i just recently got tuned the other day and now i am having problems with starting the car when hot.
first off the car is an LSvtec turbo in a 91 civic. running a p72 with S300
when the car was getting tuned it would have problems starting and the tuner couldnt figure it out, the car would crank but not fire. it would have to be cranked a few times for it to catch then we would have to push the gas so it would stay idling. when we do get it to start when hot it idles very lean and wants to die some times it does die righ away when hot starting it or after driving around for a bit it will have a lean idle. Now on to the cold start,
When i start the car cold it fires right up and idles, but it idles kinda low and very rich like 9.5/10 AFR after a few mins of it idling it will idle around 900 rpm and have an AFR of about 12. The car runs and drives fine other than this.

 

Don't even post up here. Take it immediately back to the tuner. As soon as you noticed the problem you should have at least called him.

 

so this sounds like it has to do with the tune its self then? ill take a data log of this when i get home so i can show him because litterally i got this tuned last wends and havent touched a thing that would cause it to do this and it was happeing the day i brought it home with the hot start issue. he couldnt figure it out. or just didnt want to take the time to

 

I'm going off of the info you gave; "after tune". Sure sounds like it.

 

Ok I can also post up my tune here in a bit as well

 

No. This isn't the forum. Plus you need to take it back.
