Default hesitation at 4000-5000
I have an 88 gtu with stage 2 porting. I have this issue where at 4000 rpms the engine hesitates for a moment, and then again at about 4800 rpms. Any suggestions? The only thing I can even figure is the secondary air intake port actuators are malfunctioning-but then wouldn't the hesitation only happen once?
