Gen2 step on accelerator but no throttle

[Akai80]

Hi all

 

i have a Gen2 about 6 years old. Sometimes i encounter a behaviour with my car. When my car stopped at a junction and when i wanted to move off, i stepped on the accelerator the car will vibrate (like those manual cars going to stall) and there's no throttle at all. But when i release the pedal, the car continues to move slowly normally in Drive gear mode.

 

i noticed that when i try to step more on the pedal when moving off or in very slow speed (probably in 1st gear), i will not experience this. This behaviour is getting more frequent. Everytime i need to switch off the engine and switch on again den i can drive off. i just went for my servicing last month where i changed the engine oil and automatic gear oil.

 

anyone knows what might be the cause of this?

 

Thank You

You should take to a workshop and let them diagnose the problem but it might be a loose throttle cable or a dirty throttle body......

Fuel filter or fuel pump.

Also during service u may consider change auto trans fluid.

I think its auto gearbox problem.

[Heartbreakid]

Perhaps it's a dirty throttle or perhaps the electronic servo at throttle flap having some issues.

[Mecontle]

think is the prob with the brand hi five

What's the mileage of your Gen2 and how frequent you change your ATF? I suspect your auto going to up lorry soon.

I didn't think I would come across this same problem that I had many many years ago.

 

I used to have a very old '74 Ford Escort, with a 3-speed automatic transmission.

Same symptoms, at junctions, sometimes it would refuse to move off when I step on the pedal.

Basically it was my gearbox, which was almost at its end of its life.

 

Have you checked your transmission oil level? I vaguely recall I had to keep topping mine up, to keep it going until I finally scrapped the car.

Is your Gen 2 using E throttle. Cos for proton campro negine model - Persona , Saga BLM, its using E throttle meaning that accelerator is electronically controlled instead of cable. Its normal for proton E throttle to feel some delay(1-2 secs) before it responds.

 

Seems like the throttle sensor might be dirty/ faulty? Try checking online with msia proton forum or msia authorised proton workshops.

Hi all

 

thxs for all the advice. My mileage is about 120k. During my last servicing last month, i did changed the gearbox fluid. Hmm is this the same as the auto transmission fluid?

 

as the phenomenon is not so frequent previously, it didn't bother me too much then. Actually i'm planning to give a call to Proton Singapore to seek for advise but usually they will brush me off by saying just bring the car to the workshop. In order to avoid the steep repair charges, how can i get the most out of the Proton so that i can have some clues when i bring my car to my usual workshop.

 

Cheers

I would advise you to get it checked quickly. Whilst may not be frequent now, you dun really want it to fail when you're in the middle of a junction waiting to make a turn and oncoming traffic is headed towards you, and suddenly you can't move out of the way!

 

Happened to me once, scary and dangerous!

Get them to check the gearbox and ATF fluid levels. (You can check the ATF fluid level yourself, should be listed in the manual)

Same thing happened to me on my previous car. The ATF had leaked till it was almost empty as I didn't check the levels. It was a $2.5k repair job. Not funny

Jus a guess. U may wan to have ur alternator chked. I had my manual gen 2 with 190k mileage for 7yrs. Wks before i scrap, experienced wat u mentioned especially cold starts im d mrning...

 

Nt cfmed but u may wanna chk with ur regular mech if ur alternator is wrking fine.

I would suggest you send your car for diagnose first, then most likely can determine whether it is the auto sensor giving you issue. No point playing guessing game now as most car this day can check surface issue with simple diagnose tool.

 

I'm a gen2 owner (A) model still owning and driving it, car mileage as of now is current 160k++

Hi all

 

actually i have brought my car to my regular workshop but the no throttle issue still persist!!! The boss changed my spark plugs and my accelerator pedal (he suspects that the pedal sensor is faulty). He also used his diagnose kit and my car didn't show up any other warnings. Guess i have spent about $500 in total already.

 

should i continue to bring it over to him to check or should i changed to another workshop?

 

Thanks

I had the same problem, press accelerator no move, had to play around with gear then it engage, few weeks later, gear box up lorry..urs survive so long, still beh pai..

Bring ur car to Plentong, JB, it is a Proton Service Centre.Should be much cheaper than doing it at Sg. Google the address.

It is somewhere near Pasir Gudang.
