Haven't been very active on here lately, but I recently brought home a 1998 tracker, 1.6, 3spd auto. It's quite a find considering it has close to zero rust, so I'm pretty excited. It ran great when I first test drove it extensively, but shortly after getting it home it started to act up. It has had a CEL on since purchase but now it's running very poorly. I checked obviously things like ignition wires for looseness, fresh gas, air filter.
I cleared the codes last Friday (when it started acting weird), and a got a p0135 in about 5 minutes, and p0740 (TTC issue, this will come after the o2 sensor) after about 2 days. It often dies when you let off the throttle after giving it light constant throttle in D or R, and wants to stall when going from D to P or N. Since then it will even stall after idling in P or N for only a few minutes.
I will also note that this poor running only happens below around 1500rpm. I have driven about 200 miles since last Friday and it cruises at 60mph like a champ (except for no TTC lockup, but we won't worry about that today). WOT and even half throttle power are both perfect and impressive considering it's a 1.6
Anyway, to get the point. I want to get rid of at least the p0135 code before I go throwing parts around. I downloaded the manual for 96 16v which is the same as mine, but I am having a hard time finding the procedure and voltage/resistance when testing the wiring going to the o2 sensor and also which wires to test (colours would be great). I want to make sure the wiring is all good before I buy and replace the sensor.
In addition to this it was suggested to me to replaces the plugs, wires and rotor cap/button as well as the PCV valve. I'm also considering doing the timing belt since I'm not sure when it was last done.
I've included a couple videos of the issue I'm having for some context.
Here it is on Friday.

Here it is on tuesday. And it's gotten worse since then, and I've stopped driving it. Exhaust
