ASE or Ford Tech HELP needed PLEASE.....

Below is the recorded data from a 2003 Ford Ranger Edge 3.0 FFV V6 2wd. The truck seems to run great but idles like crap. The idle is rough and seems to have a miss. This data is after new Autolite APP103 (factory equivellant) sparkplugs, Autolite Professional wires, Cleaned MAF, Coil is 2 months old and was also metered out OK, seafoam thru vac line prior to plug change, and I have run Gumout Complete Fuel System Cleaner for two consecutive tanks.


I can not find any vacuum leaks and the vacuum holds a pretty steady 18-18.5 in/hg. The upper intake gaskets were recently changed and made no difference at all.


The battery and alternator are also new.


ALL the data is at idle with the engine up to operating temp and the transmission in park.

Yes, the entire throttle body has been completely cleaned out. It has a miss I can not pin down.

Looks like it might be on its way to the dealership. It has been overheated and has new head gaskets and the heads were sent to the machine shop.

I think it may be low compression due to stuck rings or something. Although the compression test was OK according to the specs Ford provides.

2003 Ranger 3.0l flex. 54000 miles.

Idle vacuum 18in.

Compression

The fuel trims look pretty good from what I can see. It's pulling some fuel back, so I don't think you have a vacuum leak looking at the load values and the TPS values. Have you seafoamed? It looks like it was fully warmed up... how does it idle under open loop conditions? (when its super cold)

fuel trims seem a little on the negative side for what im used to seeing on 3.0s leading me to think you have a leaking injector or a sticking injector. is there a way to do a power balance test on the scan tool you are using? what scan tool are you using? because if you could do a power balance test to see if you have one cylinder dropping off or random/multiple cylinder dropping off

-3% is pretty minor - don't you think? I don't see that causing the problem.

yeah it is pretty minor...most 3.0s i see the long term is about 7-10%

id like to see a power balance test done on it with IDS or something similar to see if it is missing or not because all those PIDS listed look fine to me

power balance test - or just read each plug

most of the 3.0s ive read, including my own are pretty high...i think mine was like 3-4%

not sure how well you could read the plugs for an intermittent mis fire though. if it was all one cylinder i see how you could detect it

From the factory, 3.0 Duratecs had an even smaller percentage, -2.25%, on one bank compared to the other. When Venom tested a nitrous kit, 50-shot, they totaled the engine. A friend of mine ignored the warning on his Mazda6 wagon and ended up destroying the plastic UIM in a small explosion, still got pictures of it somewhere.

The problem with the Duratec was the EGR tube protruding into the UIM, blocking air flow into the rear bank. The Vulcan has no such problem, so a 3% imbalance between left and right banks is a serious issue.

His oxygen sensor voltages also verify the rich condition.

It should be zero

Based on the replies from here, the general concensus is it is running rich?

I can not do a power balance test with the scanner I have. ACTRON CP9180 I think. It will do freeze frame data and drive cycle monitoring and such.


Here are some other recent test results:


2003 Ranger 3.0l flex. 54000 miles.

Idle vacuum 18in.

Compression

cyl1 161
cyl2 156
cyl3 160
cyl4 160
cyl5 146
cyl6 165


According to the specs that FORD puts out, this is passing. But, It sure looks a little off.


This engine was massively overheated and driven till it died. The upper radiator hose came off the thermostat housing and dumped the coolant. It was dark and rainey so I could not see it and the temp guage did not rise due to the fact the coolant was gone. The head gaskets were replaced and the heads repaired at a machine shop, all under warranty by the Ford dealer.

I suspect the rings or cylinder walls are coked up or damaged.

Dude - the negative fuel trims tell you how much fuel your closed loop system is pulling. If they were positive that would mean that it is dumping in more fuel.

OK- Lean then????

I am trying to learn this. Some of this is Latin to me.

Sometimes I need things dumbed down a little.

I did an awesome post on code trouble shooting and fuel management tricks but the mods never stickied it!

Sadly the 3.0L Ford engines always idled like crap. That was the downfall of the Vulcan. But when you put the pedal to the metal they go! I mean really GO!

Negative fuel trim indicates fuel cut, the PCM is attempting to correct a rich condition.

If it was lean, the O2s would be reporting less than .4XX volts.

Well this morning it was off to the dealership. They are doing a power balance as well as a mechaincal compression and vacuum analysis. I will find out tommorrow what the results of the tests are.

Here is the compression numbers from 1 month ago:

Compression

cyl1 161
cyl2 156
cyl3 160
cyl4 160
cyl5 146
cyl6 165

The dealer did say the misfire test came up positive for cylinders 2 and 5. The two lowest cylinders. We will see what the new compression numbers are tommorrow. So far that is all they did. I don't know when they got it in to the shop to start work. The did do all the standard computer checks and that is where we're at now.

I replaced the TPS but no difference. Throttle cable is not binding or holding it open. TPS is not adjustable.

Got it back from the dealership and was told nothing was wrong. All readings including mechanical compression check and power balance are in spec. Maybe they just idle a little rough. When you give it gas it goes like a bat out of hell. So could just be the nature of the beast.

I was told the fuel trim readings specifically were excellent, so I don't know. They said it was definately not running rich.

They did put in new plugs at no charge, just to rule that out. AGSF-32FM. Those are what they said were called for, but that is different than the owners manual, AGSF22PP.

I suppose I will just drive it and keep an eye on things.
