Did this video help you?

Rhage73: heck i would say you are saving the customer money, because the labor of fighting those hoses is way more money than just getting a few hoses. =)

Autotechviewpoint: Good options, and we sometimes do things like that. Would that be "ripping of the customer" to do that? That would through off estimates between shops who would quote the job and the more expensive quote would certainly mean they were trying to rip off the customer, right?! I guess good communication is best, but some people still don' get it.

David Adam: I also recommend buying all new hoses and vacuum lines, rather than fighting with the hoses (takes hours and you'll be extremely tired) you can cut them off and replace them, I would also use conventional hose clamps when reassembling everything rather than the nissan factory "quick hose clamps" I also replaced the manifold bolts with regular gr8 bolts rather than the allen head ones which will make it easier to work on in the future

David Adam: I just cleaned my idle air control valve in my 01 nissan frontier 3.3l v6 vg33e, it's also underneath the intake manifold. Nightmare of a job especially jacking with the all the dry rotted hoses that were all stuck on and had to be removed, every one of the hex head bolts (header style bolts) stripped out on the inside. If you're about to pull your manifold on this engine it helps to have a 13mm and 12mm 12point sockets ready, you can hammer them over the entire head of bolts and it'll grab em

Autotechviewpoint: Kind of depends if you have any previous experience and the right, proper tools to do the job. I think I would pass on this job if i didn't do it for a living...

Mooing Captain: I know this might be a ridiculous question to ask but, would you recommend a home mechanic to replace the knock sensor that's underneath the manifold? After watching this video, it's kinda intimidating. Thanks for the video.

Autotechviewpoint: Top rear of the engine, but I believe that means under the intake in the rear. tough to get to then.

jerry brewer: no on the car

jerry brewer: no on the car.

Autotechviewpoint: To buy? No local parts store has it? Dealer?

Jerry Brewer: were can you find a knock valve sencor on a 1996 pathfinder

Autotechviewpoint: I believe that is correct, under the intake manifold, it maybe nearer the back end of the engine.

omar ramirez: Hello friend that I write to thank you for uploading videos and aprobechar important to ask a question: I have a 2003 nissan frontier v6 does not serve the detonation sensor I want to change but I can not locate where I could say is that I have heard that this sensor under the intake manifold but I removed the distributor can not see anything so I ask guidance. now let me thank you for the infformacion you can ofreserme. greetings.

enkrypt3d: Why didn't you spray a ton of seafoam in those nasty looking intake plenums? Hoping seafoam will clean mine out as the intake manifold is full of black gunk....... well w/o having to remove it that is...but it doesn't seem like removing it makes it any easier to clean.

Autotechviewpoint: I do not know exactly how much you did with the number 6 plug, all I can tell you is that the idle air control may be on the bottom drivers side of the upper intake manifold plenum. Vacuum leak somewhere? Sorry cant be more help.

Michael Warnick: I changed out the passenger side valve cover gasket and all but one of the spark plugs on my 1999 pathfinder. (Cant reach the #6 plug on the drivers side with my current tools) Now it is idling high and almost stalls out at 20 mph to 40 mph. I have to take the overdrive off to get it up to speed. What have I done? How can I fix that?

squall9914: its on your brain under the passenger seat. you'll need a flathead screwdriver. Don't put it into diagnostic mode when setting idle speed.

macboss100: hi guy you seem to know this engine well where is the idle adjust screw there is no information on this but text on internet do you have a pic where this is i have a 97 nissan pathfinder and it runs great when idle it coughs and bounces the rprm then at times stalls but when driving works great i change mass air flow so i just figure i could raise the idle a little to stop this .......any help ......the easy way ???????????

arman757: its either a 27mm or 30mm crowfoot you need for the big egr nut. makes it much easier

Autotechviewpoint: A gasket got messed up, a piece of the old gasket is causing a leak, the idle control is not plugged in... some thoughts.
