    Hello guys! Another issue I have with my fav suv. For a while I had cel codes p0171 and p0174. I’ve checked for leaks with carb cleaner around intake and anywhere it may be sucking in air and no change. I’ve checked fuel pressure with scan tool but it’s probably not as accurate as to mechanical gauge. I’ve cleaned the maf sensor, it seemed to help for a little while but light cane back on. So I ordered a new sensor online and installed it. Now I have all these codes p0171,172,174,175, and p0101. The sensor is nit from Land Rover, got it on eBay using part number from original. Drives great but every now and then it surges, and little rough on the idle when start. I don’t want to spend a butt load of money to take to shop. Has anyone had any issues similar?? Any other steps I should take?? before giving in and taking to shop. I only use premium gas. I have not changed the spark plugs, I’m the second owner so I don’t know the history of truck. Vehicle has 163k miles and even with codes on it drives strong. Thanks in advance guys
