My 2001 Nissan Sentra 1.8L is having idling and running problems. While idling (in gear or in park) the car would occasionally just die all of a sudden but would start right up without trouble. While operating at highway speed, the engine would occasionally lose power for 1-2 secs and come back on. It also hesitates occassionally when throttled. When this happens I notice a clicking coming from the area where the fuel pump relay is. I also notice a buzzard type sound (CEL flutters also) from the passenger side of the car. Ive given this car a complete tune-up, changed out the fuel pump, vacuum purge cannister, fuel pump relay, crank shaft position sensor and MAF sensor. The car can run like new for a couple of days without incident or it could start showing those problems for days on end. This happens in the cold or hot weather and cold or hot starts.
Any suggestions would help as I dont even have a CEL light to troubleshoot.
Thanks in advance for the help.
Mcdevito75 here, I woild bring the car to an auto electrical shop and have them check out the entire electrical system.
The
shifter needs to be inspected. The shifter assembly is got misaligned, it has
to be open and realign.
There
are many other possibilities. But if it was working right up till now and
suddenly this occurred then its shifter
assembly alignment issue.
Also
i suggest you to refer these gear shift issues, which are mostly noticed. These
are direct links with appropriate solutions to
the specific problems of gear ****.

I had a similar issue that kept happening for about a year. As it was still covered, I would just bring it back to the shop and they would always have to call for advice. They would replace some part, and then it would happen again. After Nissan replacing what seemed like almost every part in the car, they switched out some wires under the dash and that finally did the trick. I almost sold the car because of this problem!!! But it's performed flawlessly since the last repair.
Well, I ended up taking it to the dealer to finally solve this problem when my car failed to start one morning. There was a frayed wire (blue/white) leading to the computer (left side engine compartment) which would cause an interruption of power. Tech said he sees about 3 or 4 cases a year regarding my same problem because the wiring harness which runs from the battery, underneath the radiatior and to the computer is too short. During the course of driving the wires are pulled and rubbed against metal parts which cause them to fray or completely disconnect with intermitten connectivity. A good way to tell its a problem with your computer is that you WONT see the CEL on your dash when you encounter no starts. Problem solved.
