Otto's adventures w/2003 S

[Ottomotion]

second test an hour and a beer later...
Car idled for 5 minutes.....no deviatiion.
Ran the revs up to 3000 rpm for 5 minutes...no deviation

did several revs up off of idle to 3500-4000 and let back to idle when it finall started showing a p1341 again. This time Cam 1 -0.89 and cam 2 1.28

Still no CEL

What are the allowable deviation values and could it be I am within them?

Otto, I believe that in order to get an accurate cam deviation reading you should drive your car for at least 20 minutes to ensure it is properly warmed up.

I've read elsewhere on this forum that deviation numbers up to 7 are "acceptable". Anything over 5 though, should indicate a problem.
Your numbers seem just grand to me. Considering the imperfect way the cams are driven.... it's amazing we can get THAT close, honestly.

Well...I had to go on a test drive :dance:

I have logged 30 miles and temps are holding well.

Deviations are as well.....
Cam 1 -0.75
Cam 2 1.28

...and they have not really moved off of those numbers. I think getting the car warmed up and in proper operating temps was important.

Still no CEL

I wonder if they ever came from porsche with dead-on numbers?

Thanks for the input!

Going to try for a smog cert tomorrow....
