Misfire
Hey guys my 97 Mazda b2300 it keeps throwing a misfire on number three check engine light will start flashing but it's only sometimes and only at idle once I start to get it gas it smooths out fuels trims are almost perfect. Have confirmed spark, compression, fuel pressure and fuel injectors have been replaced recently 7 months ago. She will run very rough and is very sluggish when cold but once it heats up it runs much better I confirmed vacuum leaks/intake gaskets aren't leaking.
