hi guys
haven't seen this one really covered, but i just had the NRMA come round to check out my car
recently my 4agte celica has started pinging, until the other day it started to backfire and hesiate at low gear, and eventually all gears.
It is definately timing, but i am unsure of how to set it without a distributor.
anyone can give me a step by step?
it's a series 2 4AGZE. coilpacks, crank angle sensor, AFM
thanks

from memory you can change the base timing by adjusting the crank angle sensor.

would it be the same as a TPS? just unscrew and rotate the gear?

Its just like rotating a dizzy
the CAS is practically the bottom half of a dizzy with a cap on it, just loosen the bolts that hold the CAS in and twist as u would a dizzy

there will be a little box that says diagnostic or something like that, and you need to bridge T1 and E1 (diagram under the cap) with a paper clip, or little bit of wire..which will disable the advance/retard on the timing..thus letting you adjust the base timing..books suggest 10deg..but you can get up to 12-13deg befor you have any dramas..

on my aw11 mr2, its on the back firewall, its about 1.5cm by 2.5 cm rectangle little box that says diagnostic on it. I have no idea where it would be in your car.

i wouldnt go twisting it willy nilly and driving it, i would get a timming light, and actually know what your doing. Failing that, take it to a mechanic that can do it for you.
