my 95 millenia wont start. it had a code p0300, random missfine. i filled the gas tank and added drygas hoping i might have gotten bad gas. i reset the computer and car was fine for a while. car lost power and barely limped home. got codes p0300, p0154,p1173 and p1345.
i reset computer and car still had no power. i drove around the block to see if i could drive car enough to make it to work next day and car died. got codes p0300, p0725, p1364. car will not restart. i am sure there must be a logical path to follow th find and fix the problem or problems but i dont know where to start. car has 124,000 miles and got new plugs, valve cover agskets and timing belt in september. it has been running fine till now.
any help will be greatly appreciated. jim
