hard to start, idle problems, pressure drop
 

So i recently just got my car running and am having trouble with my start up and idle. it will take a few cranks to try and start it and sometimes having to jump the battery. but even when i put a fresh battery in it still took a few trys to get it started. it will idle really low around 400 rpm and shoot up and then idle low again and keeps doing it untill i drive it a little then it will settle and idle around 550-800 it varies from time to time. the vaccum will be all over as well when it idles. also when i am driving around and let off the gas it will go real rich for a second and if i stay off the gas it get really bad pressure drop.
i have a MS1 with V3.0 board. One thing i could possibly think of is that my battery has been dead so not sure if that is throwing off the start up?

Any one??

Could you post an MSQ and data log?

Also, there is no V3.3 board...

my bad i got it edited, for some reason keep thinking its 3.3. yes i will post my MSQ and a data log after work. i have been auto tuning with VE live and it has helped some but at certain RPM everything with vibrate pretty bad and the RPM gauge and Temp gauge jump around.

heres my MSQ and a datta log from today..... also note that i am having extream idle issues it randomly with bounce up and down then idle real low then back up again and then get steady, and sometimes when i start the car it will idle very very low and want to die then shoots up way high

So just took the car for a drive after it cooled down and it was running good then all of the sudden when I would go WOT it started to run super rich and just dump fuel, and while cruising when I let off the gas after the BOV went off it would go really rich for a second. Idk why it's doing this when earlier today it was running perfectly fine Some one help!

Looks like you're dumping way too much fuel in acceleration enrichment.

Battery voltage is rather unstable. Where is this one grounded?

The log also seems to be missing a few patches of time.

That's all that jumped out at me.

In acceleration enrichment I was on mapdot and had it on in boost. That could be why I was so rich, I turned it off in boost and took another log of my start up and of some driving.

My battery is ground in the trunk. My battery could be going dead I have been having to jump start my car,

As for the log missing parts I'm not sure why it is
I'll post up another log here in a bit

here are 2 more data logs and an updated MSQ small changes were made Attachment 54334

Try grounding the MS to the cylinder head or engine block instead of the battery.

My MS is grounded to the stock ECU ground. i thought you were asking where my battery was grounded.... but the RPM and Coolant gauge jumping around has stoped after adding an exhaust. so bassicly the only issues im having now is the start up. it seems like i have low battery or something is not right, it takes a few cranks to get it started sometimes having to jump the batter will start it up right away but my idle will be super low and want to die then just shoot right up then back down and just keeps doing that untill warm. after i drive it the idle will be fine.
