I have a 91 toyota v6 it runs with out the tps right now but I want to put a new one on I no how to set it with a meter but some one told me I will have to take it to a shop for the timing after I install the tps?

 

Get you a factory service manual

 

Here, this will help you with your TPS, a lot of good stuff here.

P.S. If you can dial in your TPS, then you can set the timing also, pretty easy as scope103 explained.

 

You'll do better on your own w/o the shop, setting the timing. You need a timing light, of course, but the cheap $20 one will be perfect. You need to jumper TE1 to E1 on the diagnostic connector (this shuts off the add-ons to base timing; base timing is what you need to set). And the setting (degrees BTDC) are on the sticker under your hood.
