My car has been making popping sounds out of the exhaust recently. I'm not sure what the deal is, it takes about 20seconds to crank over of just holding the key. Then when it starts it has a rough stallish idle and if you rev the engine BANG upon RPMs decending.

I'm thinking it may be one or two vacuum hoses but I'm not sure of their names, I replaced one and it was the one behind my intake manifold that is about 2 inches long and had an "L" shape. When this one was torn the car just stalled if you didn't keep the idle up, after I replaced it it was good. I'm thinking i need to order the proper hose instead of using a custom made custom played hose from autozone. Any clue as far as names? pics to come if I get off my booty or enough requests...

 

to me it sound like more of your timing is off but i could be wrong as far as vacuum line leeks could be but i would look at the obvious first like the spark plugs, wires, distributor, rotor you know the basics

 

>_< maybe the timing is off... where is the screw for that thing? I had adjusted the IACV several times... thats not it, is it?

 

Are you sure you're hitting on all 6 cylinders? I had a bad connection/plug wire and wasn't hitting on 1 and it would make a popping sound when rev'ed.
Check your plugs/plug wires/distributor cap, etc. then get back to us.

 

is there an easy way to test this?

 

if you think your car is "missing" in a cylender your best bet is to start the car, open the hood and start pullling the plugs for each cylender 1 at a time then plug it back in, if the cylender is working the car should lose power and become weaker, if you cylender is not working the car will stay the same when unplugged.

 

actually just got done doing that. All my spark plugs were rusted to hell... I replaced them all. it looks like cylinder 2 and 4 are missing. I swapped out the working power pack on cylinder 6 in the cylinders that seemed to not work. no difference. I just put in 6 new fuel injectors.... how do i test power packs how do i test a distributer cap on the ve30de (my father says my car doesn't have it because it has power packs, im confused now)

 

i think i figured out my booboo.... i used a regular hose for a blow-by replacement hose. this sucks I have to order the ****er from nissan

 

definitely the problem... I can't get one today but after inspecting the inside of my replacement hose... it didnt look too happy
