22 RE idle problem

[mudbuster22RE]

When I start it its fine untill it warms then it starts surging like crazy and the problem does not go away when i push in the clutch or put it in gear. The best part is when I put it in 2wd the idle speed drops like a brick and when i select any other drive option the idles picks back up. Any ideas please? Thanks a lot guys!

I am new here so take that for what it is worth LOL
what have you checked ? not much info ie: how many mile on truck, when did it problem start. any up grades prior to problem.
I would start with these if yiou have not done so already.

1 look for vacuume leaks
2 clean TB/intake
3 check rotor, plugs, wires,
4 check timing after the above

repost and let us know.
and then we can go from there.

is your coolant full,or check to make sure your thermostat is opening .I have recently found out that the coolant temp sensor can cause this problem

About half of the ECU codes stored on the first & second generation EFI Toyotas don't show a constant blinking check engine light therefore you must pull the ECU codes and auto tranny computer codes to see if a fault is registered.
To pull the ECU codes:

All 1980-1995 and including 1995 EFI equipped vehicle allow you to find engine and related faults by pulling the ECU (computer) codes without the need for a handheld OBDII diagnosis scanner,the sites listed below have the fault codes needed to pull the codes and the instructions on how to do it:

Pulling the ECU codes is the first thing I do to diagnosis a problem thereafter I reset the ECU to see if the same problems show up and if so I then take voltage measurements both with the engine running and not and compare with the factory service manual,I also close the ignition switch after a cold engine and also after a warm engine and compare them with the factory service manual.This technique will completely isolate your problem without having to do trial and error and it is the technique I use when repairing tv's,vcr's,home/car audio.

Any Public Library in your area would have the Factory service manual,Haynes,Chiltons,Mitchells,Clymers,Bentley and Toyota repair books.

There is also free AutoZone service manuals at:

2003 Toyota Tacoma Factory Service Manual:

http://www.junglecode.com/toyota/tacoma/2003_fsm/

FSM (factory service manual)can be acquired in several ways:

Toyota Material Distribution Center
750 West Victoria St
Rancho Dominguez/Compton,CA 90220-5538
USA
Ph:1-800-622-2033 (outside CA)(M-F: 7-5 PST)
Ph:1-800-443-7656 (inside CA)
Ph:1-310-818-4630 (in or outside CA)
Speak to Beverly or Deloris
http://techinfo.toyota.com/public/main/mdc.html
http://www.4crawler.com/4x4/FSM.shtml

1)buy a used one off e-bay
2)some Toyota dealerships may give you one or sell it for $10-20 (used) as most Toyota dealerships don't repair many old Toyotas and no longer need the service manual
3)some public libraries sell their old books as they are not in demand any longer
4)some free buy & sell classified papers,websites and bulletin boards may have some used ones for sale
5)some junk yards may have one laying around
6)some Toyota specialty garages may have one laying around and no longer use it as the vehicle may be too old and those mechanics probably have so much experience that they could publish their own factory service manual with corrections and "real world repair tips"
7)if someone has the FSM maybe they could scan all of the pages and post it on a site for all of us to download or view.

Chris do you know anyone who has used factory steel or chrome lug nuts or good aftermarket chrome (qty:24) with black plastic caps in Dartmouth/halifax? for free or low price as I need a set and junk yards just throw them on the ground and don't won't to waste their time keeping them.
