if it does, your maf is bad.
Also, the MAF is frequency based... so have fun with that.
The TPS is voltage but there is a notice thing from GM saying that the TPS may fail because the voltage spikes so quickly it throws the ECM off and causes a poorly running car. But at the same time, they say it can't be detected by a tech 2 scanner.... and if it can't be detected by a tech 2, i doubt you would be able to see it.
