CEL, orange maintenance light, and wont rev past 3000 rpms!!!
I bought the car like this; previous owner says its the o2 sensor. Happens randomly. I had advanced auto reset the check engine light, car ran great for I dunno, 2 or 3 days. Then the CEL came back on, and the orange maintenance light on the right hand side. Says "cruise control not working" or something to that affect, even though I can still set it on. But the car is very slow, wont rev past 3k rpms, and if you floor it it will hit some sort of 3000rpm rev limiter and just stop driving forward until you let off then ease back into it.
I suppose it def. sounds like it could be an o2 sensor, does this sound typical? The orange light goes on and off at random. So it doesn't do this non-stop.

Everytime I go to advanced, they come up with different excuses as to the code. The most recent time I went they said "motor is running lean, probably bad gas". Which could almost make sense since the previous owner drove like 1k miles in like 4 mos lol. But There is a thick hose that hooks up to the valve covers and comes out of the plastic cover to the intake or something, and the big round boot that hooks up to the intake is like almost torn in half. It still plugs up but it does have a big tear where it hooks up to the manifold.
You think that could be it?
I'll see if autozone can pull a code number today.
Why would this put a 3k rev limiter on though and not allow me to floor the car ?

I'm gonna guess..But historically, the problem ends up being in most cases a vacuum leak...The 3000 rpm or reduced power is called "Limp Mode"...allows you to get off the road safely with some power, without hurting the engine, should something be drastically wrong...If is a vacuum leak, there are a few common areas that harbor this problem, and are simple to fix.

This problem is mentioned quite a bit on the forum so see here for more info as its usually a very easy and cheap fix, if its a new breather pipe a new sturdier pipe is only £5 from a dealer

oh good stuff man thanks a lot. So the new piece the dealer sells is tougher than the stock one? I'm going to call the dealer up quick.. advanced cant get it.
Will this cause poor mileage? I've only gone like 80 city miles, and its used over a quarter tank of gas already.

If the problem is the pipe you can tape up the pipe as a temp measure until you get your new MUCH sturdier pipe.
Did this on mine and the MIL went out after 2 cold-hot cycles and the limp home stopped.

85_305, did you ask them to send that big boot as well? I think you are talking about that large rubber boot between the air cleaner & the MAF. The PCV hose should fix you right up as far as the lean condition goes but that ripped boot is going to let unfiltered air in there as well. If you have any hissing noise you may also want to do the IMT valve o-rings. All these vac leaks show up most often once it gets cold outside.

Did I ask them to send me the big boot? No I dont think so? Isn't that all connected? The Jag dealer said the PCV line is a very common piece so he had one in stock for my car. I would assume the pcv line comes w/ the big boot right? Since they are connected and all.
I hope this fixes my issue.. I'm at like 117 miles and half tank already ughhh

code p0171?? help!!
So my car is throwing this code up. The cel comes on and the orange light illuminates and says cruise unavailable. This limits the car 3k rpms and seems to idle funny when cold etc. The only thing I know to be wrong with it is the pcv is leaking like CRAZY. Could this be it?
