Problem Hard starts when cold, when starts idles nicely and drive well until warm. Even when warm it idles well. When warm and driving it starts to misfire and loose power, ultimately becomes unresponsive to accelerator pedal. Mechanic suggested changing of timing chain, but surely if it was the timing chain it would not idle well when stationary? help

Ryu

This sounds like a potential manifold issue, now I will paraphrase it back to you.
When running at normal operating temperature it starts to misfire
Can you perform something for me please
With the car parked in neutral running at Normal operating temperature can you wait for the misfire then raise the idle speed and tell me if this goes away
 
Let me know

Hi Darren,

Wish you answered last week!

Since I posted the question the car died. I took it in for a tune and it got worse, thats when I posted the query. I took it back and they said that the timing guide was cracked, which was strange as it wasnt running so bad when I initially took it in. The mechanic told me i could drive on it but it would be noisey. I decided it was too noisy to drive and when driving it in to get fixed it threw the chain, missed a cog and died, when they opened her up they discovered she and dropped a cylinder, …not worth fixing. Now I am without a car and have I have lost alot of trust in mechanics! Think I will stick with Honda! Thanks anyway mate.

Ryu,
 
I’m really sorry to hear of your experience but was not aware of a noisy timing chain with your first e-mail.
Hope you get back on the horse soon….

Problem Starter motor is sticking and only starts with a tap of a hammer first. Mechanic has charged $325 for overhaul ( no parts listed) is this a reasonable price?

Hi Andy,
 
Don’t get it overhauled its best to get a new starter it will come with warranty and last longer, shop around for a price

Problem I have taken my car in for its 105,00km logbook service, But the “Service warning” still comes up on the display when I start the car, I originally figured it would go away by itself, But as you can see I’m almost at 107,000 kms and it is still there. Did my service mechanic not do something? Any ideas or help would be appreciated. Thanks.

Hi Evan,
 
Correct me if I’m wrong but in your owners manual it will explain how to remove that warning service light.

You really need to put more effort into your problem, are you running this at low fuel sometimes ?

Problem lately, when driving, occasionally, on depressing the clutch a very loud screaming type noise occurs. Any thoughts?

Hi Dave,
 
It sounds like the trust race, its wearing into the pressure plate diaphragm spring, the bad news is you may be looking at a new clutch replacement.
Try not to hold in the clutch at lights, this way you will or hopefully prolong the life of the clutch.
This was my fathers lesson to me

Problem When starting my car a belt is squealing and then it will quit. When I accelerate after stopping or slowing down it squeals again. Please give me an idea what belt would be making this noise. I know there are 3 belts in this car.
Second e-mail
When starting the car or accelerating after stopping or slowing down one of the belts is sqealing and making noise. It quits after awhile or until you have stopped and accelerated. Please advise which belt could be making this noise. Thank-You
Third E-mail
When starting the car or accelerating after slowing down or stopping one of the belts is squealing and making noise. It will quit after a few minutes after starting it or not accelerating.
Forth E-mail
One of the belts squeals when starting the car and accelerating after slowing down or stopping. Please advise which belt it could be.

Answer
Ruby,

It sounds like the alternator belt if you press on the belt (WITH THE ENGINE AND IGNITION OFF) you may feel a loose belt but check to see if its cracked inside.
If so replace the belt.

You sent 4 e-mails I got the point on your first e-mail

Problem When I start car in the morning it seems it is not running on all cylinders but if you put your foot on the accelorator and rev to 1200rpms it starts to run normal if you leave your foot their for about 4min it then comes good I have changed plugs,leads,airfilter and 6mounths ago fuel filter also a year ago I had a new dissy and a new fuel pressure regulator installed can you help me as Im and old age pensioner and it starting to get very costly at the mechinics they all say diffrent things to me. 

Hi there,
 
The thing that comes to mind is the injectors, or the cold start injectors if applicable, have you ever had the injectors serviced this means taken out and ultasonic cleaned and tested, now before you do this ring Ford and ask them if there is a quick test on the analyser to check if the cold start injectors are holding residual pressure over night and the TPS is not too dirty to effect the air flow sensor.
 
I’m sorry as this next step may prove to be expensive or try to find an EFI specialist that can tell you the answer before spending your money
 
All the best
 
Darren

Darren Thankyou for replying so quick I was wondering if I got a rail flush would that help I had one 6 months ago then the leads packed in around months ago and I had to drive 270km to get home would that have clogged the injectors as it started to miss every now and again until now where it does it every morning the rail flush is $100 as I live in the bush.
thankyou again Gary

Gary
From my experience its the injector that needs to be cleaned now many years ago Toyota had the best additive on the market but I’m not sure about now but my point is give your car a nice glass of wine (Fuel injection additive) if you go to toyota it must be Toyota injection additive not an after market additive that they are selling on the side.
Now Gary if you come accross a good EFI specialist up there in the nice worm Queenland please let my readers know.
 
In conclusion if you try an additive it might help but if you get the injectors cleaned and tested this should show you evidence of a leaking injector

Message Hi
I would like to know if you have the information on how to reset the radio security code after putting in a new battery. The radio is a Fujitsu Ten
If you can help it would be greatly appreciated.

The car is a 1992 Toyota Camry it has a Fujitsu Ten radio in it.
Thank you
Rose 

Hi Rose
 
Try 1234 or ring Toyota and they hopefully might tell you the code if you can prove ownership

Message Hey,
I have a Daewoo Nubira 1998 Sedan.
Recently I just blew something to do with the timing belt.
I was just wondering,
Howwould you know if I have bent the pistens??
Is there anywhere to look to see if I have?
Because I dont want to spend money replacing the timing belt then realising the whole engine is damaged.
Please help !!
Amy,
 
Not looking good without vital information i.e. Type and size of engine, from the research it is pointing towards an expensive repair
