When you clean the EGR (a dentist pick works good for that)get a screened replacement gasket from the help section at your local auto parts store.I will prevent carbon build-up from getting in there again.No grounds codes aren't in there,so it is reasonable broken ground would cause this.Keep in mind that first code is normally causing the others.So after fixing the ground issue,be sure to clear all the the codes.

well I ran new ground wires on both sides. Little bit of difference. But not much. Egr looked good cleaned it anyway. still not running the way it should I checked so see if I have any wires in the bell housing Not a thing. You Guys think that the cats would be the issue. Would that make the tac jump when its idealing

You really need to adress the P0102 and P0113 first, unless you generated the codes by having the MAF unplugged.
It will not run well with a defective MAF or a MAF that has no power to it.

Maybe unplug the negative cable at the battery to clear the codes, then see if they come up again when you start it up . If they do, I'd recommend pulling the MAF and cleaning it with a sensor safe cleaner...they have a cleaner specifically for MAF sensors at any auto parts store. See if that helps

P0102 is actually a Circuit problem. Cleaning the MAF...although a good Idea wont fix it.
I have seen wiring problems as a broken connector, blown fuse and such cause the issue. It will also affect the transmission shift points and throttle pressure as it is controlled by readings from MAF and engine rpm/load and throttle position.
Also , unhooking the battery wont clear codes on OBD 2, it will clear the radio memory.

Latech, so you believe it is either a bad wire, a short or a bad connector? I've run into that in the past. I just questioned the MAF because I understood it was running fine when parked 4-5 months ago due to trans problems. You are probably right though...these modern electrical issues are not my forte.

That is what the P0102 is refering to...a circuit problem.
Certainly is an avenue to pursue first.Blown fuse, broken wire( B+ pink to MAF I have seen several times) , Defective MAF.
Cleaning the MAF is allways a good idea. Contamination will register a lean reading.
As long as the code is bonafide and not accidentally induce by technician, that would be the place to start.

A VSS would effect it all.Common to see the speedo doing stupid things when the VSS isn't working correctly.

The engine performance wont be affected by a Defective VSS. The trans on the other hand....
The speedo can jump around on that particualer vehicle while the thing is in PARK no less. Usually a cluster problem, or a ground problem, mostly the cluster at least that I have seen.

Thanks Everyone for trying to help me with this truck. When I pulled the transmission out to have it rebuilt I did notice all of the bolts on the bell housing didn't have any studs on them. I don't know if its because its a 5 speed manual transmission if that is why or not. my obd2 did clear the codes because I have a code reader. I ran 8 gage wire from the frame to each head made a difference. Not popping anymore. And its charging the battery. Before it would always discharge. But still running a little rough. But not like it was. I will drive the truck and see if the codes come back. When I unplugged the MAF sensor It quite. Once I plugged it back in it stays running. How do you clean the MAF. I will check the wiring with my test light or my ohms meter. let you all know what I come up with. Also check Fuses. Yes when I parked it. It ran fine.

Thanks
Tommy

MAF sensor cleaning is easy. Unplug it, remove it, use a MAF spray cleaner to the inside of it...you should be able to see a small screen inside it, just spray it down good. Any dirt or debri on that little wire in there will cause it to read incorrectly. Just the spray, dont try to wipe it off or use a brush to clean it. Bolt it all back together and see if you have improvement.
