Replying to: zipper1google (Jan 14, 2008 4:59 pm) This SUV is the worst quality I have owned, it drives like an old pick up truck instead of a semi luxury SUV. Lots of gadgets, that do not work. Dealer not interested, says all problems, normal. I can't decide if that’s Nissan's, answer or the lazy dealer. Coral Springs Nissan FL. Reg. Frank R. Ps. Lease has 26 months to go, wish I could get rid of it next week. |

same or other car makers have source to put in more or less good, but all is depends on suppliers. maybe its just suppliers they use or nothing of that list,  just some manufacturers are switching between suppliers for  some of that new supply may go wrong, and manufacturers don't pay responsibility to cover this its suppliers that warrantied such products which they build. all may seems not that wrong

| your gas mpg might be effected if your pathfinder has a carbon canister that works with fuel system to take the fuel vapors from the gas tank to the intake.... the problem is that the carbon canister that controls that system has an open air breather line that attaches to the inside of the xterra frame... if the pathfinder is build similar, then it has a carbon canister system also...........this open air line can be polluted by dirt and dust.... specially if you had to change your purge valve on the carbon canister.........i just replaced my 2nd valve ........1st one at 44k second one at 100,000 last week... when i removed the valve, i found dirt and dust all over it............ while the 2 other fittings for the other hoses where not visibly polluted with dust or dirt, i took out a compressor line to the center hose fitting and blew a ton of dirt and dust out of the purge valve opening....... so my vapor line has been sending fuel vapors and dust into the intake system........ hummmmmmmmmmmmmmmm something to have checked......... to those who work on their own cars......the purge valve has 2 plastic locking things..... if you try to lift out the purge valve without having the 2 plastic things on the right are, you will rubb plastic of the locking mechanism and will have to use gasket seal to place on the opening of valve as you push it into place and lock it in to position............ also, some of you might want to check your mass air sensor wich i also found with dust on it...... you can clean it by removing and using gloves and special cleaner for the mass sensor cleaner....... good luck... i hope to see some feed back on this important subject.... | |
| after 3 weeks of going crazy over my 10 to 11 mpg i found the mechanic that found the solution. when ever you disconect your battery, your ecu is re-set to re-learning air/fuel procedure wich begins when you start the truck. idle truck to warm, then keep rpm's 1000 to 1500 . take truck to open highway keeping rpm's low and get truck to 60 mph . stay at 60 mph for 15 minutes. my engine performance was at 86% prior to mechanics instructions and re-setting ecu. | |
| Just bought a used 05 LE w/ 40k miles. I'm in SE PA. I can't get anything above 16 mpg mixed. I drive very cautiously, always keeping the rpms below 2500 - most of the time under 2000. Plus I've checked everything I know of and can't get it any better. Is this normal??? | |

Replying to: ckone0814 (Jan 31, 2009 7:17 am) Live South Fl, mixed journeys 5 miles (local roads are 45 mph) to 3 times per week 25 miles each way hwy. On a good day 15.5 mpg. If local only drive, goes down to 13/14. Worst truck I ever had for mpg. My Ford Explorer V8, did better mpg, NYC bumper to bumper, got 12.5 mpg. Reg. Frank R. Ps. this mpg is on screen or tank to tank measure. |

Replying to: waikylam (Feb 03, 2009 4:16 pm) So anyway, it's been in the 50's here the last few days and my 05 Pathy has definitely shown increased mpgs with the warmer temps. I'd guess 1.5 - 2 mpg. so i'd say this adds some support to my "cold oil/oil cooler" theory? |

the best way to find out if your engine is performing correctly is doing a 0 to 60 mph and seing how many seconds it took..... on my v6 2005 xterra, i got 9.9 seconds...........something was really wrong.....specially since i have the 14hp K&N intake kit..... i began to be scared thinking maybe a ring was bad on a cylinder... wrong.... i dont like that when i turn off the truck and sit in it.. sometimes i will see guage needles drop down and go back to normal...... the question is if its re-setting something with the ECU../////////////////// who knows... so if you have disconected the battery for cleaning the posts or something else.... your ecu is under re-learing mode and if you drive as usual the air/fuel mixture will be set wrong.... thus causing a horrible 0 to 60 mph test... disconect your battery for 30 minutes.... then re-conect.. now the ECU is officially under re-learing air/fuel mixture...... start the truck and allow fluids to warm up.... then drive with rpm's under 2,000 (i stayed from 1,400 to 1,600) then head to open highway and get truck up to 60 mph for 15 to 20 minutes..... on some tech sites i have read that 50 miles of driving is best for re-learning procedure. |
