Nissan - Nx :: Starts / Runs Fine For A Few Seconds Then Surging / Pulsing Idle?
Aug 25, 2016
Having some problems with my 92 Nissan NX2000. i just finished changing the clutch on the car now its acting horrible.
When i start the car, it will run decent for like 2 or 3 seconds then the idle drops down till it almost dies, catches itself, idle goes up to about 500 were it will pulse around for a few seconds until it dies. If i rev it it will stay running, kept it running for about 2 mins. but as soon as i let off it will pulse at 500 until it dies
After i changed the clutch it started up fine, it ran great for about 20 seconds before it just died. when i started it after is when the problem arose.
I took a video of the car running, which can be seen here. [URL] .... (It has never caught itself like that before and jumped up to 1000 rpms before. It normally will die at that point)
The video is really quiet, not sure what happened there. if need be i can get a video of the engine bay so its louder, was mainly focused on the RPMs.
Here's a few things i tried: Checked fuses, Changed spark plug wires, made sure they were all seated good, MAF wires were rubbed a bit so i cut the MAF pigtail off one of my other sentras and soldered it on,Changed to a good battery, Changed fuel filter, Added more gas (in cause gauge is broken), Made sure all connectors are plugged in, Checked around for vacuum leaks, found that one of the large hoses coming off the intake going to the engine had separated so i plugged them back in and nothing.

I've been having some issues with my mk4 R32. Right now i'm leaning toward changing the fuel pump and filter but i want to be sure before i do.....
Problem: I've been daily driving my r32 to work for the past couple weeks and about once a week it will start, idle for a couple seconds and then just bog out and die. no codes, just idle, then chugging and dying. it will fire with some starter fluid and will sometimes hold a very sickly idle but most the time will just run the starter fluid out. the weird thing is is that it's intermittent and will happen randomly and if i leave it overnight or sitting for a couple hours it will fire up like nothing was wrong. i just wanted some input on what it might be before i replace the pump. i have already done the relay so its not that.... the only code that it has ever thrown while i have owned it was for the intake changeover valve (N156) which i cleared and it hasnt yet to come up again.....

Starts fine. Runs fine till warmed up. Then dies at idle and runs rough on gear till 1000 rpm. Has only coded iac when unplugged. But would idle with it unplugged. I replaced it. Also got crank can code once while checking it ...

A few days ago, I went to start the car, and it will start, and idle fine for a few seconds, and then begin to run crappy, idle down, and die. I tried starting it, and giving it some accelerator pedal, and it dies. I changed the timing belt, idler pulley, and tensioner this summer, so I'm ruling out a bad timing belt. There is no check engine light, and I replaced the plug wires because when I removed the cover, I noticed one of them was worn in a spot, and the wire shielding inside the rubber insulation was visible.

I have an issue with my 7.3.... the truck will not start if it sits overnight without being plugged in, even in 65 degree weather. It starts and runs with a rough idle for about 10 seconds after its been plugged in for an hour, after the rough idle is gone it runs great .. it will Stat back up as long as the truck is warm (70+).... I've replaced the batteries, glow plugs, starter (it was going bad) and fuel filter. .. also replaced the gpr today. ....

I start the car - a 2001 Ford Focus 4 cyl DOHC. It runs fine for 30 seconds then stops, as if it is no longer getting fuel. I can't start it again for a couple days then the same thing happens over again. FWIW, I parked the car for 8 months before this happened and only started it once in that time. But it ran fine then and before I parked it. What can this be?

The car will start up and drive just fine but as soon as you turn it off, it will not turn back on. If you wait three to four hours it will restart with no problem. This repeats its self daily. When you turn the key the dash lights come on but will not crank at all. I am skeptical that it might be the alarm system;however, there is no key fab and no code for the check engine. It has 170K miles. Laughing, my sweet husband dictated this...my first attempt to describe the problem was long and rambling!

I have an 04 w12 with 80k miles on it. It will start fine but will not run for more than 10 seconds. As it idles down from startup it settles to about 700 RPM's where it normally does then dies. If u drive it it will start and go into gear fine as u go to pull away it loses all power and dies. I have checked the minor things i know like air filters, oil, tranny juice all appears normal. New batteries less than 3 months ago also.

