#2440 of 2501 2000 4Runner Door Rattles by leonoto Mar 10, 2009 (7:52 am)
I have seen a lot of posts about door rattles, but none of them seem to be the kind of rattle I have. If anyone knows what the cause or solution to this problem is, please let me know. On my 95k mile 2000 4Runner, all my doors rattle and squeak against the frame of the truck when hitting minor bumps. Sometimes it sounds like the rubber stripping is squeaking as the door vibrates, but other times, especially in the rear hatch, it sounds like a metal on metal grinding banging noise when hitting bumps. I've adjusted the striker plates on the front two doors to no avail. Since that didn't fix the problem, I didn't try it on the other doors. All the rubber stops are in place (some had to be replaced). The rattles seem to be reduced in really warm weather and magnify in really cold weather. I have been chasing this problem since I bought the truck two years ago. Any advice would be greatly appreciated. As far as I know, the truck hasn't been off road other than mountain forest service roads, and the previous owners definitely didn't rally the truck. I also know that the origin of the rattles isn't inside the door panels since I have dismantled them and ensured tight screws and bolts all around. My hunches: - Doors need to be completely re adjusted (at hinges and striker plates). This is an expensive option since I don't feel comfortable adjusting the hinges myself. - Weather stripping is of poor quality and could be replaced   Otherwise I love my truck, and it is in great shape and well maintained. But the rattles just drive me crazy! Thanks for your help.
#2441 of 2501 What Maintenance Is Needed by rjordan393 Mar 11, 2009 (2:02 pm)
2004 v6 4wd with 20,000 miles. I bought it with 4890 miles on it. Oil and oil filter changes once a year. I am looking at changing the transmission oil and cooling fluids this Spring. About 85% of the mileage is stop and go driving in an urban setting. Right now, I am experiencing low mileage and will test at the next fillup. I was wondering whether if I also should have the mechanic check the fuel injectors? If so, then is on the vehicle cleaning ok or should I go with off the vehicle cleaning. I have only used 95 octane gas. What does the toyota mechanic check when low mileage is the complaint? Should I also consider other maintenance?

Replying to: rjordan393 (Mar 11, 2009 2:02 pm) Your low mpg is bcuz of the urban driving. My 2003 gets as low as 14.5 city. As for maintenance, just go by the owners manual. If you don't have it then it's available online at Toyota's website, although you might have to register as an owner to see it. Fwiw, change the oil more often - at least every 6 months.

Hi, i have a 1997 4runner SR5 great truck wouldn't trade it in for anthing else. My engine light is on and I did a diagnostics and its showing the o2 sensors.

Replying to: hector13 (Mar 15, 2009 6:12 pm) I believe there re two O2 censors - the yare not cheap. I am on my way today to get one replaced. I've been driving with my check engine light on for about 1 year now - I know it's the O2 censor. Not a huge deal, jsut lower gas mileage at this point, but it is due.   I've got 130,000 on my 01 4WD 'Runner w/Sport package and it still runs like it's new aside from the censor.

#2446 of 2501 2002 Highlander CEL, VSC & TRAC issue by woodstoc Mar 27, 2009 (11:44 am)
Hello everyone, New to the forum.   My wife's 02 HL's CEL, VSC & TRAC lights came on after a wash after a car wash sometime ago. After a couple of days, the lights went out so I figured that a connection got wet and caused the lights.   Buy a pressure washer about three weeks ago, and wife decided to wash the HL with it. Lo and behold, here they are again on the dash. After two weeks, I disconnected the battery and restored. Lights went away. After a few times of driving, they are back on and the SUV cannot be inspected.   Any ideas of where a connection might be, that could cause this so I can begin to troubleshoot? (The engine compartment was not opened for the wash)   Thanks for any replies. Replies to this message: tech17 (May 13, 2009 4:22 pm)
#2447 of 2501 Re: 90 4runner timing mark moving [thattrailerguy] by bc4x4runner1 Mar 29, 2009 (6:32 pm)
Replying to: thattrailerguy (Sep 10, 2007 1:23 pm) Hey. I ahve a 90 4 runner V6 and have the same problem as you. Did you ever resolve the issue??? I am thinking something with the Coil maybe??? The coil resistance in my truck is a little high.. 0.7 Ohms and the FSM specs 0.4 - 0.5 Ohms. Maybe a short??? I also get Codes on my CEL. 13 , 42 and 43   13 -- No IGf Signal 42 -- No IDL or NSW or A/C Signal 43 -- No Speed Sensor Signal.   Jumping out the plug for base timing doesn't work. (Same effect as not jumpering). I dont notice very much change in truck RPM when I connect the jumper either...seems a bit strange. I Know the timing is "close" because otherwise the truck would run like a real turd rather then rough, hesitate, poor gas mileage and maaad vibration at about 110km/h Replies to this message: woodstoc (Mar 30, 2009 5:35 am) tech17 (May 13, 2009 4:33 pm)
#2448 of 2501 Re: 90 4runner timing mark moving [bc4x4runner1] by woodstoc Mar 30, 2009 (5:35 am)
Replying to: bc4x4runner1 (Mar 29, 2009 6:32 pm) I had Autozone pull the codes and they point to the bank 1 O2 sensor. Some research shows this to be the one at the back of the engine, prior to the cat. I'm hoping that water got into the elec connector and caused a short or corrosion issue. I plan on checking that this evening. If this doesn't work, I'll replace the sensor next.   Sorry, I don't know enought about these trucks to help with your issue. This is the wifes car and I mostly tinker with my vette. Replies to this message: tech17 (May 13, 2009 4:33 pm)
#2449 of 2501 4runner tire air pressure by jrpoole Apr 08, 2009 (5:34 pm)
I have a 1999 4runner limited, how do I know which tire air pressure to use? The value that the tire says, or the value written inside the driver door area? Sorry if it's a newb question, I wasn't sure as both values are pretty different. (The one on the tire is a lot higher).
