1997 SC2
Default P0300

That's what I'm getting at redline in my 97 SC2 with a computer from a donor car with power windows, power locks, abs, and traction control. I'm going to try to get a computer from a car exactly like mine except manual: no PL, PW, ABS, or TCS. The Service light is always on, and the SES light flashes at redline. Thanks to my handy pocket scanner, I can check the codes on the fly. As soon as I shift... and a few moments later, it goes away.

Some other important info:

I have *GASP* Bosch Platinum +4's with Bosch wires. AFAIK, the *******s are going to be gone ASAP. However, I have fear that the computer won't compensate for the lack of resistor plugs or wires. Is that the reason it's misfiring? I don't wanna blow my motor...

Also, for those who noticed the loose bumper issue, IT'S BEEN FIXED! My dad and I are currently working on fixing the thing that keeps the fender in place and absorbs low speed collisions. Unfortunately, removing the dent won't be too easy. If the bumper and fender will match up, however, that'll be enough for me. The dent will be a reminder of the sacrifice I took (or, rather, Tori took) when I bumped my friend's fat ass of a car out of the mud. (Inside joke )

Also, I'm getting bad gas mileage on the MP3. Tell me either A. Possibility B. Definitely not or C. Wouldn't happen and 1. Big factor or 2. Small factor:

Misfiring
Faulty return system
Those damn Bosch ****s
Bumper hanging (aerodynamics )
Allignment (Haven't done it since the swap, will do soon)
Bad battery, meaning more alternator activity
Bad A/C clutch
Just having A/C on way too much
Any of the other pulleys being bad
My ****ty ass shifting
Not having fender guards, splash guard, and deflector
Bad PCM

I'll try these first. I want to opt for an MP2, as I would like to have the wider ratio gears.

Default Re: P0300

P0300 misfire means either you have bad spark plugs, bad spark plug wires, bad ignition coils. start with the plugs, get rid of the platnums and get some plain old NGK plugs. disconnect the battery before you change them. if new plugs don't help, get new wires, if that still doesn't help get new ignition coils, if that doesn't help you may need a new ignition module which comes with coils on it.
