I really doubt the car is the problem, if it runs poorly at wide open throttle the carb is not the problem, check the fuel pressure 1st, it should be around 5-7 PSI, if that is ok then you may have a problem in the ignition system.

SOURCE: tune up

At 60,000 you should have all the major things done if you haven't already:
oil change(every 3000)
air filter change(every 15,000)
coolant flush(every 30,000)
spark plugs and wires(every 30,000)
transmission fluid & filter change(every 30,000)
brakes (as needed)
PCV valve (every 20,000)

You can wait until about 75000 miles to do your timing belt.

Hope this helps

If we are talking the three cylinder CB23 engine the mixture screw is hard to get to and has an anti tamper shroud to stop prying fingers.

The Aisan carby is pretty reliable and problems with them on these engines is usually due to improper vacuum hose connections, or improperly adjusted idle, fast idle and deceleration screws.

A/F ratio is around the standard 14.7, but being a carby you will not get consistent mixtures because the jets sizes are fixed . On an EFI engine you can control the fuel flow, but not so with jets.

If you do decide to give your carby a birthday make sure you only buy the Daihatsu genuine, because the after market units have issues with quality. The minor rebuild kit part No 0421287704000 and the major overhaul kit with plunger, needles, gaskets, clips, etc is part No 0421187729000.

If it was me I'd be concentrating on the hoses, the PCV valve, contact points in the dizzy and better spark plugs first. If you want much better idling and a bit better pull get an electronic dizzy and coil from a G200 series Charade.

It may not suit your engine expecially if the engine is a different capacity and in this case the carby jets need to be change or tuned to give the right combustion fuel mixture..

My 2.4 petrol 2001 santa fe is losing power on hills and is gradually getting worse. what could be wrong?


I would guess transmission or fuel pump. The question is when it loses power does it **** or like has a muffled backfire, if it does I would go with the fuel pump, may even need a tune up. I would tune it up first as that is the least expensive and go from there. Hope this helped tim

Have a 2000 Plymouth neon (4 cyl, 2.0) with loss of power and backfire , car has just been tuned up (plugs, wires, throttle body cleaned, air filter, oil change). Just changed the ignition coil today power...


Did this backfiring start after the tune-up? If yes, check firing order of plug wires. Also , if you paid someone to do this, have you consulted with them regarding the way the vehicle is running?

Hesitation or stumble during acceleration


take your car for a tune up
if they are carburetor type motors you may need your carbie cleaned and a tune up
if you clean it your self with carbie cleaner it may increase in idle speed this is nothing to worries about it is a simple adjustment
with a carburetor type motor they tend to idle higher when their cold this is the automatic choke kicking in and normally it should happen till the car is a bit warmer and the accelerator has been depresses
although a car should idle at 800 rpm my paddok car dose when it is cold it idles at 1200rpm i like it this way as the car warms up quicker as i will not drive a car while it is cold
hope this helps

1. 02 sensor
2. clean the throttle body thoroughly by decarbonizing it as well as cleaning the IAC and TPS.
