I have a stri oil pressure gauge in my evo and all of a sudden it started going crazy. when i drive it goes from 60 to 80 back to 40 up to 80 then when i push in the clutch and just idle it sits at 90-100. could this be bad oil pump or just bad connection(hopefully). also when i hit bumps it goes up and down. the needle will move when i slam the door kinda hard to. please help.

 

bump!

checked your sending unit?

 

my STRI EGT guage does the same damn thing.. ill be driving normal, goes up to 2k, back to 400, then up to 1500, goes normal, then completly shuts off and just the needle is lit.. i took it out the other day and just pushed reall hard on the back of the plug and hasnt done it since..
