Hello all,

My 2003 Liberty has been misfiring with a blinking check engine light on start, but once the temperature gauge hits the quarter mark and I restart my car the misfiring stops and the light stops blinking but it stays on. I have replaced the spark plugs, ignition coils, and the ASD relay. Any idea what could be wrong?

Have you pulled the codes associated with the CEL? There are a number of things that could be causing the symptoms you're seeing, but without knowing which codes are being thrown it's a crapshoot as to where to begin troubleshooting.
