had a couple of warnings up on car since weekend which dont seem to be going away

18265 - load signl from ecu p1857-35-00
16497 - intake air temp sensor signal high
16486 - 16486 signal too low p0102 -002

funnilly enough both sidelights have blown recently as well just wondering if its at all related
i also cleaned the maf filter at weekend as car didnt seem to be runnign right but no error codes

have had funa nd games since then

anyone with any similar experiance
