drive there is very little power, allot of hesitation, especially going up =
hills, but after 5 minutes or so, temp gauge needle gets to 4 o'clock, the =
car jumps to full throttle and has good power after that, like a sticky bre=

 vacuum leaks, just changed the temp sensor to the ecu (a problem you liste=
