Hello,
Well to start out the car is a completely stock 1996 Eclipse RS N/T 420a with a M/T. Only aftermarket thing done to it is a short ram air intake that I installed 3 years ago.
Anyways, so I was driving out of town one weekend when the car completely died on me and wouldn't start back up. I took a scanner to it and stated no signal from cam or crankshaft position sensor so I replaced both sensor with new pigtails and found the source of my problem, the old wires jackets broke and were arcing together.
After that was all fixed, the car started up but now I get the P0300 code but drives, starts and accelerates just fine no issues so I replaced spark plugs, no change, changed spark plug wires, nothing, replaced coil pack, nada, replaced fuel filter, nope, checked fuel pressure, held steady at 50 psi. I pulled the plugs they look fine and don't smell like gas on them and it shows normal wear and checked the gap they are fine, they are copper autolite plugs by the way.
I checked timing belt and it still lines up with proper tension. I've used the OBD scanner to check STFT fuel trims while idling and they are showing normal changes (less that 2% changes) I smell the exhaust and don't smell anything weird like the cat is clogged and I checked vacuum and it stays close to 20hg so I'm stumped.
I can accelerate to 80 mph just fine, its idles in stop and go traffic just fine, and accelerates with no hesitations whatsoever.
The only thing happening is the check engine light is on and when I'm cruising at a steady highway speed sometimes the light will blink then go solid again with no loss of power whatsoever.
This is my daily driver so I'm trying to get this thing running without the light on. Do you guys think it could be a misreading or that something else is going on? any help would be appreciated, been driving like this for 3 weeks now but no other codes besides the P0300 are popping up with no change to driveability

I was lucky enough that my old sensor worked still, but before u pull a me and buy all these new sensors and stuff test the circuit first. all my sensors worked fine and still do it was just those two wires I had to fix by the egr valve
