OBD1 question

[Yahiko]

I don't usually see anything with OBD1
in it but a friend asked me if I could.

Will the Solus read an OBD1 car?
It's a 5.0L Mustang. I asked him to let me
know the year and what not so I could ask.
I think it is's a Fox Body but anymore and
I have to ask him.

Thanks for the help

Yes my old Solus with 6.4 was able to do OBD 1( with stock ECM) but you need the specific OBD 1 connector and battery clip power -lighter adapter cord to do OBD1cars. I hear you now have to go into Utilities menu to access those obd1 years of coverage on the newer updates though .

You should be able to perform KOEO, KOER, and Wiggle Test. Any available Troubleshooter info in the scanner will be valuable in this situation. Depending on the model year, there may or may not be access to live data. You will need the FORD-1A adapter and a power cable to attach to the adapter.

Cool, Just the info I was looking for. I have
both the lighter plug-in and the A1 adaptor.
He did note that the car is Mustang EFI 5.0 that is
running speed density. He says that it's never
been running "right".

Because I deal with diesels and aircraft I am going
to be a bit in over my head on this I think. But if I can
get any codes and data out of it then we will have a
place to start looking. He did find that the former owner
had removed the T-stat. Now it has one back in it and
that should help I would think. Did the EFI system run
closed or open loop?

Thanks

First 10 of the VIN, makes things so much easier. Once you ID the car, then you need to have the car in your possession. Find out if the car is stock. If it has mods all over the engine, I'm not even going to bother over the internet. Typical stock engine problems I saw were broken vacuum tubing, faulty/plugged vacuum solenoids, EGR valve/position sensor issues, and aftermarket secondary ignition components.

Are that any quick giveaways to if it been mods done?

Maybe donk wheels with the golden arches painted on the sides?, at least it would sit high enough you can slide under it to see if the cat converters are missing or not

Your first clue will be that some idiot has installed a K&N air filter on it. Hard to do much "tuning" on speed density engines. Headers will also mess things up, as will an aftermarket PROM in the PCM [engine computer]

[Yahiko]

Well I just found out that they removed the Kat replaced
the "H" pipe with an "X" pipe with mufflers and it does have
one of the cold air intakes on it. I will be putting eyes on it
on Saturday. Right now I have to work by email.

Two other things he told me is they put the stock distributor back
in and were not sure if it's timed right or not. The last part
is he thinks it's running rich.

On and lastly I found out that his brother had his hands in there
at some time. Oh My God. Worse than Red Neck tuning when it
comes to that dude.

I think I might need a little more than luck.

I'll think that I am going to go back to diesels and stay away from gas cars.

Wow! Try to find out if "Bubba" installed a hot rod PROM in the PCM [engine computer] Scanner may or may not communicate with an aftermarket PROM installed. Probably need to re-install the stock PROM. Sounds like you're dealing with "I'm not an auto mechanic, but I play one on TV"

Well here is the first 10 of the VIN

I would approach as follows:
Do your best to have the owner provide a precise description of the symptom(s).
Visual inspection under the hood without wiggling any wires or attempting any adjustments. Run KOEO self test. Record KOEO and Continuous Memory codes. Post any codes here.
If no codes present, perform KOER test. Post any codes here.
Use the Troubleshooter in the scanner.
If no codes, check ignition timing. If this 'Stang has the stock distributor, it will have an ignition module bolted to the base of the distributor with a major electrical plug connected. You will have to remove the SPOUT (spark output) connector to check base timing.

If Idling poorly, I Seem to remember the plenum gaskets, and sometimes lower intakes would have vacuum leaks, sometimes Egr valves wouldn't close all the way, EGR vacuum regulators would leak slight vacuum to the EGR valves and that would make for poor idle. Sometimes the TFI modules(Thick Film Ignition modules and stators of distributors went bad.

TFI just like in my OLD 88 Ranger. Grrr on that thing more than once.
Turned out to be a bad plug after I can't count home many tries.

I get some face to face time with in Saturday evening.