I have Warn hubs that I have to lock in. All works good. A/C goes to defrost at first when cranking but then runs fine after a couple seconds. So, I was thinking that maybe my pump is running all the time. Who knows. I'm sure all my vacuum lines are dry rotted. What exactly is the need for it exactly and what's the best way to cap? Hoping to do it at the unit itself if possible.

I am working on my father's boss' 2004 Phaeton V8. The car usually sits on the weekends. What it is doing is, it will start and run smooth, but after 15 seconds, on the dot, it stalls and dies. It sounds like it is starving for fuel.
What I have done so far:
LH intake actuator arm found broken, replaced both with "Gruvenparts"
Checked all fuses and relays
LH fuel pump reads 14 volts until the relay kicks it off
Tested fuel pressure-good
Batteries fully charged
LH fuel pump reads 0.7 ohms w/key off
RH fuel pump reads 6.0 M-ohms when first connected and gradually climbs to 31.5 M-ohms
(I assumed this meant RH pump was bad and so I pulled it out and bench-tested. Ran perfect and tested at 0.7 ohms out of the car)
Re-assembled everything to pull the car out of the shop, and wouldn't you know it started and ran like normal.
Road-tested for 2 hours the next day without any problems.
So, I call the customer to pick it up and he says he will be there 2 days later.

2010 Cobalt, LS 2.2 Ecotec, with 13.7k miles. Oil level normal and battery voltage = 12.5V.
I've bought the car new in Feb. 2001. Car started and ran normally for the work commute on Friday, 9/2. Today the Cobalt starts normally, runs for 2-3 seconds, and then stalls. The accelerator has no effect. It's already been towed to the dealer..

One of my friends recently asked me to change the timing belt on his 2004 Passat 1.8T. I put on everything as instructed by the manual that the parts department gave me. However, when I start the engine, it runs perfectly for about three seconds, then starts rattling, and stalls out. I took the belt off and put it back on three times and yet, it still continues. This rattling seems to be coming somewhere from within the exhaust system near the engine and sounds like a back-fire. The check engine light also appears when this begins happening. I replaced everything, water pump, pully, tensioner, and etc. Note, I am a professional mechanic and have worked on several Volkswagen cars, including my own, but I never encountered a problem like this one.

Car starts runs rough for a few seconds then shuts off (spark plugs and 2 coils were replaced a few months ago). Coolant reservoir level was way low so I filled to the full line, kept the cap off to cycle. During the time the car starts, the coolant from the reservoir violently "boils" over (out of the reservoir). Huge amount of white smoke from the rear exhaust and a burning smell.
Used Techstream and got the following codes:
Engine and ECT: P0117, P0302, P3190, P3191
Hybrid Control: P0A0F
Intermittently get misfile codes but this time around they did not return.

I've got 200k on my Lariat. Engine was replaced 60k ago. It's in outstanding shape and is driven a lot. Suddenly this morning I start as usual and it runs about 5 seconds then stalls out. Every start, same thing. So it seems I am getting fuel pressure to start but it doesn't last.
I did replace the Fuel Pump Module within the past two years, due to corrosion of the FPM housing. At that time the truck would no start at all. Could it have gone bad already? I'm thinking this must be an electronics failure. It was perfect all day yesterday. 2004 Lariat 5.4...

My 2001 Prius (230,000 miles) is unusable. I can clear the codes. The engine will start up fine. After a few seconds it starts bucking and jerking as if the engine is trying to engage something that won't turn and finally stalls. It is similar to a manual transmission car's action if you fail to push the clutch in when you stop the car. What the engine is trying to engage? I don't have any scanner to read the codes.

I have a 2002 Nissan Quest. It starts fine, idles great. But, when I try to accelerate, the car bogs, hesitates, misfires and I get p0300 random misfire, p0325 knock sensor. I get no dtc when it is just idling. The fuel pressure is fine, regulator works good, the cam sensor is clean, the coil tests good, the compression is good, as are the wires, cap and rotor.

