Hi everyone,
When cold my car starts to misfire after 10 min or so I stops. I changed fuel filter, fuel pump, replaced cps and wires and plugs
it runs good has power Im going to get my injectors flow tested and balanced.
any ideas are greatly appreciated. .

Fuel air or spark. Without one you get a miss fire.

Also a bhg could effect things.

would not not think a BHG on this case i change the oil every two months and same with spark plugs and with the wires.i was reading the TSRM after changing gears i would get and explosion at my exhaust.i Just replace my Maf sensor i was using a lexus with a 7mgte housing.

I double check my fluids mostly everyday i drive from costa mesa to santa fe springs everyday. Coolant is always on the same spot, oil has no contamination of water in it plus i use a bigger filter and i add 6qt of oil every time.I have a felling a set of coils is getting messed.
