For the past 2 months now i have been driving without my MAF sensor being hooked up. I replaced my intake with a AFE Cold Air Intake, possibly while doing it i damaged the sensor, so i bought a brand new OEM sensor hoping to solve the issue, but it still persists (i have already tried disconnecting battery for 30min to let ECU reset). So i have given up on that issue and am just driving on default fuel.

About a month ago i had a ignition coil go out. So i replaced that one coil as well as had them replace all 6 plugs (the ones in it before were autozone cheapies and were getting old. Ever since i got the car back i have had low idling at around 600 rpm with a slight trimmer (nothing extreme like when you have a bad MAF sensor or a bad coil). This low idle has occurred since i disconnected the MAF a few months backm, but since i had the coil and plugs replaced it will drop to as low as 200~300 rpm when breaking or turning and has stalled on me in intersections before. Now this is dangerous to me and others because power steering will nearly go out when turning and stalling in an intersection is just not good. So i would like to get this straightened out before someone gets hurt.

I was thinking of replacing the wiring for the MAF sensor to see if getting the MAF issue resolved will also solve this issue.

What has been replaced?: Car is at 127,000 miles.
Water Pump: 115,000
Starter: 120,000
A few hoses: 120,000
Cold Air intake: 117,000
Ignition Coil: 125,000
Spark Plugs: 125,000
I bought and tried a new MAF sensor at around 121,000, car went bad about a week after getting it back from the dealer for the replaced starter.

If anyone needs any more info let me know, i can also pull codes as well if anyone would like those.

Thank You, Andy

Need to read those codes. Many things could be happening.

Immediately I thought Vanos but reading codes would be a more direct approach.
