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,

from outside looking engine everything seams o.k., but dose not work !

I want to say that since 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 or after 10-20 km.

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 !

Hello my friend.

Ok, so you have a lack of power?

But the engine sound like normal when idle..

Check these things.

when you get ready to start the car, you will see lots of lights turn on

(key in acc position).

You will notice an amber light that looks like an engine, does that light up?

Once you start the car, does it stay lit ? or does it turn off.

Have you checked the throttle sensors? and the oxgen sensors on the exhaust mainfold?

get your friend to clean all the sensors.

Please explain what you mean BLOW ?

Hello,

No lights on instrument board stay on when engine starts,

that means that engine computer do not give any errors.

The engine makes back fires in intake system (explosions).

First it's very hard to start it. Cold engine (when started)

goes at 1500 rpm (like normaly) but stolls after 2-3 seconds.

After 4-5 starting over it finaly starts, but when I press gas pedal

it's goes till 2000 rpm, but the sound is like that only air is comming

into engine (deep sound), and from time to time explosion in intake

system ocures.

I will try to clean everything I can, and to check out everythink I can.

I just hope that the main computer (located in cabin) it's not went bad.

Any ides what may be the problem ?

Right so the car is miss firing.

I would check your distributor /coils and leads.

One may be faulty

Does the engine sound like it is running on 3 cylinders?

Check resistance on the leads..

what have you replaced so far in services ?

HT leads? distributor?

The engine dosn't sound like it is running on 3 cyl, it's more like

it's out of faze and that it needs 4-5 trys with gas pedale before

it gets over 2000 rpm.

The problem is that I don't have any spare parts for this car

(or the service) cause it's a '91, and shoud be a long time ago

at junk yard but it was running problemless since buyed.

And now I will be forced to give it away regardless it's probably

some minor problem.

[cmia]

Look at the coils/distributor.. and sparkplug leads.

Iam sure they will beyour prblem

[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.

http://autorepair.about.com/library/....htm?once=true&

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

[cmia]

ok

Do me a favour..

Rev the engine to 1k and hold it,

Get your friend to unplug the spark plug leads .... ...

Ie remove number

1 cylinder - listen to the noise

plug number 1 back in

remove number

2 cylinder listen to the noise

plug number 2 back in

do the same for 3 and 4

listen to the engine, and see if it sounds any diffrent, ie struggles to run

Fuel pump or fuel filter could casue similar peoblems.

how have you tested the HT leads ?

[oldtoyota]

I think we have found the problem.

It's fuel pump wich has "done it's work" in last 220.000km

The problem now is that new one costs arround 450 EUR,

and I dont know what can be the alternative, cause it's toomuch

for car with 1000 EUR value. Any sugestions ?

Used one it's hard to find in my aera, so it woud be nice if somebody

know what can be done.

Reparaton of this one or buying new one from diferent manufacture ?

O.k. 8 days of finding the problem at my Carina II 4A-FE

Since now, I have been checkin out allmost everything what was

possibile.

- timing belt is o.k. (number 2 on photo)

- injectors are cleaned, tested and o.k. (no.1)

- fuel pump is o.k - pressure is normal (no. 6)

- fuel filter is new (no.7)

- distributor, cabels and spark plugs new

- throttle position sensore - o.k. (no. 5)

What I have done today is (my luck that I have found it on one old Carina):

- replaced Manifold Pressure Sensor or vacume sensore

(number 3 on photo bellow)

- replaced also sensore (number 4)

With all dose actions, problem stays the same.

I'm starting to think that the problem may cause a broken

wire somewhere cause the problem has accured in one moment

(never before I had a single problem in engine work) and the only

possibility is a broken wire. Also when I unplug MPS and try give throttle

engine work is a little bit beter but still not normal, I have changed that

MPS (Manifold Pressure Sensor (no.3)) but no changes.

p.s. this engine has no air flow meter sensor, it's written in toyota manual

I think insted of that is Manifold Pressure Sensor wich I have changed

but without results.

When done diagnostic i get codes 22 Water Temperature Sensor, 31 Air Flow Meter Signal

and 51 Switch Condition Signal.

Ideas ?

[oldtoyota]

The car is at Toyota authorized service for more then 10 days now, and they are clueless about

what the problem is. I think that the future of this car is very bed :-(

Also I don't think I will be buying Toyotas in the future, specialy when the service is not able to

fix or to only make diagnostic on an old car, what woud be with new one then ?!?!?!

Have you tried a cylinder compression check?

If the intake manifold is being pressurised it might be a burnt out or sticking inlet valve.

A compression check would help to pin point the problem.

Another problem I have come across in the past is one of the lobes wearing off of the exhaust camshaft.(A common fault on old Volvos)

This causes a really loud noise from the inlet manifold when the engine is revved.

A similar problem can also be caused by a blocked catalytic converter.

The way to check this is to disconnect the cat from the exhaust and see if the engine revs freely.

I have been experiencing similar problems with my Toyota Carina II 1990 GLI Executive.

The symptoms sound the same and the mechanic who has looked at it does not have any answers either.

Sometimes car is fine for days, but then when 2 minutes down the road will start being sluggish and uneven it's acceleration. After a little while it goes fine, sometimes not having the problem again for days. Sometimes it cuts out while I'm in the process of taking off, then has trouble starting again, or starts fine!

Other than the suggestions tried by oldtoyota, does anyone have any more ideas? Or did oldtoyota find the fault in the end?

Please feel free to ask for more info!

The problem was in ECU, when I changed the ECU the problem was solved.
