TOYOTA CARINA II - 4A-FE engine problems

[oldtoyota]

After 16 years of non problems with my Toyota Carina II, yesterday a had a
suprise.

I have started engine as usual, and after 200 meters of drive, it losses
power, when I press gas pedal engine wont go over 2000 rpm, it blows
into airintake system, when it finaly gets over 4000 rpm it's a little bit
better but it's still far from normal work.

I went to my mehanic, he cheked out catalisator system wich is clean,
sparkplugs cables and distributor are also ok, gas and air filter are also clean,
timing belt is o.k, from outside looking engine everything seams o.k., but dose
not work !

I want to say that until that moment engine has worked perfectly (for the
last 16 years) and in one moment - click, and it's not working.
I have made 150 km since last gas station filling, and I presume that it
woud made problems imidietly after 10-20 km if the fuel has dirt or water.

When engine gets warm, at idle is working o.k., but when I give gas
I get this blow into air intake system.

What is for me to do ? There is no Toyota service in 200 km radius for
repares or diagnostics ....

Any ides ? I pay a nice dinner and a beer anwhere for help !

With the transmission in Neutral [N], can you rev the engine past 4000 RPMs without latency?

[oldtoyota]

In neutral i get very hard at/over 4000 rpm, it stalls arround 2000, after 4-5 trys it goes at/over 4000 rpm but it drops down by it's self.

does it have a mass air meter?

Ok. I just wanted to rule out possible transmission problems. I agree with fredk; it could be air restricition.

I would try to get diagnostic codes from the OBD computer. on the Gen2 Camry's it's done by jumping terminals on the 'Diagnostic' port in the engine bay. Not sure about the Carina

[oldtoyota]

It has a manual transmision so it's has notihing to do with that.

Can you get a reading from the computer on the car? It should give you a code (the "check engine' light will flash on the guages) to tell you what the problem is. Do you have a repair book/manual for your car? It will tell you how to do this.

[oldtoyota]

After 3 days of checking everything on the car still no results.

Since now it has been checked out:

-distributor and cabels
-spark plugs
-air intake system
-belt

Still without any results.
The engine is working or better to say not working, terribile
it blows back in the air intake, don't want to rev when gas pedel
pressed.

I have found Diagnostic Trouble Codes, and the only thing is that
I don't get any error when i do the test. Engine light is normaly on,
without blinking or other.

Most intrested is that everything happend in one moment during
the normal driving condition.

Can this problem be caused by fuel pump, cause the engine is working
on idle (when warm) ok, and when goes over 4000 rpm till 6000 rpm
is working better (but it still makes missfires in engine work) ?


My mehanic and I are clueless :g:

I hate to be the one to say this, but i think there is a huge language barrier problem here :-/

If i'm interpreting what you're saying correctly, it sounds like there is a lot of back pressure when you press the accelerator.

There for, i believe you have a blockage in the air intake system.

Check your throttle body. It may be stuck. Use throttle body cleaner or Deep Creep and an old tooth brush to carefully clean the throttle body and butterfly opening.

Jop, it's been some time since I last realy used english writting ... sorry for that.

Yes, there is lot of back pressure when I press the accelerator, but
the air intake system is clean. As far as I can see/hear is that engine is
getting to much of air without fuel, so I'm suspecting on fuel pump,
that it dosn't generate needed pressure. Strange at it, is that at idle is
working fine and over 4000 rpm is much better then from 1000-4000 but it woud
be logical that in higher rpm's woud be worse cause less fuel is comming
to injectors.

If this is true, then there should be a Check Engine Light (CEL) while the Corona is on and running.
When you jump terminals T and E1 together, with the ignition in the "On" position, the CEL will blink in a series that will tell you what errors have been recorded.
You should have either error code 25, or error code 26, or both.

The error codes will stay on the computer, unless you remove the battery from the car. If that has happened, then use a mechanic's stethoscope to listen to the EFI fuel rails. Listen for fuel flow, and EFI spray.


Also, try replacing the fuel filter first. those should be cheaper than a fuel pump.

Chances are, you may just have clogged injectors. After replacing the fuel filter, run a fuel system cleaner through the gas tank.

When you describe that "it blows into airintake system" or "when I give gas I get this blow into air intake system." are you describing what we term a "backfire" where there is a loud bang?

Is there any chance that you could post some pictures of the engine compartment so we could get an idea of what kind of engine the Carina II has? Heck, post a picture of the Carina, I'd like to see what it looks like!

Thanks,

is it pushing air out the intake or just not sucking any in when cranking?

[oldtoyota]

Yes, I have "back fire" in air intake system, cause when I give gas, engine don't want to rev in higher rpm, but it gives this back fire. On idle works fine (when warm), and when goes over 3500-4000 it runns better but still far away from normal. Belt is o.k - in faze, fuel filter is new - clean, cabels and spark plugs - o.k., engine dosn't consume any water or oil (0,5lit of oil at 10000 km).

Like I said before, NEVER had any single problem with the engine (except with starting the engine at temperatures
bellow 15 C, when never don't want to start with first crank, and allways from seconde time) and this happend
in drive.

Here is the picture of my engine.

does it have a cat converter?
