1998 Oldsmobile Intrigue 3.8 V6.
Check engine light MAF circuit code.
Repair work done prior = new heads, gaskets, intake and exhaust
manifold gaskets... Almost the whole top end of the engine. This was
done about a year ago by myself and a professional.
Work done to repair this problem = new MAF and map sensor. Coil
packs and o2 sensors.
Question = The car has a really rough idle and at times bogs down.
This happens while the cars cold and after it gets hot with no change.
The code that comes up is a mass air flow circuit code. I put a new
maf on and it did not remedy the problem by any means. The wiring
seems to be good. And i have looked it over. I had the top end of the
engine done and it was running great, almost like a new car. But
about a year after that, it started to go down hill. I even put new
manifold gaskets on it and no change again.. I'm running out of ideas
and any help would be greatly appreciated. Thank you.

Tech JK:
Have you checked for power and ground on the MAF circuit?
Is the idle always the same, or some days different?
After clearing codes, does it run better, and then the light comes
back on?

Yes, the power to the MAF seems to be fine i ran through it all with a
multi-meter. The idle seems to always be the same.. I have also
experienced a loss of power while accelerating. The rpms seem to sit
low even with the pedal to the floor, while driving. While in park the
rpms will hit the rev limiter with no problem. When i clear the codes i
dont really notice any difference in the cars performance or idle.

Tech:
Well, there is more to a MAF circuit than just the power in. There is also
a ground and a signal. A problem in either of these will cause these
problems. A MAF circuit can act like a low fuel pressure or plugged
catalytic converter.
