But for the tensioner actuator replacement not only it’s a 1,000$ part, it also involves removing the camshaft. and I’ve heard horror stories from other forum members on getting it back together If any of you have access to a video or guide on that job It would be super helpful. But as of right now I’ve concluded it’s not a connection issue and there is just a sticking issue where it takes long to change timing and it takes long to switch back I’ll report back tonight on how testing the solenoid goes.

Once you have the cover off it`s recommended to pull the camshafts anyway, so you can replace the two small chain pads on the actuator. The actuator comes off together with the small chain and the two camshafts as a unit. It`s not difficult to do if you have the correct tools.

My biggest fear is not taking the car apart, There is Plenty of information on getting it apart... but I have found absolutely 0 information or guides on actually replacing the actuator and getting those camshafts back on... Once I take the tension off the chain and take the cams off all the valves return to their resting position... So upon reinstalling the cam I have to get it on JUST right and idk how...

I went back and reread your first post.
You stated that your only getting 11 mpg.
Is that correct?
I have a 2000S so it's a 3.2 with a six speed.
I get 23-28 mpg. 23 when I'm playing and 25-28 when I'm driving in my age bracket.
Did you see anything unusual or way out of line when you scanned your live data?

I know you working on the cam timing actuator issue.
But I was curious 11mpg just ain't right

yep. although after cleaning the maf and new spark plugs that went up to 15-17... perhaps just a matter of me needing to fix the car and drive it more...
