I've researched old posts but still have a couple of questions:

1. Two or three months ago I replaced the MAF in my 92SE and it corrected the problems I was having. A month or so ago I replaced my air filter. A few days ago the car again threw a Code 34. I pulled the MAF and cleaned it with a q-tip but it still threw the code. Should I try using a cleaner? Suggestions? Or is the MAF likely just defective? I can't believe it would go out so soon otherwise.

2. A couple of weeks ago I put 4 new tires on because we had to make a long trip involving mountains and LOTS of snow. I must say the old Bonneville handled beautifully in the snow and I never had to chain up even though we drove on snow for several hundred miles. I did, however, notice that the traction control light on the dash started coming on. The light on the switch by the shifter has not worked for years and I have never been able to tell if traction control was on or off. We recently took the car to get an emissions inspection and they could not test it because the traction control would not turn off. Any suggestions?

Thanks in advance for any and all help.

Well...it is possible that a wheel speed sensor has gone bad...check connections on all four wheels...is ABS light on also??

Is it just throwing the code, or is it actually acting up? You may need to clear your PCM.

I have not seen the ABS light come on. Would a bad sensor cause the traction control to stay on, as opposed to not coming on?

I have not had it act up, but before I cleaned the MAF, my wife said it was acting like it was having trouble shifting. Unfortunately, she has described every problem we have ever had with the car the same way. I suspect it may have faltered when she accelerated.

Traction Control...comes on by default when you start the car...If light is on in the dash...then TC is actually off.

Ice and gravel buildup may have 'blocked' the wheels speed sensor in one hub. A good wash job behind the wheels may be in order.

If TC is turned off or faulty, the light in the dash will illuminate. If you need to disable it for emissions testing (???) disconnect the large connector under your airbox that goes to the PMV assembly.

Willwren: Apparently DEQ cannot test the car if the traction control is on and, for some reason, it wouldn't turn off while they were trying to test it. Thanks for the info re disconnecting it.

jr's3800: Will have to check when I get home. A parts store ordered it for me but if I recall correctly, it looked exactly like the old one.

Willwren: disconnecting the large connector turned off both the TC and the ABS. I will disconnect it just for the DEQ tests. Apparently they raise the car and check at a certain RPM while the car is in gear. The TC interferes with this because it senses the wheels slipping.

jr's3800: The MAF is reman. Anyone have any suggestions?

Forgot to warn you about that

If you disconnect either the PMV or the EBCM, both ABS and TC will be disabled, but normal braking will be unaffected.
