Yeah, it's a backfire... right out the intake... although, now at least it's getting worse (it used to be just this little problem that would bug the heck outta me every time it appeared).... Now I'm thinking I need new injector(s)... specifically the #2 injector... When i put the ECU into diagnositc mode 3, when it fires the injectors (yet no fuel passes through, wierd...) I individaully connected each injector, and the #2 injector is REALLY quiet compared to the other ones.... so I'm thinking there's not enough fuel going through the injectors... my fuel pressure is right around 40 PSi (more on how i hooked that up in a new post), higher by a few when i rev the motor, or disconnect the FPR vacuum line... What's strange now is that when i give it gas, it sputters sometimes at higher RPM for a few seconds, then it will take off like mad! ,(as if the ECU is trying to compensate for the one dying injector)... also, unlike the 8v, there is really no way the injector spray on the 16v can get to the other cylinders.... so, the new injectors (24 lb/hr saturation-driver) come in on friday...
