Hi Mustang Lovers!
Recently, my uncle bought an 1990 LX 2.3 Mustang...
This car was "abandoned" for 6 years... the transmission was outr of the car (and out of order... and the engine didn't start)...
Well.. we are slowly making the car look like a Mustang again!
we are having some problems that us ant ANY MECHANIC here in brazil (for you to have an ideia, there is ONLY one examplefor the 2.3 Mustang in Brazil. so mechanics DON"T KNOW this car.. and besides.. there aren't any good mechanics here...
We are having a problem that is driving us crazy...
when the engine is COLD, the car runs good for about 5-7 minutes... after ir heat a little bite, the engine "fails"... it seems that the is EXCESS in gasoline line...
We've already changed: Fuel Pump, Fuel Line, Engine coolant temperature sensor, Spark Plugs, Spark plug wires, Fuel Pressure regulator,fuel injectors and we can;t see any changes...
Other thing, is that is very hard for us (i have an 1995 GT V8 Mustang) to buy parts for the car here in brazil... mostly o buy on E-bay and they delivery it to me...
I don;t know what else can i do do ake ths car runs good..
Can someone please give e some help or does anyone had this problem?
Thanks and sorry for any english mystakes!

Do you have anything like an Autozone or Advance Auto Parts in Brazil? You should either check or replace the ignition module and see if that clears up your problems. When the module gets hot, the car dies and will not start again until it has cooled off quite a bit.

I don't know of any way to check the module without the testing equipment at the parts stores and even then they can show the module to be good if it's cool when tested. Might be better off to replace it, if I remember correctly they aren't very expensive.

Thanks for the help... I'll try to replace the ignition....
Unfortunaley there aren't AUTOZONE nor Advanced nor NAPA autoparts here in brazil...
Being sincerely, all parts for Mustangs here in brazil we have to buy in USA(yes.. we sometimes travel to buy parts at autozone or advanced parts) or e-bay..
There are stores that can provide parts for american cars here in brazil, but, for you to have an example, if i need to change the spark plugs for my 1995 GT V8 Mustang, the price of the set (8 spark plugs) it will be around U$220,00! at autozone i can buy it for las than 50 bucks!
I'll try to change the ignition.I'll check if there is anyone of any brazilian car that fits this mustang 2.3! Thanks for helping!
Any other ideas?!
Thanks again!

The ignition module used on the 1990 U.S. 2.3s was the TFI that was attached to the distributor. That module should be the same as used on nearly all Fords that used the TFI ignition. You may have a good chance of finding that module on a Brazilian model.

I'd also look at the ignition coil. A bad or weak coil can fail when it warms up and because of the misfire, it will look like a rich fuel mixture. You'll get a little black smoke from the tail pipe and black soot on the plugs. It may also backfire through the exhaust due to the raw fuel being pumped into the pipes after a cylinder misfire.

Thanks again!
My dad is in USA, and he phoned me yesterday.. I asked for a new ignition module and he already bought one at local autozone... (i wish threwas one autozone in brazil...)
I've already rtested another coil (the coil used in this mustang is the same of my 1995 GT V8 and there ate some other cars that use the same coil here in brazil (VW SANTANA, VW GOL, VW VOYAGE etc...)
Thanks again for the help!
I hope this time the car runs good!!!
The story of this car is a long one..
It's been "abandoned"for 6 years since the last owner died...
Since then, it was stoped in a small city and no one could fix it..
When we bought the car, it was with the trasmission (A4LD) in the TRUNK!it had a broken Flywheel.... now the trasmission is ok.. the engine is starting (there was a problem with the starter relay), the fan is working ok (it was with a broken wire..)
There are more things to do on it.. but the main one is to make runs good!
Thanks again for the help! if anyone needs anything from brazil, just let me know!

I hope we're helping. Keep us updated on your progress.

[thico]

You are helping a lot!
I wish i'd live in USA.. everything about CARS here n Brazil SUCKS!!
Brazilian peope just drive 1.0 Liter engie cars with 80HP! and the mechanics don't know about "good"cars!
My dad arrives on friday.... maybe on saturday i chenge the module en see if my problem goes away!
Thanks again!

[b_chandler]

You realize your '90 Mustang's 2.3L engine only puts out 88hp at the flywheel right?

[thico]

I knw it's just 88hp..
But.. we have plans for the future... Turbo charge this 2.3 engine... OR.. change this engine to a V6 3.8 from an 1995 V6 Mustang...
There's a guy here in Brazil that crashed his V6 Mustang 3 years ago... and since then, he is not paying the documents for the car anymore..
or he sells his car in parts or to an autosalvage.. but no auto salvage in brazil buys Stangs... (the don't have people to sell parts..)
My and my uncle are thinking about buying this car to take out the engine and some other parts to put in this 1990...

What do you think!? is it a good idea!?

Thank you!

[b_chandler]

I don't know if I'd want the V6. I personally never liked the 3.8. There's some good parts that can be had from that car. The brakes, rear axle, seats and a few other parts will swap over with a little work.

[thico]

Nice!!!
What else can i remove from this V6 crashed car?!?!
Why do you prefer 2.3 than the 3.8?!
I thought the V6 was a little bit better....'but.. i'll search more about the 2 engines...
Anyone else have more opinios about putting the V6 3.8 engine form a 1995 Mustang in a 1990 2.3?!

Thanks!

You mentioned replacing several items already, but I didn't notice Oxygen Sensor on the list of parts. Since the problem you are having happens after warm up, it could be a faulty O2 Sensor. I don't think the O2 Sensor plays a part in the fuel delivery as the car is warming up, but after warm up the computer expects an input from the sensor to help control fuel delivery. Anyway, its something to check... Good luck!

[thico]

Thanks!
I'll change the ignition control module that my foather already bought...
And then... if the problem persists... I'll check the O2 sensor!
Thankas again!

[thico]

I talked to m uncle and he said he has changed the O2 sensor.. so.. it was not the O2 sensor was not the problem...

We changed the Ignition Control Module and the car is about 99,99% good (sometimes, just when you press hard the accelerator, the cars "wants to fail", but he doesn't fail at all (i don't know how to explain...)
One more thing.. one mechanic rebuilt the automatic transmission of the car, and we saw the he OVERFILLED the transmission OIL... is this might causing problems in the car?

We saw that there is a conector that gos INSIDE the transmission (that we don't know what is that) thas is CUT OFF...
We conected this wire and there is a SHORT circuit on it (it gets fire!!!, so we kept it disconected..)
Does anybody know what conector is that?
Thanks again!
