What do you mean by sputtering? My sr20 was doing something similar. it would ide fine but when i went to accelerate it would sputter and cut in and out and have a shit fit. turned out to be rust in the tank. filters were shit plugged too. check that. make sure it has good fuel pressure too. about 40 psi.

Exactly. thats what its doing. I thought it was either injectors.. well something to do with the fuel system or that it was a boost leak... but Im not sure on how to check that. im taking the injectors out tonight and Im going to soak them in "sea foam" and put a bottle in the tank see if that cleans up the problem. Ill also take a look at my fuel filter. thanks

i had a problem like that and it turned out to be a loose coupler.

Coupler?? where is it located?

Your coupler, you know on your intercooler pipe and intercooler. Check to see if there loose or as a slice in them.

Banegraphix · 02-14-2009, 03:13 PM

check to see if your air intake coupler is loose could be that your MAF isn't reading flow

InKfIx2008 · 02-14-2009, 08:33 PM

so i have an update. I checked my sparks plugs while it was running, and I unplugged every one. 3 were good when I pulled off the plug the engine would run like shit. the last one I took off the engine didnt change at all. so I went to go buy new spark plugs and I just put them in... nothing changed,still runs like shit. So does this mean that its the PLUG? WIRES? what is it?? and can anybody in San diego help???

Couped_up'd · 02-14-2009, 08:34 PM

Mine did the same thing, it was the coil packs.
