sliderr

Hi i had simulair problems and I replaced the AOS (altough it was not smoking) but this solved my issue!

I had also this problem a lots of time almost a year ! - finally I decide to replace my AOS and my Air Sensor (not sure what the English word for it is) but its where the air comes into the engine... this resolved my issues and it drives like a rocket now.. be sure to replace your AOS with the 04 model which are (apparently more reliable) ..

The o - rings on the AOS both sides and on the throttle-body where gone, this was causing major vacuum leaks ..

Just got it back from the dealer, also the airsensor has been replaced its running smmmooooooooooooooooothhhhhhhhhhhhh :) special thanks to JFP in PA !

There she goes.....

OK - report from the garage, big vacuum leaks around the o rings caused the problems, also the Air Volume Sensor? was faulty not sure yet if there is catalyc converter damage but it seems to be ok ....... :eek:

Well I followed your advice, checked the o2 sensor but it was dry and there were no signs of rust or oil or anything really, so just to be on the safe I let my car pickup and tow it to the dealer today, when it was riding up to the truck it was burping like crazy... to be continued..

You mean i Will have to check The 02 sensor behind the cat ? I will do this tommorow morning first thing, if it can not be fixed can I drive it ?

Alright i was lucky i had the cable in my car and was able to find the software - looks like the 02 sensor on the back is bad? how is that possilbe it has just been replaced?

Mistake #1: Blinking CEL means pull over, shut the car off, and have it towed to the shop; something more serious has occurred.

Mistake #2: Never, repeat, never disconnect the battery to clear a blinking CEL; in doing so, you have lost all the critical diagnostic information pointing to what is wrong that was stored in the DME. Get the car towed into a shop, get it scanned.

My cel is now not blinking anymore, can i still drive it back?

Without the codes, any supposition as to what is wrong is purely a guess....................

All I need your advice, i have a history with my MY97 2.5, i had regular problems with my CEL turning on and I got teh 1126 ( running lean / rich ) or problems with my oxygen sensors before and after cat, and i had some problems with oil leakage on the engine...

I replaced the AOS ( with the .. 04 model ) replaced al my O2 sensors and air sensor.. When i replaced the AOS last week my car stopped leaking oil which is great news, however it did not resolve my issue as the CEL came back on after 300 miles...but this is what happend today !!

I am driving up north about 400 miles (my sisters house) and when I was almost there I did a few over-takes with high RPM's after this, my car didnt want to accelerate and it almost stalled when driving it, when i released the accelerator it stalled when going idle and i had to keep it on 2000 rpm to keep it running, also at this time the CEL was blinking and i lost all acceleration power.., I pulled over and reset the computer by disconnecting the battery but that didnt resolve the issue, although it is now running idle again but very rough and not shutting down.. the CEL is now blinking on off sometimes it does it and sometimes it just is " normally " on and at least i have some acceleration again ...

My question as I dont have any tools with me, can i keep driving it back home (400 miles) ? it seems to be handeling pretty normal again (at least driveable) but i am afraid of the blinking CEL which appeared earlier..

Does anyone knows the part number of th gasket ( # 16 ) Is there also a database where all part numbers are easy to be found?

thanks!

Loren do you know if I should i buy a right or left battery?

The normal Boxsters got a 70 AH battery while the Boxster S got an 80 AH battery.

Hi guys, i need to replace my battery what kind of battery can the boxster handle? i was tempting to buy this but i am not sure about the AMP/H and the Right or Left (not sure what that means)..

Thank you!

JFP any idea why the oil is on top of my engine?

If it came off easily, you are fine.

Hi guys, i tried what you advised, with a warm running engine i removed the oil cap, when i removed it (easy) i heard a lot of sissing from sucking air into the engine (i guess), is this normal, also it resulted some smoke coming out of the oilcap gap? is my AOS bad??

Normally, a bad AOS will have an unusually high vacuum in the sump. Try removing your oil filler cap with the engine running, it it is difficult to get off, you have a bad AOS.

Thanks for the respond, i am tempting to replace the AOS, but i was reading that a faulty AOS was combined with a lot of smoke? as i dont see any smoke coming from my car...so i wonder if..

Guys my MY 97 boxster was i thought fault free after replacing all of my o2 sensors with new (Bosch) ones, replaced the MAF just starting driving it again and again I get the CEL ... any idea's?

codes p0140, p1125, p1123 and p1117 ..its driving me crazy!! Also i just opende up my engine compartment and i saw oil ON TOP of the engine, how is this possible? I know the dealer replaced my oil return hose but is this broken again or is this to less info to diagnose this? I know i have to replace my IMS or RMS already...nightmare!

My response was directed to member "sliderr" because he only has code P1123 on one cylinder bank, what is clearly a different problem. Vapour lock is very rare under normal driving/temp. conditions, the problem will sit elsewhere i think.

RFM how can you tell a injector is bad or leaking? is it worth wile to buy this will it WORK?

I've Seen all 4 1123, 1125, 1128 & 1130 Lean and Rich Mixture messages for both cylinders 1--3 abd 4--6. I haven't checkd to see if it's logged any lately because the check engine light hasn't come back on yet.

did you already replace the altenators?

I have exact the same problem i gave now replaced all altenators maf o2 sensors (all) still checked vacuüm on the engine still i get code 1123 :(

I hate to tell that I don't know what a CEL is.

Man I wished i could say the same !

And how old are the tires...from date of manufacture.

Tires are continetals (orginals porsche) they are a year under they car, (drove 15k now)
