Sr20det cutting out into boost... Haaalp

[Ljensen11]

Just got done swapping my s14 with a s13 sr car has z32 fuel filter, front mount, walbro 255. But anyways I installed my fuel pump to fix the fuel cutting and ran good up and down the street did a donut or two now it runs like crap so I checked the plugs and they where at .042 lol so I put some hks plugs in there gapped to .032 but still runs bad but if I disconnect the battery it will run good one time up the street.. Wierd af anybody have any suggestions cuts out getting into boost almost like a maf but I don't think it's the maf. https://m.youtube.com/watch?v=j_4mmDeowqA

Tune maybe? Possible tps

Boost leak. With the upgrades you did it sounds like a boost leak. Start by pressurizing your system. Visual inspection is not enough.
After you have confirmed there are 0 boost leaks report back

what injectors do you have?

[Ljensen11]

Stock injectors

Every 240 owner, even if you own an N/A KA24, should be proficient at performing this leak test regularly.

Also, with a little experience, you can tell by the subtle surge returning to idle while the wheel speed is coming down, if you have a leak, or a loose wastegate.
This only works if you do not have a proper bypass setup, which most don't.

It's always been the following for me

Boost leak: check/replace all vacuum hoses/clamps/fittings
Spark plug gap (factory gap is .028 i believe, you're relatively stock, so keep it around there)
Maf condition: plug connection points/ wiring/ sensor cleanliness

Yup, do the easy stuff first, checking for boost leaks and connectors then we can move on to the more complex possibilities.

if you hear hooves, start looking for horses not Zebras.

coil pack going out is common and can cause a similar issue.. But you failed to inform us what steps you have taken since your initial post

[Ljensen11]

Checked the maf and also changed out all the plugs probably
Try to do a boost leak test tommorow

[vertsilvia93]

Mine does the same exact thing!

[Ljensen11]

Lol yeah it's no bueno

Now the car isn't revving https://m.youtube.com/watch?feature=youtube_gdata_player&v=WDBNUSXNfoU

Have you done the boost leak test?

If you haven't done the boost leak test, here's an easy way to do it.

I've tried using a bike pump and didn't get anywhere. Use a compressor.

EDIT: Make sure you block off the valve cover breather line from the turbo inlet to the valve cover. Otherwise you'll pressurize your valve cover, and it won't work. (That's just what I've read; if I'm wrong, please correct me.)

Doing the boost leak test this weekend

I need to try and do a boost leak on mine but it's been too cold here in Georgia

Boost leak test would only show if he is having a problem at boost. Since it's running like crap all the time its either a spark issue ( like timing too advanced ) or coil breaking up. I'm currently tracking the same issue but not as bad. About to throw some coils in if I can find some donors here in SD

Nah it shows all failing joints and tears in his plumbing. Missing vacuum plugs or cracked hoses.
