Greetings to all!!!!
I have owned my 2nd 2001 Land Cruiser for approx. 3 years (the first one was totalled in an accident at 216 K miles). Last summer it began to develop a low speed miss/stalling problems especially when the temperature outside got warmer/hot. The problem was there all winter (low speed miss only) and now has come back worse (low speed miss/stalling at intersections). The check engine (and VSC Trac light) light comes on and I read the code with my reader and it says low speed idle circuit problem (I have an Auto Enginuity laptop reader with the specific Toyota downloads).
I have a steep hill by my house and when I go from a stop to moving up the hill under load it misses and the check engine light flashes.
Last night I brought home a new 18' covered trailer and had to back it up my driveway in the dark (it took several tries in the dark). By the time I finished backing it up the driveway my battery light came on and the lights were dimmer than normal.
I've had the battery and alternator checked out at different places and they both check out OK. One of the places that checked out the alternator told me that the serpentine belt tensioner was too loose and thus the belt was slipping (I have noticed from time to time that the belt does make a small, not very loud noise when rotating around the pulleys).
When I drive the vehicle at higher speeds/RPM's it runs lke a champ (even with 186 K miles on it).
Has anyone else experiened this problem before?
Any advice to help me diagnose this problem is greatly appreciated.
How difficult is the belt tensioner to replace?
