ok so i went to do a oil change on a friends 2001 ford taurus.its a v6.now we change the air filter and 3 of the 6 sparkplugs( started raining).now when we went to turn the car on it wouldnt even crank.i thought it was the battery so i jumped it and nothing.then out of nowhere it started up perfectly but when we put it in reverse it shut off again.im so confused.could the the mismatched sparkplugs be causing this?or maybe the maf needs to be cleaned?
