strange hesitation problem

[iron bird]

Ok so my new found dsm problem. when i first start my car it hesitates after 2000 rpm even through boost. it happens when completely cold or just sitting for 5 min. did a BLT and no leaks, new plugs and wires, and new tps idk where to go?

do you have the maf translator setup properly?

I have a similar problem and here are a few suggestions I picked up. Use NGK bpr63s plugs gapped at .028. Definitely check plug wires and change if they are bad which you have already covered. Check your timing, change your fuel filter, clean your injectors and even cleaning the throttle body. I hope some of that helps. I will be changing my plugs and fuel filter tonight to see if that helps. Good Luck.

Could be a cylinder miss fire. Check your plugs and wires like the previous poster said.

is the car a 1g or a 2g?

check for leaks on the intake between the turbo and maf.

is it 2k rpm exactly every time no matter what the load?

1g no leaks depends on load

Thats strange. Does it ever not do it?

What is done to the car?, What year is it? Logger? Tuning device?

stock except 16g. 92 gsx. i believe its an maf issue i put another one in and it seems to be running fine other then the maf has no honey combs in it. but my data logger is on the way so i can get my gm maf hooked up.

and the only other culprit i can get from this if the maf doesnt work is a bad ecu

don't forget the wires, check for continuity. but its either weak spark or maf.

fixed ignition timing was horribly off
