Multiple misfire code 2004 civic 1.7

[Johnny w]

Car is throwing a multiple misfire code,at times it will run just fine. It always happens on start up.

Thanks in advance

I would check for a leaking Head Gasket. A lot of the Civics with that engine develop a leaking head gasket at higher mileage. The engine can leak coolant into the cylinders overnight and on initial startup it can "lean out" a cylinder causing the codes to be set.

 

be sure to check for a low coolant level in the radiator when its a cold engine. NEVER open a HOT radiator cap!

 

 

hope this helps
