Thanks for the feedback and advice. I am having this looked at, so when the verdict comes in I'll report the findings. In the meantime, I will check those pitot/static drains. To 'a' in NJ, no, I'm not familiar with the NJ Monney group. Where are you based? I tie down at TTN.

I have to go with Big Tex on this. IPAD mini and Foreflight.

Hi all, Flew from KESN to KTTN the other night in relatively warm (above freezing) temperatures. Nice flight, all instruments normal. Refueled at KTTN, but upon restart, I noticed the ASI reading about 50-60 mph (while sitting still at the fuel pump). Was concerned, as I have never had that indication before (I've had my plane for 6 years). Flew it again the next day. On start-up the same thing occured (temps still well above freezing-nice for January here); at the suggestion of my instructor, I applied pitot heat, and surprisingly (given the warm temps) that seemed to help. By the time we were ready to take off, ASI was reading almost zero when we were sitting still. On take off and climb out the ASI seemed to be functioning properly (airspeed was what I normally get when pitched for climb out), but the VSI fluctuated erratically, and continued to do so in straight and level flight (almost like we were hitting pockets of turbulence), but air was glass smooth. Altimeter reading was within +/- 200 ft of independent GPS altitude. Variations on this theme presented themselves throughout the flight, so obviously I'm having this looked at, but I thought I'd throw this out here and see what any of you think the problem could be. Thanks/Jeff
