Re: P0304

Well, since replacing EVERY sensor on the engine didn't fix it I figured it was something else. ;) JK. It finally gave me a P0174, System too lean (bank 2,) so I used some TB cleaner to spray around the intake and collector and the engine nearly took off when the stream hit the manifold at number 4....

Re: P0304

This turned out to be an Intake Manifold Gasket. The gasket that I put in was a paper type gasket and it failed right around cylinder 4. I replaced it with an OEM gasket and the life is back into my Pathfinder.

Sounds like the neutral safety switch might be going to me. Or the connector is corroded. The next time it wont start, hold the key in the start position and move the shifter back and forth or push it forward a little or move it to neutral and see it starts. On Chevy's you used to have to hold up on...

The fuel pump didn't fix the problem, but my fuel gauge works now. I'm getting a P0300 now (random misfire) instead of a P0304. I'm going for the position sensors next. I still have to get the fuel tank sling bracket fixed. No one around here want's to attempt to fix it so I guess I buy a welder and...

Man that's a lot of rust. I've been lucky so far. I lived in Colorado for 20 years so there's a lot of snow but they use Magnesium Chloride for snow. It doesn't rust everything out but it'll mess up the shine on your paint if you're the type that never washes your vehicle. I lived a couple of years ...

Finally able to test the fuel pump. The pressure stayed at 51 psi while the engine was running but when the engine started idling rough the pressure would jump around. Since it took forever to get the fuel pump and the fuel gage was messed up I decided to go ahead with the fuel pump replacement. The...

I was hoping that was the case. I don't mind. I don't think they've affected anything other than my curiosity. Well, anxiety maybe. :) I might try brighter, though. Thanks.

Glowing LEDs

So I had a dome light burn out and I decided to go with LED replacements so I could get brighter lights inside. It looks much better than the incandescent bulbs. I replaced all five bulbs. A few days ago I noticed the bulbs glowing when the PF is turned off. I checked them several times and made sur...

Well the engine didn't eat itself. I'm pretty sure it's the fuel pump but I don't have a way to test it yet. The kit I purchased that said it worked on my PF, doesn't, so I'll send it back and get the correct adapter. I tested the compression on all six cylinders and they range from 178 to 182 PSI. ...

That's the plan for Saturday. I checked the wiring to make sure everything was plugged in correctly. I'm going to start with a fuel pressure test. When it first started, I thought it was running out of gas so I'll try that first. The fuel pump is about six years old. Then move on to the compression ...

Changed the spark plug with a new one. Still getting the P0304. I'm not sure where to go from here. The engine was running beautifully. Great power and 3 more MPG. It was idling smoother than it ever has. It's not using any oil. It's got close to 2000 miles since the new heads. I guess I get the FSM...

P0304

Well, here we go again. After the new heads were installed it's been running great until Sunday. I started feeling a miss when idling. Then it started running really rough. P0304 code thrown. So I switched the #2 and #4 coils. Same error so I thought fuel injector. I swapped out the fuel injector wi...

You can purchase an upgrade online. They'll send you the DVD for updated maps. I have an 06 and I purchased a 2015 map DVD. I read it was the last update that will be produced but I don't know if that's true. I think it cost about $40. The DVD goes in the DVD player under the front passenger seat. I...

Interior paint

Hey Everyone, I'm trying to fix up my PF a bit. I plan on driving it until it absolutely will not run anymore. It's an LE with navigation and Bose and the Blue/Graphite interior. I screwed up my bezel that goes around the nav screen that also has all the HVAC controls on it. Nissan no longer sells t...

It's all back together and everything seems fine. I've been driving it for a few days now. It's running smoothly. The knock is gone. No extra noises. It's peppy, but it always has been. That's why I keep it. I think I got lucky.