1994 Maxima SE 5 speed manual with 178k runs great when engine is cold, then a cylinder starts missing. Symptom is worse in low gears. Then, miles and miles without a miss. Replaced rear ignition coil and it seemed to fix the problem... for about 20 miles, then it started missing again. And stops missing… for miles.

Trucks been running perfect for 11,000 miles atleast. its last issue was a bad turbo but that was my fault. No issues whatsoever since. 10 miles down the road from work last night truck had a slight miss in between 55-60 for four or five seconds, I put the pedal down and brought it up to 75 or so just to see if it was my imagination and it felt fine so i wrote it off. It ran fine to the house we're working on i wanted to check on before I got home.
Parked it, it idled down to 650 before it came back up to 750 and it never does that and sounded different then it usually does. so i felt something was definitely up. i shut it off, was at the house about a half hour before i decided to head home, started and ran fine, three miles down the road the slight miss came back, it seemed to go away if i got on it pretty good and when i let off but just cruising with slight throttle it had the slight miss.
Got to my road where i had to slow down and turn and it idled down and died. I coasted over, unplugged the icp sensor and it cranked for 10 seconds or so and lazily came back to life. I got it home running decent and parked it. Scanned it with my old super chips tuner and it came up with a p0340 camshaft position code.
Matched my symptoms i felt so this morning i decided id go back to work and grab my spare out of my wrecked truck. truck started and idled perfect. made it to the end of my driveway before the miss came back and then it just died. took the car to work, grabbed my spare camshaft sensor and my maximus scanner, came home scanned it, no returning p0340 cam code but i swapped the camshaft sensor anyway and watched icp and ipr data, the ipr voltage is where it should be and rises while cranking while cranking.
ICP is climbing to almost 3,200 psi and it will begin to run when it peaks out. she'll fire for 45 seconds after 25 seconds of cranking or so and then it'll just die. if it sits for a few minutes it takes a few seconds of cranking before ICP will come off of 0. I've come to the conclusion that it is making high pressure oil it is just dumping it as fast as it can make it. I changed the ipr out because that can do it, it didn't change anything so I'm on to believing an injector is dumping it as fast as possible.
Is it possible for something to come undone inside the injector to make it dump high pressure oil or will a bad o ring cause this? i'm leaning towards a failing injector as when it does fire and run its definitely misfiring and i just put new o rings on them when i swapped them over from my wrecked truck but that was like 45,000 miles ago as well..

I have a '92 Ranger with a 2.3 liter engine. She starts and runs a couple of seconds and shuts down. I'm thinking maybe a fuel pump is not putting out thepressure needed. Gotta go to work tomorrow and gotta get the truck running today.

My '03 7.3 is "surging" on idle. When warmed up, and idling, the RPMs will drop by 300 or 400 for a few seconds and then will correct and shoot back up. It cycles like this (every 5 seconds-ish) continually . I just put in a new IDM and checked the UVCH - is there a separate idle control mechanism that I need to have a look at? (2003, 7.3, 214K, stock).

I have a 2000 volvo S40 19T, it starts up, and will run just fine if you give it any amount of gas, but it just wont idle. I unplugged the MAF sensor and it ran the same. I then took the IAC valve off and put a towel over the port (To let some gas in but not completely shut it off) It runs GREAT like that! I kept the IAC plugged in and the towel over the port, started her up and put a lot of pressure on the towel to cut of all air, the car idle went really really low and then it shut off. Now since the car knows it is stalling, and it needs more air I should be able to see the IAC opening and closing (Remember it is plugged in, but in my hand), it didn't move at all!
I have run the car with my towel over the IAC ports and chased all around the intake manifold and other intake duct work with carb cleaner to try and fine vacuum leaks to no avail. I even did the towel trick with a multimeter hooked up to the wires that plug into the IAC valve, it is getting a small amount of voltage, say 2 to 3 volts, but the new valve still won't open, and I have yet to confirm that the current changes with idle fluctuations when I press on the towel.
