Hi My name is TJ I have done a sr swap in a s13 already now I am doing another one and got a little big problem. It starts up fine idles on its own for a couple seconds and tries to die I can keep it runing and overall sound is good I get in and take it down the road and try to accellerate and it boosts to about 5lbs and stumbles and bounces like a boost dump.Was woundering what sort of possibilities can it be I have swapped out with my other car the following with no help the ecu, mafs, igniter, and plugs. have did some welding on intercooler piping could it have enuff small leacks to act like this? Well anything could help right now I am frustrated. any help welcome thanks

You said you swapper parts with your other car?? is that car a sr20 240 too? It could be some vacuum leak somewhere or boost leak. Maybe you have a bad maf or the wrong on.

yes it is a sr20 car too I have been thinking it is a boost leak too. next step is to swap the piping out to see if that is the problem

You could just pressurize the pipes, and listen for leaks.
