Old toyota trucks & timing

WealdstoneRaider
Over the years I've failed many toyota's in regards to timing being too advanced and when the customer goes to a shop on some instances the mechanic ''can't'' retard the timing to the specified degree example: 22R engine timing for 89 truck timing needs to be at 5 degrees but only retards to 15 degrees and can't go lower etc. What may be the cause of this? A rebuilt engine that timing belt might be off a tooth or? Just curious.
want sm'ting I'll give it to ya

In order for the computer to go into "base timing mode" the computer needs to see the "IDL" contact of the TPS closed. If it doesn't close it will SHOW too far advance. If you grab the throttle and hold it closed you can get it to close the contact some times.

If their mechanic is any good he will know this and adjust the TPS first.
Good judgement comes from experience. And experience? Well that comes from poor judgement.

Why make it simple, when it will work equally as well complicated.
