HELP!!! temp. gauge messed up and it runs rough
I have a 1992 silverado 4x4..it has alot of miles but is still running strong..a few weeks ago the temp. gauge went from 0-260 with in 5 mins but then it goes back down and then back up..its not really running hot so i replaced both sensors and replaced the ground wire to the sensor on the intake..after i did this the truck wud idle about 1500 and the service engine light came on..it wud idle back down but when i put it in gear it wud almost die and then sputter when i take off..im tired of guesing and replacing sensors that dont fix anything..the problem is getting worse and now when i rev it up it almost doesnt want to idle back down

What she said... I'd also replace the thermostat just because they tend to go bad anyways.
If you find a solution let me know because for some reason my 92 has a faulty gauge. The truck runs fine and everything, but my gauge doesn't move once the truck is running. It goes below 0 when the truck is off. then when it starts it never gets above 110. I replaced the thermostat and everything is working fine, but the gauge just isn't reading correctly.

the first thing i did was change thermostat..i replaced both sending units and thats when the check engine light came on so i had it hooked up to a code reader and it didnt read anything..i replaced one ground wire but i cant find any others (i hate electrical) like i said the check engine light didnt come on until "after" i changed the sensors..sometimes when i start the truck the check light doesnt come on for a few mins..other times it comes on instantly
