idles but.......

[nissan4x4]

My pathfinder idles pretty good but you can not get it to go above 2,000 rpm it will start popping and eventually die.but it will idle forever. and when trying to accelerate and the pedal on the floor it only gets to 2,100 max and pops and slowly starts killing itself.oh and by the way it's a vg 30i. any suggestion would be appreciated very much. thanks ty

Sounds like what mine is doing now. I changed my fuel filter 2 weeks ago, and just replaced my cap and rotor this morning. It started running like that after the cap and rotor swap.

i Replaced the cap and rotor too it started with it not even starting the one day it started and ran really rough and died but i finally got it to idle by itself and it has no power i got it up to 2,000 rpm the other day to move it about 50 feet and it didn't even move. it died like it had no power at all like all the power it had was just to keep it running.Do you think the timing is off?

perhaps you have affected the timing while chanigng the cap/rotor?

[nissan4x4]

thats what i think but i want to get every ones opinion because i want to look at it from every angle.

[zonianbrat]

I would assume timing also. Does it blow any smoke? Can you smell a strong gas smell from the exhaust? Have you changed plugs and wires? Have you changed the oil lately and if you have was it milky looking?

Another thing to check would be the ground on the distributor. IF it's not well connected, worn, or corroded, it can cause issues.

That's pretty hard to do with our distributor cap and rotor alone. Both have one way to go on with no rotational play in them.

[nissan4x4]

can you slowly turn the distributor while the engine is running to get the right adjustment.

Most engines are like that, but if the distrbutor mounting clamp is loose, then the whole distributor could rotate throwing the timing out. At least I have seen this happen on other vehicles. I don't know about his vg30, my pathy doesn't even have a distributor.

Everything on mine is either rusted, corroded, or crusted with salt, mud, oil, AT fluid or all of the above. You need a jack-hammer, pressure washer and 50 gallon jug of PB Blaster just to attempt to work on it.

 

I had it out and about today. it chilled out once it warmed up, but still felt kind of off, almost like it was trying to missfire here and there.

same thing happened to mine i got a tune up they changed fuel filter rotor, cap plugs and wires then after that it wouldn't start. finally got it to start i have it in neutral if i ease on the gas itll go just past 2000rpms then sputter like your talking about or if i give it to much itll sputter and die no matter what. i had it checked out the retards said it much be my clutch but that doesnt explain why its doing it in neutral so im assuming something with the timing, fuel system, ignition im not sure maybe even fuel injectors but i dont see why any of those would stop working after those things were changed.

i finally got it to run i here's how you do it: with the engine idling you loosen the bolt holding the distributor to the engine block loosen it just a little, the rotate the distributor till it sounds like it running smoother and not dieing and a then tighten it back up and take a test drive.

You did read my last post (quoted for you) right? Gimme a jackhammer and I might be able to find this bolt you speak of.

[nissan4x4]

mine came out really easy no fighting it at all.

[exploited789]

thanks for the info ill definitely have to try this

[CRASCA]

Try unplugging the throttle position sensor. When mine did that, I unplugged it and it immediately ran fine, telling me the sensor had gone bad.

I replaced it and everything has been fine since.

A new coil fixed my problems.
