recently ive been having cold start issues, car will start sputter and die if i dont give it a little throttle, if i let it die it starts up 100% normal the second time

at first i thought that i got bad gas but ive gone through 2 tanks of gas and no change. ive check for vacuum leaks and fuel pressure it all checks out.

its not "normal" as a lot of people say with lnfs, ive had the car for 4 winters and its the first time its done this.

mods are catless downpipe, zzp intercooler and gms1. car only has 65000 kms on it.

 

mine did the same, then stopped, I changed fuel injectors, fixed exhaust leak, still same crap, I'm starting to think its moisture or something on spark plug from temp changes seeing as it goes from like -20 to -5 here and I'm in a garage that's around 8 degrees C I just give up lol

 

Send me ur tune tom I'll fix it

 

my tune is stock gms1, it shouldnt have gold start issues, lol, ill send it to you tho.

 

Sure no problem happy to help

 

How old are you plugs? When my plugs started going (would get 10-20 misfires on a 2nd to 3rd gear pull) cold starts around 0C to -10C it would sputter and struggle till it warmed up a bit. Changed them out an problem gone

 

Check all of your vacuum lines. Check the Evap Purge selenoid on the manifold.

Make sure your plugs are good.

Have your valves been cleaned?

 

vacuum lines are good,
plugs are newer, i dont think valves are the issue, car has 65000 kms

seems like with the few tweaks that KMO43 put in the tune it starts normal now, going to cold start it a few more times.
