x-90 P0335 code

does the timing freeze work , if yes, then all is good, with loose belts and keyways wrecked.
ever seen the 3D map of spark timing?
it is complex but in park or in neutral the advance is not only aggressive upto 40 degrees advance (see that on your scan tool) and bouncing like crazy at idle is normal.
this you will learn even at idle this (magic) saves lots of fuel for sure for the life of the car,
here is a map.. photo, 3d spark map.
the 3d axis's are , RPM, LOAD and advance.
first off suzuki never published such a map (igntion advance 3D) so we can do as look at all cars that have a 3D map.
The ECU computes load, obd2 even reports load. and is based off the MAF sensor,(95HP is max air flow, like on a hill)
The next rule is the ECU does not ever (this car) know true static timing, so the owner job is to do that and the ECu assumes its at 5DegBTDC or as the hood sticker states.
so OBD2 reports (total advance = static adv + computed 3D advance (algebra simple)


but i can drive and plot advance and load and RPM,. sure can but not parked. (its too crazy when car not moving)

Ok so now that you have pretty much all the info in pictures i wanted to let you know something i noticed while timing with the gun. After timing to 5 degrees, i removed the jumper to watch the timing advance as the throttle was increased. What i did notice was every time i would gas the throttle the timing would slightly retard, then advance. Like it would go back a little then move forward. I thought this kind of odd, like how can the crank timing retard slightly before advancing instead of just steadily advancing. Not sure if this is the misfire happening as im gassing the throttle but i thought i would mention it. Ill try and get some photos of it happening or video so you can see what i mean. Other than that im clueless. I need to invest in an oscilloscope but want the 2430 like you have. ( a cheaper analog scope is far better the 2430 most are dead now)
