hi,

I wish to gather some information regarding these two problems that I have with my in-law very old car (more than 10 yrs and about 200,000km, auto). I would like to send the car for service but it will be good to have some information from the experts here.

1. When I start the engine, it will stall if I do not step on the accelerator. What could be the problem? Actually, this problem has been there for a long time, but did not do anything. Recently, change the car battery, this problem does not go away.

2. When the car is moving, when i step on the accelerator, the power does not come instantly. It is a delay response. The power will come GRADUALLY. Meaning it will slowly increase power at first, like it is dragging something and then after 1-2 seconds, the acceleration will be normal, like the "thing" that it is dragging has been free! I do not have this problem before.

Thanks and Regards

Does it hold rpm...hmm...i will have to check again when i go over this weekend. Will update again.

Hi bro,

1. When the idle does not hold when stationary, that means there is no air going into the combustion chambers thus resulting for the engine to stall.

2. The 3 things that normally control the intake of air going into the engine at idle is the Idle Air Control Valve (IACV), Fast Idle Control Valve (FICV) and your idle screw. Depending on the make of your car, you may/may not have some of these components.

3. Its more than likely that either of these components are old and stuck with sludge. They may need to be cleaned, or replaced. Your workshop should be able to advise you.

4. With regard to your 'power' prob, it can be the fuel filter (clogged, thus starvation of fuel into engine), the distributor and its sub components that control ignition, or spark plugs, plug wires that delivers the arc into the combustion chambers.

5. The car is >10yrs old and is likely that its was not regularly maintained. To refurbish it back to pristine condition may cost you in excess of thousands of dollars.

6. You may want to consider bringing it to a trustworthy workshop, get them swap in some compatible components sourced from scrapyards and be happy driving a car that serves its purpose of transporting you from point to point.

Cheers.

hi, wanna to update everyone regarding the problem.

hi superkoh, I did not have a chance to check the rpm, coz when i have the car to send to workshop, it is already in late afternoon (engine already hot!) and the car acceleration is not as bad as in early-morning-start.

hi ig108, thanks for your advice. As it is already late in the afternoon, I only went to one workshop. After talking about the problem, the mechanic also cannot guarantee everything will be fitted or pin-point the problem. Or I should re-phase, can be fix, but it will take time and will probably cost a lot as the car is old.

So here are the suggestions by the mechanic:

1. The mechanic pointed out that the old car require minimum 97 grade petrol, but we have been pumping 95 since don't-know-when! Advice to change to 97 ASAP.

2. Then, base on the problems, mechanic suggests to change the carburetor coz this is the main "suspect". So we changed, abt S$240.

After changing, on sunday morning, I am the first to start the engine, again, when i start the engine, I need to step on the accelerator to keep the engine going. The problem still there!

Then on the acceleration problem, seem to be OK.

So will ask my in-law to try to finish off the 95 and then refuel with 97 and see if there is improvement.

cheers

driving a carb?

even i encounter your issues occasionally... but its really old so its tempermental...

yes it is a carb. I was surprised when told by the mechanic, all the while it had never crossed my mine that it is a carb. And i thought it is a big thing, but turns out to be about 3-fists-put-together in size.

but one thing for sure, when we bring such an old car to the mechanic, the attitude is "so-old-already-what-can-you-expect"...i was hoping that they can check every component. I guess the true will hurt and unless the mechanic is your friend, it is difficult to find one workshop to troubleshoot all component.

but my guess is its not the carb at fault...

maybe the spark plugs & cables?.. for carb i feel not many mech reli noe what its all about coz its so old skool... haha.. now all ECU ma...


i use 92 fuel anyway since the engine oso cant utilise any better grade .. so y waste $$.


more impt are the steering, wheels n brakes for a car.. for any car be it new or old..

wad cc r u driving?

it is a 1.6.

actually I am (or my in-law) not so concern about petrol consumption coz it is ready a "marketing-car". A one-or-two short trip or no trip per day.

I also suspect it is not the carb problem, anyway, due for another maintenance cycle in 2 mths time. so will ask them to check.

Brake is another problem, need to check in 2mths time, coz got sound. But the real is drum, what to take note for drum?

steering, mine is ok (or seems ok leh), what problem did you encounter?
