[justridecyclez]

hello.i rescently purchased a 1990 toyota v6 extra cab fuel injection.

The truck will not hold a idle.It simply stalls.It starts easy and stalls unless you keep ur foot on the pedle.
I brought it to toyota and said they were geting wacky reading.They checked eveything and said it needs a computer.They ordered a computer put it in and it still wont idle.
The mech says he has no idea and cant do anything else.i have since then took it from the mech and trying to fix the proplem myself.
any help would be great !
thanks

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,Clydes,Mitchells,Bentley and Toyota repair books.

There is also free AutoZone service manuals at:

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

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.

My I4 Camry did that years ago. If it went below like 1,500RPM's it wouls stall. The EGR (I think that is what it was), was replaced, and it worked fine. That was after a lotta hell that they found that to be the problem.
