VS Problems - HELP!!

[Chappo_1]

lol what's the thermostat got to do with it??

+1 for coils, plugs, leads - they can cause a thump if the spark is crappy. do you know how old your plugs/leads are?

+2 for coils, plugs and leads. My VS was doing something similar when I bought it. I put in new leads and plugs and the problem went away. Relatively cheap to try. If it doesn't fix it, you really haven't lost much.
