First let me say I am sorry it took this long to get back to you. I bought the Analog Multi meter. I was busy Ice fishing all winter and never needed the truck. SO I tested this multiple time and can only get 2.8 Volts at best. It didn't jump around and was smooth with the throttle. I also tested the MAP sensor and it tested out at just over 5 volts each time WIth wire connect middle pin and unconnected 3rd pin . Both read the same. So I guess it is good.
Question is the TPS only measures the 2.8. WOuld you say it is bad? Thanks for any help.

 

Is the 2.8 volts on the supply wire, or the signal return wire?

 

It is the Center Wire like you told me to use.

 

If you are only getting 2.8 volts at wide open throttle, thats bad.

 

I will change it out and hope that is what caused the sputtering. I took it for a drive the other day to pick up another small boat and it sputtered 11 times in the first 5 miles. TOtal of 25 miles and it never sputtered after those first 5 miles.

 

OK went for a ride of about 20 miles and not a single sputter. Pulled into my drive way and the check engine light came on. Po300 po301,302,303,304,305,306,307 and 308. WHat the heck. That means every cyclinder is misfiring. The truck ran pretty good and I never felt any misfire. Now what?

 

One more note to ad. I remember this happened last year and I forgot about it. It is that the Volt meter would drop down and then go back up. As in the Gauge on the dash, I thought I was going to have to change out the alternator but after messing with it I found it was a wire that once moved the volts would go back up. Either a fraid wire or loose connection I guess. Never looked into it much. But anyway it did this again on my trip and back.

 

OK went out and tested battery. It was 12,58 then I was looking at that wire that last year would make the Volt meter to go back up and my truck is under a carport with little light. I saw sparks or something lighting up inside the alternator. I moved the wire 3 times and every time I saw the sparks/Lighting up whatever. If it isn't one thing after another with this.

 

When it rains it pours repairs come in groups always in old autos.

 

Just wanted to say Thanks to you HeyYou!
