that should do the trick... post the codes here.

so today i got a thermostat sensor and coolant sensor i installed em but after i cranked the car my engine had a super rough idle.

i messed with the thermostat sensor connection a bit and then right after i tried to crank it again my main relay started buzzing.

is that an indication that i fried the main relay and once again my check engine light is off and the car will crank but not start

turns out that it wasnt the main relay, its still good. i redid the ground again and it started up but had rough idle. adjusted the idle screw and now the engine runs buttery. no more troubles
