If you hit the HTTP the picture should be clearer.

Only one small thing jumps out at me. That's the IAC valve, which is bottomed out (0), with the idle speed about 140 RPM above what the pcm wants. Might be a small air leak somewhere. To see the most, we would need the log file.

You don't need the link really; we can click on the thumbnail to see a clearer image even though it isn't larger.

The inlet air temp looks very high. What was the ambient air temp?

The LTFT's in the idle cell (16) are subtracting fuel, and almost bottomed out. Could be an indication it's running rich. That would possibly negate the air leak theory. Could be your throttle blade stop screw needs to be backed off slowly, until the IAC counts get into the range of 20-40.

Coolant temp is also high. Was the car sitting, idling for an extended period?

Run a complete log.

Thanks GaryDoug. I'm a little computer challenged.It took me for ever to post this but I did it.I thought this was the log.My bad.How can I make a log.Guess I need a walk through.This is exciting to me,I just don't understand it all.Your contribution as well as Injuneer's and of course Shoebox (who saved me millions in repairs and has been here since the site started I think) invaluable advice and yours really makes this club great.Thanks again.

What you posted is a single "record".... a snapshot of a single instant in time. Typically, the software is capable of recording and saving at a rate of 8 or 9 records per second. That's just about how fast the ECM can update. To run a data log over an extended period of time, Gary will have to tell you what box to check in the software. I only look at the output data from the Scan9495 software. I have no need to run it, because I run an aftermarket computer with "built in" data logging capabilities.

Start recording, from a cold start, through warmup, driving moderately (typically about 3-1/2 minutes to closed loop). Then continue with a few more minutes of more aggressive driving, including at least on full throttle pull to more than 5,000 RPM. A 10-minute log will contain upwards of 5,000 lines of data, each line showing most of what is shown in your screen shot.

The software can produce a file of this data in .csv format. We can take that file and review it. I just use Excel for the review.

GaryDoug

Scan9495 is always collecting the data, but normally doesn't save it to file until you click on the light blue "Save scan to Log File" button. Or if you are forgetful, as am I, you can check the box on the Engine tab page that is labeled "Auto-save Scan File" and the log will be saved as you scan. However, this method will run slower than without it checked, so I would leave it unchecked and try to remember to click the button at the end.
The log file will be placed into the same folder as the program and will have the date, time, and VIN in the name with the extension ".csv".

Thank you.Will work with this tomorrow or next Monday(days off).

Fatdog2

Sorry,read this again tonight.Your right,I was sitting at a gas station parking lot trying to get this program to work and the car got hot and the fans came on.(about 70 degrees).Then I went for a run.

Fatdog2

70 degrees was the outside temp not the car.

Fatdog2

Postponed to next week.Got relatives visiting.But I will do this scan.

Fatdog2

OK , the relatives are gone now but in the mean time I've been addressing what might be air intake leaks such as a new grommet for the valve cover where the hose goes from the valve cover to the throttle body as it was loose as a goose.I tightened the screws(3) under the the throttle body(that was a pain)Iknow there are 6 but I gave up.I threw a clamp on the purge valve rubber L shaped hose just for kicks.It looks ok can't find them anywhere but a guy on utube used an old spark plug boot and it worked for him.I actually bought 3 grommets as I want to replace the pcv valve grommet (they look the same).I might replace the U hose as well.They are about $15.00 on up shipped.Anyway when I run a scan next week I hope it's a good one.
PS I tried to run the cigar test for leaks but I couldn't make that work very well.
Sorry for writing a book here.

Fatdog2

OK. Got a mule laptop from my brother in law and tried to download scan9495 with the frame work ,didn't work,so I ran upstairs to my wifes computer and burned the scan9495 to a dvd blank and tried to make it work on the mule but it would not work without the frame work so I tried to burn in the frame work upstairs and it didn't work so I ran downstairs to my windows 10 laptop and burned the framework ,uploaded it to the mule and now everything looks like a go for tomorrow.Whew.
The mule---10 year old compaq presario vista.
My laptop 1 1/2 year old windows 10--doesn't like scan9495 much
Upstairs tower windows vista loves scan9495 but not the framework.
I think I've got it dialed in.Thanks for looking.

Hope GaryDoug and Injuneer can read this for me and give me any thoughts.(Hope I did this right). On my first run I saved scan to log file but could not find it anywhere so I let the car cool down for a couple of hours but used the auto save this time.Thanks.
