Once you get done performing the maintenance stiff on it your CEL might turn it self off

Speaking of filters, check your cabin air filters. Those things never get changed. When I looked at mine they were filthy! Also, I've heard if you fix the cause of the CEL, it may not always turn off right away. If you can, I'd try clearing the codes now or after you do the plugs and wires and see if the light comes back. Just a thought.

Do you think just taking it in for a diagnostic is a quicker way? Just to pin point my exact issues.
Where is the cabin one?

Might be But I'm not sure. I'd still check the plugs and all that since a tune up "was done" but doesn't seem like it. The cabin filters are on pass side under glove box. Remove the cover below dash(like 3-4 7mm screws iirc) then there's a plastic piece holding the filters in place.

I can record a video. Web it stats up it acts sort of seized or like a dirty plug or injector. But give it some gas and it is just fine then idles perfect.

Ok so today I have finally narrowed down to a few issues. Luckily that ABS is coming up as a resistor and relay issue. Was told it would be about 29.00 for a replacement.
I pulled these three codes. P0302, P0174, P0171 also. What I have gathered and am thinking is that this is the most likely issues. I need to replace my spark plugs, wire, and distributor. I also need to get the fuel filter replaced most likely.
It says that also cylinder misfire detected number 2 explanation. the PCM monitors that crankshaft speed and has a misfire condition: Probably cause is detected as ignition system fault spark plug, ignition wires, or coil. It also says I could have a vacuum leak, or an injector at fault.
So last night i put two large bottles of Berryman injector B-12 into the tank with my gas. I will see how this does to help clean the injectors. If that does nothing this tank on payday I am going to do a full tune up. As well as get a flowmaster 10 series onto it.

Here is the culprit. It was a stupid wire that is completely cut at the base of the plug. I went to auto zone and the guy just gave me a single wire for free.
So obviously a good reason why running to lean. I got a replacement wire and will be doing a full wire upgrade soon.

I also last night tossed these in with a new full tank of gas.
says one bottle for every up to 26 gallons so I figure two bottles will do her some good!

I gotta take a little credit because when I looked at it seemed in order. It idled fine accelerated fine from what I thought but damn it makes a difference. I tossed that wire in at the autozone drove her home and it feels much better even.
