Throttle acts like I'm getting on the gas when I'm not, in pulses.

Happens at low rpm low load, inability to cruise unless at around 3500 rpm

Well since its a z engine in an s14 and it's wired up I figured it might be more of an issue with calibration or wiring.

Also you may want to check the TPS adjustment. Mine was off on my vg30dett

I had a similar problem with my 300na 1990. It was the right hand o2 sensor. It would run terrible with throttle just cracked, but wuld run sweet above 3k, about 67 mph.
