HI, I have a 93 Nissan Sentra XE , 1.6 L american VIN...I have replaced in the last year the battery, alternator, battery terminals ad wires, full tune up, both front and rear brake syatem, both front tie rods, the exaust from engine to muffler including all new gaskets, hangers, bolts and the gas tank/fuel filter...

My question/problem is...While on the highway after 55 mph if I let of the gass it sputters and acts like it wants to stall...also while idling it acts as if it is about to stall and sometimes does and sometimes it races back up on its own...what can cause this? How do I fx it? It only has 128000 miles, I have put a lot of money in it and is great on gas and never has left me stranded from a breakdown. I want to fix it as I just puy the new wxaust system on..Please help.

Check the airflow meter, throttle positon sensor, EGR valve and the IACV-AAC valve-also inspect the exhaust system for restriction
