MAF Connector Issue
 
1 Attachment(s)
This doesn't look right to me and I need help fixing this issue. My car runs sluggish at operating temp. However for the first five minutes of driving it runs like a champ no sluggish movement my voltimeter reads 14 and as a drive along it get's more and more sluggish until I hit 12 volts moving and sometimes 10 at stop lights. I believe that my MAF connector is the issue

I've already cleaned the MAF and changed the air filter and disconnected the battery. None of these things helped me out.

At exactly what point in the wiring is the voltmeter connected? It would appear that you are reading battery voltage, If so the alternator or associated circuit is faulty.

Yeah it's reading battery volts, I just thought that this connector might be the reason I'm idling so rough. Any ideas?

Yes I have ideas. :D

N.B. i.e. presuming that you are reading voltage from MAF connector terminal (1). --- The alternator bearings could be binding, an internal short circuit, or whatever.

MAF terminal (4) should register a low voltage of say 1 - 2 volts at idle, this being the signal circuit. Terminals 2 & 3 are ground connections. Terminal (5) is not used and this will enable you to determine the numbering sequence.

No more ideas, sorry. ;)

Thanks Trevor I actually figured that out a minute ago. So this may be an alternator issue. Should I just get a new one or fix that little sucker my self? I just want my car to run healthy :(

Your choice. :D

Depends on your electrical knowledge and mechanical experience. You will need a fairly hefty soldering iron, and if as it appears likely, the bearings are shot, a puller. If the armature is damaged, you can write it off.

An exchange reconditioned unit from a reliable shop, is a good bet.
