PO734 error code

[hywy61]

Transmission did a big jerk (only once) and then this code comes up. Hitting the road this weekend and don't want problems. I heard this could be a MAF issue?? I just replaced the MAF but with a used one. I have a bad feeling it was one with many miles - only lasted about 7K.

Any ideas. Truck is driving totally normal now.

How to reset that light ??

2000 DII - 63K

thanks

This code is a common one that points to an MAF error.
Have you tried cleaning the MAF with electronic parts cleaner?
I was getting the occasional error code until I did this.

I attempted the disconnect method to no avail but did not turn on the headlights....so will try again. thanks

drove about 600 miles

this weekend with no problems. Light went out by itself and now coming back on. The transmission did not jerk again at all like the first time so i am praying this is not a transmission issue.

Anymore advice on this one?
