there is build-up at the throttle plate.

Buzzman Posted May 1, 2012 Author Share Posted May 1, 2012 Well the AF Learning 1 stayed in the positives, went up to 2.3 I'll be taking it to the dealer soon so we'll see what happens Link to comment Share on other sites More sharing options...

I meant to say AF Correction 1. My bad. AF Correction 1 will be all over the place while cruising if the o2 is bad. Link to comment Share on other sites More sharing options...
Buzzman Posted May 1, 2012 Author Share Posted May 1, 2012 Ok, thanks stoplight, I'll check it out when I'm cruising to the dealer today. By any chance, do you drive on 130 near Delran? I could have sworn I had seen your car in the summer. Link to comment Share on other sites More sharing options...
StoplightAssassin Posted May 1, 2012 Share Posted May 1, 2012 Yeah it was probably me. Sometimes I'll take my car out on estimates since I don't drive it as much as I used to. Link to comment Share on other sites More sharing options...
Buzzman Posted May 1, 2012 Author Share Posted May 1, 2012 The numbers were going in the extreme negatives and positives just as you had suggested. I told the dealership and I'm waiting now. Link to comment Share on other sites More sharing options...

StoplightAssassin Posted May 2, 2012 Share Posted May 2, 2012 Can you feel the car surging while cruising? Link to comment Share on other sites More sharing options...
Buzzman Posted May 2, 2012 Author Share Posted May 2, 2012 I didn't know what surging was until yesterday but after I went out for a cruise with a few friends of mine I definitely noticed the car surging. Forgot to repost here. Link to comment Share on other sites More sharing options...
