Lack of power and Gas Mileage.
Just FYI, I purchase my flexible brake lines from these folks - a bit more expensive, but I buy once and I'm done - https://www.crownperformance.com/
I just seen they only list 2003 on that website
Contact them by phone, as they do not list all of the lines they make in their online catalog. They will make most any braided brake lines for you. My friend did that and they sent him the flexible braided brake lines for his '96 Ram 1500 2WD truck.
I'll keep them in mind
You need a graphing scan tool to somewhat accurately show upstream O2 data since it constantly oscillates high/low voltage at a fast frequency. Your scanner is just taking a snapshot every once in a while. OBDII has limitations especially when viewing multiple PID data the refresh slows down due to limitations of the bus. It's like downloading multiple files on a 56k modem.
Using that scanner to read downstream O2 is fine as it's normally stable voltage output. LTFT doesn't change quickly it's fine for that too.
Reading STFT with that device can lead to misdiagnosis ... it changes value to quickly for that occasional snapshot reading to be of value. Seeing a single snapshot of +20% STFT tells me little other than it could be a lean, could be a cylinder not firing, dumping O2 into the exhaust
An oscilloscope is the best way to show upstream O2 data and STFT . Can probably find a ScannerDanner youtube showing what those 2 look like on a scope.
MAP sensor is easily tested. Should read 29.9 in hg Key On Engine Off. A hand vacuum pump draw down to 20 in hg (typical idle vacuum) and read data from scan tool.
That bad mpg I'd give it a good look over. Compression test. Fuel pressure test + leakdown, injector tester (gadget that pulses injectors for a specific time, so you can compare PSI drop in fuel pressure and see if injectors have relatively same flow rate). Check dist cap and rotor. Read your plugs.
We got speed density (no MAF) so a large leak isn't a as big a deal as it is with a MAF. PCM determines air volume by RPM and MAP.
Saw a really cheap scope with built in display (no laptop needed) $130 on youtube recently so easy to pull up in my history: review

My fluke meter has a bar along with a digital read out. Will do the same thing just not a scope. I'm not knocking scopes, I love them. Problem is a lot of budget scanners with them are slow and there is a delay. This one of many "pico" type scopes out there.
makes a scope with multiple inputs that you can read in real time but need a laptop to display it. I used one of these and like it.
