Hi All, new guy here, just bought a 2000 ford ranger with 102K miles about a month a half ago . Recently the check engine came on and it had the following errors P1131 and P0171 I believe the first one is "main Cntl fuel air metering" and the second one was "system too lean bank 1". Took it to the shop and they replace the o2 sensor bank1. About a week later it came back on again with the same error, luckily for me there was a guy that work at advance auto parts (where i got the codes read) that had the same vehicle and he recommended that I clean the MAF sensor. I clean the MAF sensor and the check engine light was off for about 3 days then it came back on with the same codes. Is there anything else i could look for that would cause these codes, I tried looking for leaks in one of the hoses but I couldn't find any. Any ideas as to how to solve this problem would be appreciated.
