Thanks everyone for help i will check off each and every items advised here p.s. U da man, 1999Porsche911 :notworthy: are you a mechanic??? u seemed to know our cars very well. :thumbup: again, thanks for sharing your knowledge i will pick your brain later for sure, time to time, hopefully not too often :cheers:

will double check on all connections and gas, oil caps tonight thanks much on the disconnecting the MAF tip, that makes sense!! little confused on your direction, I should clear the current codes first, then disconnect the MAF, then crank the engine and idle a bit, then read the codes again?? Is it safe to run without MAF? Sorry if it is a stupid question as i am mechanically-challenged.

so i guess i have to take her to the dealer since i have no way of checking all those you've listed Jon

Hi everyone Merry Christmas, it's been three times in past several months that my check engine light came on. First time, dealer told me that my O2 sensors are going bad and cleared the codes. It came back on after several weeks. I called my dealer and scheduled an appt. but it disappeared before my scheduled appt. So i didn't take the car in. Few days later, came on again :cursing: right after i filled up the gas tank. So i tightened up the gas tank cap and it went away the next few days. A week passed, it came back on :censored: so i went to the Autozone and borrowed the OBD II scanner and came up with these codes P1123 and P1125 which were the same codes from the very beginning at the dealership, i think ( i was in the bay with the tech). I cleared the codes. BAM!! yesterday, it came back on :angry: Sorry guys for such long blah blah, but bare with me for a bit. I searched the forum and found out that others were having similar problems but mostly with MAF. Some claim O2 sensors were installed but lights came back anyways. So Loren, or anyone with similar episodes, my question is Do i bite the bullet and replace the all O2 sensors first, then MAF, then oil separator, then bellows tube, then DME, etc.... Guys! i don't know where to start, seems that dealers can't pin point the problems either. i don't want to start the process of guessing elimination at my cost either. If i go to autozone and get the same P1123 and P1125 codes again. What is my next logical step besides taking her to the dealership first? I've already checked for any leaks in any hoses near the intake. I do have cat-back B&B exhaust. Could this be one of the problems?? I don't have any intake systems of any sort. thanks in advance for any inputs, advises Jon p.s. my car is a 99 C2 with 50K miles i have no driveability issues, perfect idle, runs thru RPMs fine, runs no diff. from when the celis is on or off

thank you very much you guys for quick replies our manual asks to start with the 'tongue' of the tool facing the rear of the car then rotate so that it points front of the vehicle, this process will UNLOCK the assembly well, i was careless and did not read the manual carefully the first time around and just rotated the tool numerous times in circles hoping to hear a 'pop' or some other unlocking click. now my question is, 1. i don't know where to begin now that i no longer know my 'starting point' 2. when i turn with the tool, i get empty turns almost as if i was turning a stripped bolt, could i have stripped the locking mechanism by rotating it randomly as i did in the very beginning ( how stupid :P )? thanks guys but any help is really appreciated Jon

Hi a newbie here with a 99 C2 i read the manual and search the forum about process of removing headlight assembly but i can't seem to do it :( i get that tool and turn it as indicated in the manual but headlight does not even budge a bit i get empty turns my questions is does headlight suppose to pop out as you turn the tool (under some sort of tension?) or do i need to pry it out? help, help :help: :help: thanks for any inputs Jon
