So before I start in sure someone is going to tell me this thread is up somewhere and I should look harder but I have and nothing I found matched my problems. My car has recently been taking longer to start use to start within 2 cranks easy. Now it takes about 5 seconds to start it and it slowly rises to cold start idle. I replaced spark plugs boots and wires. Tested battery alt and starter all were good. But for some reason still takes a while. And I don't smell gas nor do I see any leaks so I don't think my injectors or rail is leaking. Especially since once the car is started it runs like a champ. Any ideas? I need help it isn't anything bad but its bothering me and I want it fixed. Thanks in advance.

 

E85? Speed Density? I have both of those and my cold starts have become pretty rough now that night temperatures dip below 40 degrees.

From what I can tell the tune can be richened up to address this. I might ask my tuner, but I might also just wait it out.

Try putting key to ACC before starting, see if that helps any.

 

No E85 or speed density car is pretty much stock just forge bov inked 3in piping and his catback. And I checked for vacuum leaks but didn't come acrossed any. I am stumped I was thinking maybe egr or iacv I'm not sure

 

How old is your battery?

 

is it cold there? i think it's the battery.

 

To be honest I'm not sure how old it is and I'm in Oregon it has been cold but it's starting to warm up the cold could have drained it a bit I'm not sure just about 35-50 lately. I guess I could test it again see if the cca dropped at all. But can't think of anything else it might be

 

Sounds like the fuel injectors are starting to clog up. Try one of these bad boys and see how it goes, worse case scenario your fuel system is cleaned.

You can purchase these from any Walmart or auto parts stores, don't use the other Gumout junks

 

You could rule out the battery if you have a starter box that has hi-amp for cranking. Put 200A on it and see if starting would change.

 

Well got some injector cleaner and tested my battery starter and alt battery was good alt was good but my cranking volts were 11.05? I'll try doing that tomorrow see if anything happens
