I haven gotten to the compression test yet. I had several other things to do that had time limits.

I think my air intake temperature error P0113 code was due to me not getting the wiring connector pushed in all the way or starting the engine with the wire off. I cleared the code several days ago and it hasn't reset.

My air bag light has been on.

I did order a MaxiScan 903 Bluetooth OBD2 OBDII code reader. I think I will have it in 2 weeks. I bought the low price reader with the idea of buying something that might be able to much more later after I learn a few more things about OBD-2 and all of the optional modules on recent cars. I am investigating what type of scan tools can be had for under $600 to $800.

Things are more complicated since I worked for a car dealership back in 1986. I will admit to wanting tools and being able to use them properly even if it isn't all that practical or cost effective. OTH, if I pay someone to code parts so the car's computer to recognize the new part after a few times, it might pay for the advanced scanner cost.

I reconnected my Innova 3120 today and found the freeze frame data for a P0340 code that showed up again yesterday that didn't reset for 2 weeks.

freeze frame data Innova 3120 closed loop; load 26.6; coolant 183f; short term fuel trim 0%; long term fuel trim 5.4%; intake manifold 8.5 HG; timing 1*; intake air temperature 89f; throttle 13.3; engine RPM 866; MPH 33.

I might have been in neutral or had the clutch pedal to the floor getting ready to change gears or approaching a stop sign when the code was set. The strange thing is the car is almost back to running normal with only an occasional buck.

From what I read the difference in fuel trims might be an issue OR is an issue in 60% of driveability issues.. This is my first experience with fuel trims. I have years and years of experience with carburetors, rich-lean conditions, partially blocking the air intake to richen the mixture and/or adding some form of extra fuel to test for rich or lean conditions. I watched several "fuel trim education videos" but I do not claim I know what I am doing. Right now, learning a few basics is where I am at. I didn't have anything to see if the STFT changed and the videos I watched indicated a problem if a fuel trim was over 10

Over the winter my 10 yr old battery died so I charged it without disconnection the + or - cables. I also might have used jumper wires to start it. One friend said if he uses his car to jump start another car while his donor car is running it messes up his onboard computer/s.
