Since I have never heard of bugs in gas-does stabil which is suppose to keep gas good for along time have an exterminator agent in it?On a more serious note I think I would add stabil if my truck was going to sit for a long period of time. Just a thought.

 

Some of the diesel fuel additives have stuff to retard growth of bacteria. Are we talking gas or diesel here? There is a big difference in the two.

I got the innova 3130 on amazon for 125. With overnight shipping and yes it did come the next morning at ten am, it was 146.46. It does read live real time data but it does not read fuel pressure. Or I have not figured that section out. Only had it a few days now. I looked at them on innova's web site and then bought it.

 

was this problem ever resolved ? if so what the heck was it ?

 

guys i have the same problem 2000 e350 6.8l v 10 its in a shop wright now i tried a mass air flow sensor, fuel filter drained the the ran with seafoam no changes the fuel pressure is fine removed catalytic convertor none of this fixed it the tech is going to put a knock sensor on it keeps putting that code and p0171, p0175, p0326 and p1000.
this is a rv and it sat for a while aswell i did notice signs of a squirell in where the knock sensor sits so this may be it i really don't have my hopes up until it is fixed i'll let you know if it is fixed hopefully tomorrow.

 

Hey Guys,
Need some more help / advice.
I just got my Innova 3130 and went for a drive.
I need some help interpreting the data.

On the surface it "looks" like both banks are not on the same page.

1) Can anyone post or email me data from a perfectly good running V10?

Here are some observations that seem out of line (but I dont know what "normal" is so they may be normal):

I took the following readings Cruising at 50 mph steady state (wife driving).
Calc Load 70-75%
STFT B1 -3
LTFT B1 -6.2
STFT B2 -2.3
LTFTB2 -3.1
SPARK ADV 23 - 32 (varied depending on grade)
MAF floated between 7 - 8
TPS (around 30%)

O2SB1 (V) .160 - .815
STFT B1 S1 (%) 0.7
O2S B1 S2 (V) .770
STFT B1 S2 (%) NA
O2S B2 S1 (V) .810
STFT B2 S1 (%) 0.7

I tried to record for later playback during a pinging event, but of course the cheap chinese batteries that came with the tool died overnight and I lost the data so I am going to go do it again.

Its much harder to direct the wife to load the truck at the appropriate times haha.

So now I'm at least seeing what the truck is doing.
It looks like the Knock sensor is trying to work.

The one BIG thing that is bothering me is the TPS.
At idle (closed throttle) the TPS reads 20%.
At WOT it only reads 93.3%

On my race car when I look at my sensors through my computer my TPS reads 0 at idle (closed) and a full 100% at WOT.

Is that reduced scale normal for a V10 or do I have a TPS issue?

It also seemed a little odd to me (being a novice) that the calc load at part throttle 50 MPH cruise was over 70%.
I dont know what that should be, but on the surface it seemed odd.

So there you have it, next step in diagnosis.
Anyone have any insight on what to look for, whats normal, whats abnormal?

Thanks so much & Happy Holidays.
Cheers

I was thinking the same thing when mine started to act up there was some resistance when pressing the gas pedal down. i told the tech that he is supose to look into that today along with checking coolant temp senor before he installs a knock senor ill let you all know when i found out.

 

Same reader at 45mph on cruise ld recorded, calc load:18-45,spark:19-34, tps:21-28, maf:1-5, I am printing the freeze frame live data. It gives only first frame. pm your e-mail to me and I will copy and paste it for you. It looks like your data is similar only seems really restricted. ie the load calc. Also i get 21.1 on tps when idling and 94.1 on wot. Again yours sounds ok. My guess would not be tps. Your o2s seem to be working right also. Maybe try a record and then do wot. That freeze frame might give more info.

 

Also, All twenty frames on mine at 45mph ltft was 5 to 10.8. Never negative. It looks like you have written a negative on those. Did your vss read what you were doing? My speedo is off by 1.5mph in comparison to the 3130.

 

okay knock sensor did not fix the problem.

 

Thanks.
You confirmed what I have been thinking.
I spoke to 5 Star Mike today.
My Load Calc seemed way off to him as well.
Mike said that was pointing to MAS.

During my fuel pressure drive I was getting a solid 70-80 Calculated Load, and right around the pinging it was 95 or 96.
This was at an indicated 55 MPH, climbing a slight grade, in OD, empty truck.

As an update to the trouble shooting...
I just hooked up a mechanical fuel pressure gauge and drove the truck.

Looks like a rock steady 38 PSI, uphill and down, steady cruise, WOT and pinging.
So I assume I can cross that one off my list.
I was expecting a dip when asking for alot of fuel but its very steady.

OK so what seems to be way off is the Load Calc.
What drives that, the MAS?
Or what would cause mine to be so off?

At idle, foot off the gas coasting mine is almost 50.

Thanks for your continued help.
Cheers

Yes, my LTFT are negatives.
Hmmmm.
Does that mean its pulling fuel out?

I wish I knew more about how to now use this information.

I didnt think about comparing speed readings.
I will do that.

Thanks again.
Cheers

okay jimmy both are vehicles sat up for weeks and have the exact same trouble my technician thinks that the valves are sticking so he has put tranny fluid in the intake and gonna let it sit overnight hopefully this is it he said that there is a lot of pressure blowing out ? that is what lead him to the possible sticking valve i'll let you know tomorrow what happens.

 

Wait, what will the tranny fluid do for the sticky valves? Does he put it in while it is running? That might explain your negatives on the fuel. If the valve is shut there is no air so no fuel needed. Would explain back pressure on maf but why high vol readings? I thought the maf reads amount of air vol going across it? I know it heats to 200 and then the air across it cools it and..... but still. OK, back to the cd's.

 

If your "technician" is throwing ATF at the problem without doing a compression check in the first place, well, he ain't no "technician"...
