The Po101 (MAF) Sensor came on - I replaced it. The P0106 (MAP) sensor came on and I replaced it. The P0101 came back on and repeats after being cleared. I have also checked the vac hoses, cleaned the TB.
Problem is erratic idle (varies 800 to 2200) and at 30/40 mph I get a humming sound like from a turbine. Also misses at 55/65 (short cough). Any help appreciated.

Check for a vacuum leak at the rubber coupler between the TB & manifold.

Thanks Ranger I will check it as soon as I return from overseas. LEft the car at the airport. Will be back next Sat. Really appreciate your assistance. You have helped me a number of times. Hope you are right. Hard to believe one little thing like that could cause so much trouble but would really like a cheap fix Ha ha.
