I will check with MAF sensor with durametric. My throttle body and ICV are spotless. Considering that I do have a extra secondary air injection valve- would it be worthwhile to replace it too see what happens? Also, would I possibly get these types of symptoms if I have the vacuum hoses hooked up wrong? I will also check to make sure that all the vacuum hoses are still hooked up and didn't come undone. Bottomline- Can a problem with the secondary air injection system (either valve, hoses...) cause a car to idle slightly rough?
For about 1 year I have noticed that after my car is warmed up, idle seems a little rough. If you pay close attention you feel an occasional very slight shudder- similar to when a engine misfires. I hooked the engine up to my durametric system and it does't appear that I am getting any misfires. It didn't seem to be causing any issues so I just left it. I then put cat bypass pipes on and the idle issue became much more apparent. Sometimes the rpms would fluctuate siginificanty and seem that the engine was about to stall. I did have a CEL on however I thought it was related to the cat bypass pipes. I do not remember all the codes that I got back then but I do remember a P0410 and a bunch of O2 sensor codes (probably from the bypass pipes). I then took the bypass pipes off and put the stock system back on. The engine has been running fine however I am getting the sight shudder that I was getting as mentioned at the start of this post. After about 1 month of driving, I got anotehr CEL- p0410. I have read all the post I could find about this code however I really am not understanding the problem. Could a secondary air injection system problem cause the idle issue? Also, where should I start in trying to fix this problem. I do have a known good secondary air injection valve left over from a previous car. FYI- In the past I did change the AOS and I may have screwed up the vacuum hoses (I am pretty sure that I did everything correct but I may have screwed thngs up). I do not know if this could be related to the code or idle issue- the only thing is that I had the idle issue prior to the AOS problem. FYI-my car is a 99 c2 manual- basically stock.
I have a bad left rear ride height sensor on my 04 ctt (PASM). I can't find the part number. Due to wear, I cannot make out the part number on the sensor on my ctt. I am not sure of the exact name of the sensor. I have also seen them referred to a level sensors. Thanks, Steve
I have searched around and couldn't find an answer. My 996 has about 78k miles. I have had a ticking noise from left side of the engine. Checked the EGR valve- not the cause. The ticking is present at all times- hot or cold. Speeds up when engine is rev'd. I have tried different weights of oil 0w-40 to 15w-50 and the weight has not changed the ticking. The strange thing about the ticking is that about one year ago I slightly overfilled the oil during an oil change and the ticking went away. I thought that maybe it was the weight that I used (15w-50) so I used 0w-40 the next time. I filled the oil so the level was between min and max and the ticking returned. I then overfilled it slightly again and the ticking went away. I drove the car for about 1/2 year this way without the ticking. I changed the oil a few weeks ago and filled the oil to mid level (I was having episodes of massive smoke when driving hard due to the oil overfill). Now I have the ticking again. The ticking is quite loud and very annoying. I am very familiar with lifter ticking noises. This is what the noise sounds like however it is quite loud, I do get normal lifter noise on the drivers side. I have thought about this quite a bit however I cannot figure out why the tapping resolves when the oil is slightly overfilled. I can live with the sound however I simply am trying to find out if there is something that I should be worrying about. The car drives great and I would like to keep it that way (without spending any money).
tornik550 replied to Caguy's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)In my opinion, the best mods for the money is removing the helper spring on the clutch pedal. Gives the clutch a much better feel. Takes about 10 minutes. Cost=Free! I have modded my car quite a bit and my absolute favorite is the PSE mod. Not too expensive ($75 at my local shop), makes a big difference.
I have been changing my AOS. Everything is going well except that I am having problems getting the vacuum hoses hooked up properly. My car is a 1999 C2. I have several hard plastic/rubber hoses however I cannot figure out where a few things are supposed to go. From the check valve (the one above the alternator)- I have two hoses coming out- one comes out of the check valve via a rubber elbow connector, the other tube is about 1.5 feet then it connects to a + rubber connecting piece. I cannot figure out where the hoses coming from the + rubber connector are supposed to connect too. The four points of the + rubber connector are as follows- 1.- tube going into the + connector from the check valve (the one above the alternator) 2.- One of the tubes coming off the + connector has a round white/black piece then a hard hose- I think that this connected to the front intake connector butterfly valve (I remember this from when I removed it 3.- one point on the + connector has no tube 4.- broken tube (appears to have been broken prior to my work due the dirt) I realize that two hoses are supposed to connect to two intake connector adapters (I already have the one on the righ side of the car connected as it comes from a different location) I am in desperate need of help. I have been searching for quite a long time and have not found any answers. I have also search my shop manuals and also didn't find any info. Thanks, Steve
I am in the process of replacing my AOS and I have run into a few snags. I have encountered a hose clamp that I cannot get off. The clamp runs the entire circumference of the hose. On one end the clamp forms a triangle. It appears that you need to spread the triangle however I am not able too. I have seen references in the past to similar hose clamps. People have mentioned that it is easiest to cut the clamp and install a worm clamp. I realize that cutting it off would be easy however I would prefer to remove it without cutting. Anybody have any idea of how to remove these clamps?
tornik550 replied to bigmds's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Chainsaw. Just kidding. There are four bolts. One on each end of the lower seat rail.
Thanks for the reply. I took off the sensor, everything looked fine. The connector was connected properly. Does anybody know the part number and the correct name for this item? Thanks
I started my 05 CTT a few days ago and the "air suspension faulty workshop" warning came on. I had garage door problems so I had to park my cars outside overnight. It rained quite hard. I have played around with the air suspension level and also the suspension ride setting and everything seemed to work fine. Tonight, I hooked the car up to my durametric reader. Under the level section, there was a warning that said faulty left rear level sensor. I tried to clear the fault however I was not able to. Can anybody tell me where the "level sensor" is and also how to determine if mine is actually faulty. FYI- I have had the CTT in the garage for the last three days- completely out of the rain. Also, could anybody let me know what thr part number for the level sensor in question. thanks, steve
tornik550 replied to nirel's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I have not personally used this product however I have seen it mentioned in the cayenne section. I would take a look there or at rennlist's cayenne section.
tornik550 replied to Caguy's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)PSE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Also, sugar in the gas tank to feed the horses so they can make more horsepower. just kidding.
Are the rotors on Cayenne Turbo's the same size as the Cayenne S? I specifically need rear rotors. I see references to rotors for 18" wheels and 17" wheels. Would my turbo need the 18" size? Very confused.
I have a set of MODA 220 wheels on my CTT. They look great however I do not like the center caps. I took the center caps off of my 996 and tried to put them on the CTT however they do not fit. Does anybody know where I can find new center caps (preferably with the Porsche Logo) that will fit? The measurements are below- Stock Porsche Inner Diameter 59mm (2.32") Outer Diameter 76mm (2.72") Moda Center Caps Inner Diameter 68mm (2.68") Outer Diameter 74mm (2.91")
does anybody know if the license plate bracket for the s and turbo are the same?
