Default lots of problems!!!!

Okay guys (and girl) first off my cluster lights and seat control all went out I checked the fuse but came up with nothing(it was good) second my heater where it shows the temp. it flashes and I don't know why but it is just the numbers.. I am still having problems with the service emgine soon light almost everytime I start it it comes on but sometimes it does not.. and sometimes when it doesn't and I take off hard or hammer down on it it kinda spudders and cuts out and then it comes on... any thoughts?

Have you done the BASIC tune-up...AS for the flashing TEMP...that indicates that you need to re-charge your A/C with freon....

how can it run out without being used? yes I have done a BASIC tuneup like plugs, wires, oil, filter, haven't got into the sensors though.

1) Get the stored error codes out of the ECM; that'll tell you what your flashing Check Engine light is trying to tell you about

2) The blinking temperature digits on your HVAC panel (which presumably stop blinking after the first two minutes of driving) are telling you that the automatic climate control system has detected a fault of some kind. It'* most likely low on Freon, as someone else said. There is a separate procedure for getting its own error code (separate controller not related to the engine or Check Engine light), but if the system seems to be working okay other than maybe not blowing cold A/C (which it also uses for windshield defogging), low Freon is probably your only problem there.
