I Just picked up a GVR4 and it sputters-cuts out at 3-4k RPM 0-5psi will go up to 4K rpm's cold and 3k warm.

I did the buzer thing and I got this

Long short
1 1
2 1
2 5
1 1
2 1
2 5

looks like to me a 21 Engine coolant temperature sensor and 25 Barometric pressure sensor or did I read the info wrong? Im working on trying to data log but my old laptop is having issues.....


so far
I removed the boost controller
put in a new fuel filter
new plugs & wires
put on some new couplers

What do you guys think my next step should be?
