Car runs and idles terrible after our exploding intake fiasco. Checked the timing and swapped out the plugs. Question is when I unplug the MAF sensor the car runs better, is this a symptom of a bad MAF.

Did the car ran for a while with the MAF unpluged ? It's my case and since I repluged it , car runs like crap too. Is this because the computer is relearning ? MAybe runing with/without the maf had screwed your ECU operation like it did with mine ...

No the car just runs terrible with the maf plugged in and will not even idle, with it unplugged it is better but still not great. I just tried cleaning the mac, unplugged the battery but still runs lousy.

Is a code reader going to tell you if the maf, o2 sensor etc have gone bad?

have you any way of monitoring the maf output ? like a sct tuner or code reader with live streaming ? You could see if the signal is OK. The bad idle issue could be caused by another sensor/faulty part. If the ecu switches into a different mode when you unplug the maf,it could compensate for the bad idle (like going into a safety mode). Just giving my thoughts...
