Fuel filter?

[clr1024]

In all the years of owning my car, I've never known but always wondered what that part was. Thanks for the knowledge.:smile:

One person says disconnect the O2's and if it runs the same it's the sensors. Somebody else says vice versa. I have def lost power and it idles rough. Almost like a vibration. I'm changing the fuel filter, plugs, and sensors tomorrow since I already have them. Is it normal to unplug the MAF sensor and the car runs exactly the same? Any more advice would be helpful!

I recommend actually reading the posts when you ask for advice...or dont ask. Nobody said if it runs the same it is the sensors (there is no disagreement). You have had several people recommend pulling the code for your error(s) to actually diagnose the problem before throwing parts at it, but you've only thrown parts at it.

Why ask for more help when you haven't used what help has already been given?

Btw I say codes (plural) because you'll now have the real original code plus the codes you generated by unplugging the O2 sensors. You can clear the ECU to get rid if the false ones. Then drive around until CEL comes on again and you'll have just the real one when you jump the service connector.

Fuel filter is in engine bay right side between the bay fan and firewall, it's wedged in there but accessable. There are two 10mm head bolts holding the bracket in. Sputtering seems to be a problem others are having as well. My car stumbles every time it's started cold and "pops" back through the plenum for a mile or so then problem goes away as it heats up. Trying to fix this issue and failed emissions tried GTP fuel system cleaner. This stuff just made the car run rougher at idle, refilled the tank so we'll see what happens next. Sigh, another issue to fix!

My NSX is sputtering under anything but WOT, so I'm thinking it may be the fuel filter. I just got the car three days ago and I can't find out where the damn thing is. I also ran lucas fuel treatment which isn't working. Please help!!

Rear coil pack was arcing badly. Fix one problem, have another. Timing belt seems to be noisy now. One day, she will be fixed and ready for some boost.

Now you're messing with fire dude. If you're hearing the TB do not drive the car. This is an interference engine and dropping a TB can really screw these engines up bad (bent valves, etc.). Take care!

That's exactly what I did. Put it right back in the garage. Tough job to replace it I take it? Thanks for all of your guys help.

Are you sure you are hearing noise from the timing belt? Could it be that you need a valve clearance adjustment?

 

[NSX_Acura_91]

It could be but it sounds like a rotating part. The noise is in the front of the engine. The valves make some noise of there own. I don't want to drive it and find out if it is the belt when it decides to go. Maybe it needs adjusted? It has 68,600 miles on it...

It's not the miles so much as the age on the TB. You could be hearing the water pump, idler pulley or tensioner pulley. I've replaced 4 or 5 TB's on other cars and the NSX was by far the most difficult. There are some good write-ups on this site though. Good Luck.
