Thanks for the great info!
One thing you missed. The P0300 error can be caused by a bad MAF or Mass Air Flow Sensor. I had a problem with P0171 and P0174 errors and cleaned the MAF sensor. I reset my codes and it ran fine for a couple of days, then I started getting P0300 errors and other related error codes, and performance sucked. I talked with a friend who owns a repair shop, and he suggested the MAF had failed. I changed it, and now it runs better than it has in years.
Hi need help on figuring out what can be the misfire on my 2005 dodge neone I already changed out the spark plugs spark plug wires the air filter and fix a vacuum leak what els can it be any answers
It could be a bad coul. Or bad o2 sensor. What kind of codes are u getting. If not getting a p0050 or p0155 it's not o2 sensor. Another cause could be a bad ignition control module. But start by getting your coil checked first.
I also have an error code p0300 on my 20p5 dodge neon, its the only code. What worked?
Thanks for the video! Helped me figure out my car has an intake manifold gasket leak. Which apparently is common with the S series Saturns. Going to be my first time replacing one but worth it!
