hi all. just purchased my first mazda yesterday, a 2002 P5 with a ton of miles (187xxx) and a recently rebuilt engine. currently getting 3 codes:
P0103: MAF sensor high input signal
P0300: misfire
P0301: cylinder 1 misfire
other symptoms: car idles poorly (fluctuates and will dip real low well first started, shuddery. less noticeable after warming up); seems to lack some power when driving.
plugs, wires, MAF, cylinder 1 coil recently replaced (april). possibly O2 sensor? EGR? searched like a madman and most of the suggestions were the same (the things that've already been done). any guidance from you fine people will be appreciated. cheers!
