283538 2004-10-22 22:03:00 If it is an engine related problem then I would say you need to check and/or replace the basics.

1. is the air filter choked up with 10 years of leaves and dust?

2. whip a couple of spark plugs out and see what sort of condition they are in.

3. as has already been mentioned, herl a new fuel filter in it.

also check all the rubber vacum and fuel lines. A small hole in one of these could create a stalling or lagging type problem.

283539 2004-10-22 22:08:00 On second thoughts after reading it again I think it is definitly a transmission issue, take it to a decent workshop shop and get the auto trans flushed out(cost about $200). this will replace all the old tranny oil which is something that cant be done by releasing the sump bung. This has probably never been done since new and will hopefully make a huge difference and fix the problem(get them to check the belts to) miknz (3731)

True, you have to replace the sump bung and replace "the old tranny oil" through the filler. After the flushing process, it may even be worth using "new tranny oil" ;)

283541 2004-10-23 02:18:00 dunno what it is. we did a oil change and a oil filter change 2 day ago .. so hope for the best. yeah the auto gears needs a clean. know that its a need everything few yrs or so ... never got around doing that.

Billy, umm..the car does not stall or cough when the jerk comes on. the startup is fine. well maybe it stalls when there is no power when the accelerator is pressed but give it 2sec and then the acceslerator works again ..

the problems before, my old post. startup is fine again but when its cold it occasionaly loses the ignition - yeah it coughs and stalls, the 2nd ignition startup always work thou. never been scared whether i would be stranded or so .. this is the carb issue i think. somewhat related also i last time i said that it takes some time for it to wind up before the accelerator gets gas (but never losess ignition) - carb issue i think "stick" pointed me to last time. how i figured a work around is that take foot off the gas, then back on, the gas comes on more instant.

ignition is always quick, if the car loses it in the cold it is always after ignition has been received so i doubt spark plugs? yeah could be a engine or transmission ..
at most a niggling thing but annoying.

283542 2004-10-23 02:22:00 this lady's car does not have the revs indicator. only the speedometer.
umm.. when the jerk sound comes on or with my other issue the barb issue. when the gas is pressed i don't think the revs go up. that is if i am correct, as i say, the car has no rev indicator but you can hear it .. just no rev sound .. like i said press gas, no power .. the more gas i pressed i think the jerk goes louder, wait a bit and it goes away, kinda like a instant reboot really :D

this sounds like pointing to a engine issue?

283543 2004-10-23 02:28:00 yeah so the jerk issue. it does not cough or stall, when it jerks, the gas pedal gets no power, speed or rev. jerk may last 2 sec or so .. then its fine ... power, speed and revs return like magic. startup is fine ... nothing there.

before i think its the electronic carb.
that is sometime after ignition it loses it coughing, this happens about 3 sec after ignition. if i pressed the gas while its in P gear, it can be countered... generally when its a cold day.

the other is carb too related. startup is fine. then at the start if u were to climb a bit sloped up, there is no power. it won't lose ignition but its very very slow then after 10sec or so gas comes on and it works again. i have tried that foot off and back on returns power more instantly..

but yeah if gas without rev sound .. it points to the engine.

283544 2004-10-23 05:02:00 OK . . . . . . . . . . .

It is a bitsa of a description, but in the absence of direct contact with the vehicle I'm 95% sure you have an engine problem . Whether it is a carburettor issue (i . e . no fuel or interrupted fuel flow) or an ignition fault (weak spark, shot spark plugs or stuffed distributor leads) is hard to say .

However, most cars have an accelerator pump that squirts a burst of fuel into the carby for rapid acceleration so that could be faulty too . I guess I wouldn't be far wrong in assuming that this vehicle doesn't go in for regular service, so maybe it just needs some TLC . Is there some special reason why you don't want to have it serviced by professionals?

Even Home Tune would be better than nothing .

Cheers

283545 2004-10-23 06:36:00 Hi,

Umm.. well its not my car. The owner basically asserted the car gets a warrant every now and then .. so she puts up with it. As far as she can see its legal, its certified, it operates, if we moan then we can get our own vehicle (so, she says). So, yeah ..

This jerk issue is like once a week or even less than that. So not a biggie.
The cold engine thing well, its warm now. Umm.. I should about a fuel filter change? And maybe a lower viscosity engine oil swap?

We are using Penzoil 20-40W or something like that ..
Spark plugs had been replaced before, engine oil and air filter, yeah .. Yeah a engine issue likely..
