2005 Infiniti QX56 Question: Running rough and stalling, will not stay running! Is this a Throttle body issue

a data showed the throttle body had issues. call a mechanic friend - he said to clean the mass air flow sensor first. which I did! it worked for about 5 minutes...still running rough and stalling. bought a new one and installed...whew problem fixed....for about 2 miles....back to the same problem. cleaned the throttle body-was not tat dirty really. started again and ran for 10 minutes still same issue. I cant figure out how to adjust throttle body sensor! I was told a new one cost $1200...WHAT? crazy! Can I get a used one at a junk yard? Can I just replace the sensor? Any suggestions would be great!!! Looking for a fast reply if possible. Thanks for the advance help! -
Answer 1
first, what was the code?? no, you cannot use a used one. no, you cannot justr replace the sensor. i would look for simple things like a vacuum leak. it may be as simple as that. start with the code Roy -
