How long ago did you replace those spark plugs?
I have some videos on here in which I tried to chase down a P0302 cylinder 2 misfire. Plugs were the first thing I tried. I even went as far as replacing the cylinder head. In the end, I had low compression in that cylinder which was only getting worse.
I HIGHLY recommend getting a compression tester and checking compression. I have a video on how to do that. It’s easy to do DIY and can help diagnose or rule out a real engine problem.
its a automatic
it was the p303. misfire in 3rd cylinder. that issue was fixed but now I’m dealing with not being able to drive steep hills
I tried Googling the P3303 code and came up blank. Is your car manual or automatic? Which engine? Did you change anything recently that might account for a difference in behavior?
Hi,
I have a 96 subaru legacy and in the past when I went up hill it threw the P3303 code. Turned out to be a spark plug issue. Now that its fixed Im still having issues driving up hill. Its like theres not enough power or gas to make the car go up steep hills.
Would the crankshaft or camshaft sensor cause that issue? I replaced the fuel filter and it made no change.
I have a Subaru Legacy GT 2.5, it acts the same way, but has a grinding noise,it reads as speed sensor A, and also O2 sensor. did yours have any grinding noise ?
I’m not sure what the numbers signify. The first one I swapped in was still finicky, but better. The second one I installed has worked perfectly.
Did swapping one of the other sensors fix anything? I went to the pick and pull as well and could only find speed sensors stamped with a 1.
I can see how you might come to that conclusion, but the smoking gun was jumpy speedometer. Based on Subaru factory diagnostic charts and wiring diagrams, I linked both that and the wonky shifting to the sensor.
I got some from the junkyard. The first spare wasn’t perfect. It solved the shift issue but not the speedometer issue (though it was LESS jumpy). The second spare sensor solved both problems. If this hadn’t worked, I would have considered heavier diagnostics.
I get the philosophy of this repair, but if you really want to see what’s up with the trans hook a pressure test gauge up to it. The behavior you describe sounds more like a weak 2nd gear servo, worn 2nd clutch, or a worn 1-2 accumulator.
The transmission is OK. I’m more than 90% sure. The speed sensors do govern shifting. The speed sensor, according to factory diagnostic charts, can cause the speedometer needle to jump (which mine does at low speed, NOT the tachometer, which behaves normally) and can cause erratic shifting (which I had at low speed),
There was no slipping, otherwise I’d be worried. The car behaves markedly better with the “new” sensor, (no transmission weirdness) but the speedometer still jumps a bit.
@MercedesDieselGuy do you mean the tachometer or the speedometer. If its having problems shifting gears then chances are those 1st and 2nd gear clutches may be toast. If that is the case which I hope it’s not then you’re best option is going to be a remanufactured transmission bc replacing clutches in an automatic transmission is a royal pain in the ass, and it doesn’t always solve the problem!
It was a bit wonky between first and second gear in stop and go traffic. After a few days, the new sensor I put in still doesn’t seem to be perfect (though it IS much better than the old one). Shifting almost perfect, but speedometer still not perfect. I’m going to swap for one of the other sensors I got and see if there’s any improvement this weekend.
I don’t blame you there. $100 is a lot to spend especially if you don’t know if this will fix it. is it just stiff shifting or does it have problems changing gears?
My issue was mostly price. A new one would have cost around $100, and there was no guarantee this would have solved my problem. Since these don’t actually go bad often, I opted for three of these (and a handful of other parts) from the local pick and pull for a total of $30.
There’s some Subaru pages and groups on Facebook that generally advertise a lot of mechanical parts and whatnot, some of the stuff even dates back to the 60s and 70s.
It was snowing, but not all that cold. Wet though. Wet and kind of cold. Pretty unpleasant now that I start thinking about it again.
I felt cold just watching your video.
