ZC Very hard to start when cold
 

It will take a solid minute of cranking to start it when it is cold, then it will bog and die the first time it starts....second time is another long crank and runs great. if it sits for a few hours it will do it again. I just replaced the coil and cap and rotor cause the coil commited suicide. any thoughts?

i just cleaned my IACV it was NASTY so hopefully that does the trick i will see again in a few hours when the car is cold!

update?

Re:ZC Very hard to start when cold
 

no luck, still slow to start and when it gets going it bogs down......if you floor it when it is bogging it continues to bog and sounds like it is backfiring through the intake manifold....if that makes sense. however once warmed up the idle is awsome and runs much smoother now that i cleaned that thing! so i am ready for more ideas!

Re:ZC Very hard to start when cold
 

list of things i have already tried to fix this issue

cap
rotor
coil
plugs
plug wires

Well when it is cold doesn't it inject alot of fuel. If it does this and you injectors are dirty it could just shoot a jet of fuel instead of a mist. Someone correct me if I am wrong. So lets say that when your finally warms up the fuel that is coming in is cold and it meets the warm/ hot intake manifold it will expand making it atomize better but not like it should. Clean your injectors. I don't know how but with fuel injector cleaner. Worth a shot.

i didint have it on my list but i ran to tanks with fuel injector cleaner through it already. I was thinking that maybe i might need to have them taken out and cleaned?
