Re: instructions for setting the time .1993 toyota pickup...
Please send me your e-mail address; I will send you the complete timing proceedure; the file I have is a .pdf, and FixYa will not let me upload a .pdf to the FixYa site. I suspect that your cam timing is off on the passenger side of the engine. You want the specs for a 93 V6, correct?

Fig. Fig. 1: 3VZ-E Engine. Firing order-1-2-3-4-5-6. Distributor rotation: counterclockwise ,start by finding timing mark on crank shaft and rotate motor to timing indecater on motor ( to check if that is #1 at top dead center remove spark plug, piston should be at top of cylinder, use a soft object to feel piston come up you need 2 people to do this ,1 to turn motor over by hand and 1 to feel for piston rising now open dist. cap and note location of rotor pointing to #1 ignition wire or that will be now #1 and follow firing order ,if you go to auto zone and create an account (its free) you can get info on timing a motor and cylinder position .I REALLY hope this helped you .if it did let me know.thanks .
If I am not mistaken you have to change out the timing belt also when changing it cause it runs off the timing belt. So you will have to pull the front side of the motor down. Big job did one on a accura
you will need a timing light, mark the timing marks on the crank pulley and on the timing belt cover with chaulk or white paint. Connect the timing light. move the distributor or the crank sensor to align the proper marks and retignten. You can tell if you are advancing the timing by the increase in engine speed.
Do not advance the timing to beyond the specs or you will have spark knock and burn a hole in a piston
Get a T belt from toyota. It has 3 white lines on
it and and arrow mark. 2 lines are solid and one is broken. Put the
arrow facing away from the engine. The cam gears have a dot punched
into them near a certain tooth. This is where the solid white lines
will line up with. The crank gear will have a dot also. It will line up
at 90 degrees from the top, towards the front of the car. This is where
the broken line will match up with. With the belt installed with all
lines on their proper dots and arrow away from the engine, you valve
timming is correct. Of course you need to remove and compress the tensioner also. I assume you know this already since you didn't ask.
My first guess would be a dirty carb/fuel injector set. Run some fuel cleaner through the tank and see if it gets better. You might have to do it through a couple of tanksful. How long since you've had a tune-up? It might just be that time.
