The saga continues and I'm near the point of giving up and taking it to an indy and letting them try.

I read some stuff about testing the MAF for a bad ground so yesterday I was fiddling with the MAF and trying to get my
multimeter hooked up so I could test the ground in situ.

I used sewing pins in the top of the MAF harness to make the connections but something slipped and the
MAF ground pin touched (shorted) the Supply 12v pin.

I heard the throttle plate make a hard smack at the same time and feared I damaged something
with the momentary short.

I then started the car and the Egas throttle was unresponsive, although the car started and idled.

I checked all the fuses and they all seemed fine.

I reset the computer disconnecting the battery, no luck, still no gas pedal response.

I checked the codes and the Egas Potentiometer codes are now present with implausible reading,
as well as the throttle position sensor codes and the MAF code that was there before.

I hope I did not fry something.

I took the throttle body apart and looked at the potentiometer and it looks fine and does not smell burnt.

I'll need to find the Egas potentiometers next and see if they look OK.

I hope the ECU is ok, as the car runs and otherwise functions properly.
Just no gas pedal response.

I wonder if the ECU has its own fuses?

It still acts like the ground is bad for the MAF so I read that the C9 pin at the ECU is the MAF ground
so will check that as well.


I found these helpful but I need to add a DSO scope to my toolkit.
