yea thats what i thought too....when the dealer replaced the MAF in Aug. i guess they must have broke the connector cause when i unplugged it this time to clean it the purple locking clip just fell off.....but all is well now....so i was wrong about k&n.....

 

p0128 = thermostat - it is jamming OPEN, leading to a below required temperature condition. Replace thermostat. And yes, when it fails the problems you have seen will be intermittant, and will disable the a/c when it throws the p0128 code. If the termostat was replaced in Aug, it should be covered by warranty.

 

yea i know...its a long story that i resfuse to bore this site with but its been a month and the dealer was supposed to call me back 3 times and never did. Plus they tried to charge me $115 to repair a broken pin on the compressor when i took it to them a month ago which was B.S. because i can always get a/c by pulling the fuse....and yea i can watch the temps go down to 160 on the highway and in traffic it only got to 174.....but now that i cleaned the MAF....everythings fine, LOL

 

2nd time cleaning the MAF has helped the temps go back to normal.....
