i am having a problem with my g6 that is starting to be real annoying. my engine light comes on and i used a scan tool to see what was wrong. i got the code p0102 maf or vaf sensor low input circuit and it check to see if my wiring the mass air flow sensor was gettin proper voltage and good ground and it was so i decided to chage the maf sensor. and i used some plastic epoxy to mend a little hold that i found in my intake tubing. i did all of that and cleared the code with a scan tool. and the idle is still not consistent and jumps up and down a bit but no to much. maybe about 100 to 200 rpm it isnt noticable on the dash but u can hear it in the engine. and a couple minutes later after clearing the code it came right back. could someone please tell me what is going on because i felt like i wasted money buying the maf sensor and that did not fix the problem.
