ok, i have been trying to fix my car for about 2 weeks. when i try changing my timing.. unplugging the tps yada yada.. i know the routine.. it makes my timing change so say i set it to 20 degrees.. i turn the car off reconect. start car and check timing it goes to 0 degrees.

tps reads .45.
cleaned out the iacv..
pulled codes got crank position sensor.. replaced my distributor since thats where its located on ka24de motors.
and my timing is still all whack..

maybe bad wiring in the cps?
bad iacv?

any help would be appreciated... i dont want ppl telling me to search first cuz trust me i have been non stop researching about it.

Update: pulled codes got air flow meter circuit.. Wiped the code didn't come back.. Now after driving the Ecu reads 55 no malfunction.. But still not operating how it should
