Engine Performance problem
1993 Mitsubishi Eclipse 4 cyl All Wheel Drive Manual 95000 miles
my car check engine light came on said o2 sensor upstream malfunction but before I changed it the car would run fine until it heated up then it would idle funny once the engine warmed and die on me every time I came to a complete stop it a 5speed manual. Now heres the weird part I changed the o2 sensor but with every new sensor I put in the car either wont start or runs like miss firing and idiling poorly cant even drive it why with every sensor I try it runs like worse but when I put the bad sensor in it runs fine before it warms up
have the same problem?
