Yesterday on my way home from work, check engine light blinked for about 15 seconds then turned off so I took it to auto zone. It came up P1399, random cylinder misfires. Today on my way TO work my check engine light came on and stayed on. Took it back to auto zone and it spit a P0113 code, intake air temp sensor. Could these problems be related and if so, what should I start with? If not, what should be done. 1999 civic lx 1.6L.
