1G Idle Surging and When hit gas dies HELP!

[nodaysoff92]

92 Talon tsi Big 16G i was out doing some pulls. Later that night starting dying was sure it was a boost leak. I actually installed a bigger new FMIC. i redid piping a ton of times and blt.

If couplers are in funky angles or something will it die?

So far people have been telling me all sorts of things it could be

02 Sensor?
Maf Sensor Turned around or not plugged in?
Idle Speed Control?
EGR blocked?
BOV recirculation?
Time for Tune since new intercooler???


So i certainly clueless. It starts right up idles drop and surge up losing about 50 rpm every half a minute down to low 360 or so rpm.

Im about to go check it out from easiest on down to hardest.

First off is just checking the MAF sensor.

How to see if Dirty and arrow should be facing towards the rear of the car on my GM MAF correct?

any and all input is much appreciated again its a big 16g all supporting mods. GM MAF.[DOUBLEPOST=1407698316][/DOUBLEPOST]UPDATE more than likely it is my MAF.

I unplugged it and plugged it back in and car starting acting even weirder.

my boost controller also says my injectors are running at 90% on idle and then starts going down as rpm increases is that normal?

Could be the MAF defiantly check it to make sure it looks fine, also. I know this sounds silly. But think outside the box. Make sure it's not a fuel pump, I've had my share of vehicles and I know that Chevys need 65psi of fuel pressure to not only run. But keep going. Any less and it will cause the car to choke up and act stupid. So do a pressure test of that, pull the line, start it. Check that it had a good flow. Go from there!

Alright thanks I'll get out my manual and check that.
