Engine Slow Response During Acceleration

[chairoger]

The ECU is telling you it wanna kaput.

Three18, are u sure u're using GT1 to check? It is supposed to be a real computer one (usually laptop thing), not hand held one. The hand held one is usually generic equipment and do not give detail error of UDM. I sudah kena kencing before...

To share, sorry kalau panjang sikit. mau tolong saja

Used to suffer like yours (sama symptom):-

Initially, i changed my fuel regulator - did not solve my problem. Then change fuel filter - problem dissappeared.

Then, engine always died when restarted again, especially at traffic light, engine died when pressing the accelerator and no power at all (itu RPM did not want to climb above 2,500). Thought MAF sensor, but scared of making expensive error, decided to investigate

I used to preservere several months before I could get my time to diagnose with GT1 and woila, my problems were only 3; camshaft sensors error (change camshaft sensors), thermostat error (change thermostat) and solenoid for electric valve for secondary air error (sudah order from Germany belum sampai). Since the camshaft sensors were changed, my problem solved. Its the darn camshaft sensors (mech said ini biasa kalau old sensors punya model). Baru punya, nampak ada lain sikit, ada muscle and hopefully last longer.

Lagi satu usually oil pump components. so many and usually GT1 did not pick up. so good luck in searching and hunting the problems.

when the last time you change gearbox oil??

Actually, I can't remember, but am sure its ok as my mechanic advises me on when to change (By looking at my mileage).

G'Day Sangkuriang,

Thanks for sharing, very detail indeed. Really appreciate it. I haven't run it through a GT1 yet. Where did you do yours (hope its in KL)? My regular mech don't hv that, he just got the handheld unit.

Wonder if the Segambut workshop have it... M1 if am not mistaken...

Better get a mech who has the GT1 unit. How can a doctor diagnose an illness without any proper tools?

I had the same problem a week ago and changing the cam shaft sensor also solved mine. I also thought it was the MAF..

Three 18,

Biasa la, I did all the diagnostics and change the things at M Speed, sama itu Kenny. They do have GT1 and I also updated my software. For simple things, I just go to my normal workshop in Cheras.

Aramis, good to know you solved ur prob oso.
