having a problem with my car- P0300 misfire
 

eerrrrrr it cost me 3 days of downtime already.. threw a code for # 4 coil being bad. replaced it. now it just says P0300 misfire. but it doesnt say what cylinder or anything.. its pissing me off. something which i thought was gonna be a simple coil replacement has turned into a mystery and im supposed to take a chick out tonight for her birthday!!!! helllppp meeee pleasseeee

if its misfireing, that cyl. should be runing cooler than the rest. u could use an Infrared Digital Thermometer to find the cool one. just measure all the headers in the same position, it will be dramaticly colder, ive had a simmilar problem and this worked great for me
good luck Justin

haha i actually just took home one of those thermometers from work to check my coolant temp cuz the gauge blows

you sure that code isnt just leftover from before? did you clear the codes out?

yup i cleared the codes and it was still runnin like *****. i changed 7 plugs out so far, the rear pass side one is a real PITA i dunno what im gonna do about it
