Question about 1997 Mercury Cougar XR7
I ran a obd ll scan, come up with codes 155 161 1131 302 cleared codes and drove 2 miles same thing happened. some codes came up. The 1131 is fuel air metering. What controls that AIR valve. Has a lean problem. Turn key off, starts great then starts to stall again after A mile or so.
Try looking for engine vacuum leak,around the injector seals inlet etc.Is the air box lid and hoses tight and leak free?Could also be fuel pressure problem Try squeezing the fiel return line with the appropriate tool so you dont damage it and see wether the engine idles properly.If idles better more than likely fuel pressure problem.
