Ok guys, my tps is set perfect, egr and iac are both cleaned along with my throttle body intake and mass air and my car still stalls out when I start it in the morning. I hold about 1200 rpms for a minute or so then it is fine, what the h*ll could be causing this problem???

 

my car used to the the same thing with my old engine..i thought it was just cold nature but when changed the computer and maf..it stopped...does your car do it all the time or only cold start ups?

 

VACCUM ISSUE!

 

Did you just do the H/C/I setup? You might need a custom tune if thats the case... Mine car did that untill I brought it in had a chip done. Your stock computer need to be calibrated to your setup, your A/F ratio could be off along with other things.

 

yes it is only on cold start ups, I did the H/c/i almost a year ago and didnt always have the problem.

 

is there an easy way to diagnose a vaccum leak?

 

there are different ways to check for leaks.. fogger but if u have a manual fan it will blow all over the place, electric fan make sure its off and the smoke should get sucked in.. or triple check all connections u might have over looked something... Get a can of starting fluid and lightly spray around suspected areas, idle will rev up if it gets sucked in...
