Lately my the temp gauge in my EF has been on the fritz, i keep thinkin my cars gonna overheat. It started off slow for a few days only raising from 1/4 way up the gauge and then start to rise to a 1/2 way mark,m and then as i would juggle the clutch and throttle it would go back down, and back up and back down and back up and i seriously thought it was a heat issue. Well yesterday i went on a long trip and it got worse, it would rise to almost the white line meaning its getting HOT, and rarely come down when i left off throttle to cruise. So i pulled over 3 or 4 times turned it off and let the fan run. I would sit for less then a minute, start it back up and temp was fine again?... but soon as i started moving it was right back to "HOT" again. I even noticed when i held my sunroof switch it would spike in temp.. which makes me think its not heat its got to be an electrical issue. The gauge responds to signs like when im boosting it goes up.. making it look like it could be a heat issue, but when i mess with a switch or my lights it also effects the reading so im not sure which way to lean.. My fuel gauge is also acting funny, i went to fill up the other day at about the halfway mark and it auto cut off meaning i was full so i turned on the key and they level stopped at the 3/4 mark.. Maybe some bad grounds in my gauge cluster? or bad sensors? Another issue is my turbo timer started acting funny about the same time the temp problem came up, sometimes it has no power and i check every wire to it making sure its all still soldered and nothing, then randomly itll be on when i start the car another time. Any ideas would help.. at least where to start looking for possible bad connections.
