ok guys she is acting up it started after I gunned it a little in the rain and now is sputtering and giving me 0302 code....... anyone? could that be the O2 sensor?
ok I had a leak test done , a new spark plug a new coil a new injector, the only thing I haven't replaced if the O2 sensor so that kind of narrows it down. Is there s front and a rear O2?
Need more info of the whole story (how the car got into this state) and the cone filter, which may introduce vacuum leak.
ok about a 1 1/2yrs ago the car started to throw the same code 0302, like every other day, according to the history of the car this issue has happened before and the previous owner took it to the same Porsche dealer, so they were familiar with it. I researched it and I changed the coil pack and the spark plug, then it ran ok for several months the it did it again so I took it to the Porsche dealer ship and they performed a leak down check, also replaced the spark plug and coil and installed a new injector ( $$ ouch ), then about 5 months later it did it again I took it back to the dealer and they erased it and off I went, about 3 months later It was at a light (no one around) I launched the car and when I came to a stop the car started to shake and the 0302 code came back, I have a scangauge in my car so I managed to erased it and the car drove a little better, if I baby the car the code doesn't come on at all but if I gun it or launch it from a dead stop it automatically throw a 0302 code, so far in 2 yrs that I have had the car I have seen 0403 code twice, I think that was the catalyst converter, but that was on a couple of long drives. I have put the Original air box back and it still does it, I run 93 gas, and all my oil changes and coolant are up to date. this gremlin is really getting on my last nerve.....
I knew it can't be that simple I think O2 sensor is unlikely as it controls the whole bank. I don't have much to offer in this case. If compression and leak down check out on cyl #2, I wonder if it could be a sticky intake variocam+ lifter. Just a thought. That doesn't explain why the new coil and plug seemed to fix it for some time though.
If I baby the car I can go months without a code but the min I spin tires or launch it from a dead stop thats when she acts up.... and the code spears someone told me these cars were made to be ridden hard.. lol this has been going on for some time any info would be GREATLY appreciated.... TY in advanced.
Seen this once when I first bought my car a few years ago, but it went away after some longer distance driving, the car has been fine the last 4 years, so I'd say nothing to worry about given the short drives you do.
if that was my car, I would bring her out for a good, hard, long run. With fresh oil. drain the oil and repeat one more time.
I'd run it hard and let it heat up and keep it hot for a while. Most if not all of the moisture junk will go away, and the rest will go away after another drive.
