My dad's car is a 2001 Bullitt.

So I get in the car with my dad today and I look over and the check engine light stays on. I ask him how long its been on and he says like 2 weeks or so. After we got back I took the car down to autozone to borrow the code reader. The code it pulled was:
P0300
Random Multiple Cylinder Misfire Detected

When I came back, I asked him how hard he was driving the car when the light came on and he told me he was bouncing on the rev limiter a bit and that he was driving it quite hard.

What I want to know is, can the car throw this code because he was hiting the rev limiter which caused the cylinders to not fire ? The car has actually broken a spark plug and Ford repaired it under warrenty. It is on its second set of plugs right now and runs just fine. Anything to be worried about or is this normal ?

Sorry, I forgot to tell you guys I reset the code while I was at the parts store. I drove the car home from the store and everything seems to be fine. It idles fine and power delivery is smooth. The light has not come back on but it was only about 2 or 3 miles of driving.

Why does my dad drive the crap out of his car all the time ? Because he loves to drive fast as hell and since he was a piece officer for like 40 years he doesn't have a fear of tickets. They always let him off and then harass me for making a U-turn or some bs when all I did was make a left turn from a waiting lane into a drive way or exabition of speed because my tires sliped on some sand in a parking lot. He told me he has been racing with the new 05+ Mustangs lately and hasn't been wining. Thats provably when he taged the limiter.

I was wondering if tagging the rev limiter too much at one time can cause that code to pop up.

On another note, the TO bearing and pilot bearing need to be replaced and while I'm there I might as well do the clutch.... 56000 miles and the TO bearing goes bad, that is just SAD. I wonder if thats a result of him beating on it ? I wouldn't think so tho, thats provably just bad luck.
 
i HIGHLY doubt it threw the code from being driven too hard


every once in a while i'll take my car to a dark corner of the streets and just unleash hell on her, never had one code


random misfire i'd start with the EGR system if it comes back

Ok, well we will see if the light comes back on but he did say the light kicked on right after he bounced the crap out of the rev limiter. My friend said I should put a shift light in the car for my dad lol.
 
Yea this does seem backwards LOL. The son knows how to work on cars and obviously drivers alot more sanely...wow. And its hillarious, a retired cop street racing :rlaugh: .

Around here, local DPS and the highway patrols are at odds. they LOVE giving each other tickets and have a little war going on. An ex cop was telling me the other day that in the local DPS meetings they would always be like "well they got another one of us....so make SURE you ticket any off duty highway patrol for whatever you can!" LOL.
On duty is a different story...they never mess with each other while both are in squad cars.

Anywho, the random miss fire code is tougher to sort out...so atleast you should be able to elimate a coil pack or spark plug as the issue. rev limiter seems possable...and I recal hearing something like that happening before. I guess he was just setting there getting a feel for the limiter....maybe he likes how it sounded haha.
