maybe check your grounds??

The 2 grounds by the battery I redone, moved battery to back, there is 2 grounds back there as well.

So I fixed the no start, I had the battery unplugged over night, put the other aic in. Starts fine now. Has a vacuum leak near the intake, which of course I cannot pin point. Was idling perfect, messed with the cold air intake and it started idle surging again. Unplugged the maf, idles fine but bad throttle response, changed maf to other one I had, still surges when plugged in. Another issue with car, is while driving around block if I ease into throttle it's fine, but when I go to give it more than 1/4 throttle it acts like it misses. Please help

This was before I messed with the maf

You will want to fix the vacuum leak to start with.

Fixed the vacuum leak

You said you have a vacuum leak around the intake? How are you determining that?

One vacuum leak most people miss is injector o-rings.

By ear, I've done the brake clean spray while running. I didnt go anywhere near the injectors. My boost gauge is reading 17 on the vacuum as a constant. Don't know if that helps or not. This is my first turbo and first dsm. So I'm new to these cars but not new to turning wrenches. This car is weird, I checked and adjusted tps. Did the whole .63 reading, adjusted thr throttle cable, started it, everything was great, took for a 3 mile ride. Pulled hard, no issues, I didn't stomp on it, just a 1/2 throttle to 70. Shut it off, and now runs rich, has a miss, back to square one. So I took the iac off, checked the reading, I am pulling 39 on all 4, I know should only be 30, I have another one on the way. Put it back in, started car, idle surge, and while the car idle surges, I have great throttle response, doesn't miss, nothing. Shut it off, start again. Runs for a couple seconds and dies. Unplug battery, start again, will stay running, but will run really rich, misses, stutters, cant get car over 5k

Things to check: leak in piping between the maf and turbo inlet, piping between the throttle body elbow and the intercooler, adjust the biss screw to get a good idle.

I was reading and watching videos on what to do next . Figured I would take the throttle body off and clean it up, set the tps again, then go to the biss screw. But I'll do a BLT before I go any further, just to double check no leaks. I was also pondering to delete all unnecessary vacuum lines. Any suggestions. I'll update tomorrow after I get this finished

Did a BLT, had a small leak at j pipe. Deleted all unnecessary vacuum lines. Cleaned the throttle body, reset tps to .63. Fixed exhaust leak. The only thing I didnt do was adjust biss screw. Cold start....idles at 3k then drops to 2k with idle surge, warms up to operating temp. No change in idle....shut off, restart, idles at maybe 1200 but will die within 2 seconds, will continue to die until I unplug battery, restart without a problem, will stay running, but now runs I'm guessing really rich as I can smell gas, stumbles when hitting throttle, just runs like dog shit. Oh and while cold, will run like a raped ape. All this is in park, not driving down the road as I dont trust it to bring me back home. Just pulled the ecu, nothing wrong with it at all. The car will start like this every time. Cold=perfect Hot=crap. Any help would be great

The car runs rough when hot even without the MAF?

Runs worse when I unplug maf

Replaced the o rings on injectors, and just put a new o2 sensor in. Still same thing, I'm running out of ideas
