Default Can't exceed 42000 rpms.

I have a 98 outback manual transmission with 165k on it. For some reason now I can't get it to accelerate past 42000 rpms. When it hits 4200 rpms it just won't go anymore it sounds like it revs a little higher but my acceleration tops out, and I have to shift into the next gear to continue accelerating. Doesn't matter what gear I'm in as far as I have messed with it. I also have problems with my car occasionally dying although this happens very rarely. Any suggestions on what this would be would be so helpful. Thanks so much.

Sounds to me like either a ECU issue or perhaps the fact that you are trying to get the car to go about 36000 RPM's past the redline...

limp mode wouldn't let you even get up that high. Does sound ECU related though.

I bet you could get a job with an F1 team right now if you could show them how to rev a car to 42,000rpm!

Vehicle Speed Sensor is probably on its way out.

look at the speedo when it happens, if its fluctuating you found your problem.

Same thing happned to one of my 98 RSs.

ok so I'm glad one simple entry error could draw so much attention. hahaha. My speedometer doesn't work and hasn't worked for a long time I haven't had the codes checked, but the check engine light is on and when I had them last checked they were the P1507 Idle control system malfunction (fail-safe) and P1540 Vehicle speed sensor malfunction 2. I didn't know if either of these things would be related or not. I haven't got it checked out due to time and money but if I can't get this figured out I will. Thanks so much for all of your help. Sorry it takes me so long to get back but I don't have internet at home. Thanks again,
Bryan

if the acceleration tops out and reaches its top point where the acceleration rate will not increase, one of the reasons maybe the transimission fluid.

How many quarts of transmission oil does my 98 outback 2.5 litre manual transmission hold? I bought three quarts already and have just been waiting to have a night to let it drain all the way out, I will try to do that tomorow. The guy at NAPA told me that 3 quarts would be fine, but then a friend with an 2.2 litre legacy said his tranny held 3.5. I just want to have everything I need. I also have a friend who has the same year of outback and said that I can switch out my speed sensor so I will try that also. My biggest setback is that I can't do any work on my car in the apartment complex that we live in. Thanks for your help I will report back once I do these two things and see the results. If anyone could give me any helpful hints with either of these actions it would be greatly appreciated. Thanks for your help.

it holds around 3.5 - 4 depending on how much you drain out.

If you have the manual, it should tell how many quarts you need (Haynes repair manuals are nice to have around to, for little break-fix projects). Have you done any of the recommended maintenance? (rear diff changes, timing belt, etc). Keeping that stuff up will keep your car running longer.

On my wife's previous 95 outback (2.2L), the first owner had let the timing belt go 30k miles past recommended change time. We didn't know that, but every so often, the car wouldn't start, just turn over and over. 5 minutes later it would start fine. CEL would always come on, we finally got it checked out, and it was the crankshaft position sensor because IT HAD TINY PIECES OF TIMING BELT ON IT!

So yeah, getting those CELs checked and/or resolved is always good.
