SOURCE: low idling on daihatsu charade 83 model

My first thouhts are your ignition is still your problem, but upu haven't made it clear if the problem exists only when the engine is cold.

On the Charde you must push the pedal down before pulling the choke lever for the choke and fast idle linkages to engage... then start the engine.

The idle circuit consists of an emulsion tube and a solenoid. The solenoid is on the back of the carby and has a green wire running to it. If there isn't 12 volts on this at startup you wont be able to get the engine to idle without pedal assistance.

The carburettor also has an acceleration plunger that squirts a shot of fuel into the engine when trying to increase speed. This has a concetrina boot that can leak. It is situated on to op the carby.

The vacuum hoses need to connected correctly, especially one of the distributor hoses. That one must be connected to AD port on the carby. The following diagram is one of my modified layouts, but should work satifactorily. It is configured so that you can set the ignition timing a little more advanced than factory. When you set the timing make sure both hoses to the dizzy are removed and blocked. You adjust the dizzy position until the dimple on the flywheel lines up with the notch in the timing plate above.

Diagram here

For a test try blocking the hose coming from the oil cap to the bottom of the carby. The cap is also a PCV valve and if it's not clean it can allow excess air into the engine at idle.

My feeling is your points gap is not correct. It should be about the thickness of a hacksaw blade when open. The rubbing block on the points is notorious for rapid wear if hi temp grease hasn't been applied to the rotor lobes. A small gap will cause arcing under load and not provided sufficient dwell time for the coil to charge, resulting in a weak spark, missing, over fueling and lack of acceleration.

I also recommend you replace the plugs with Bosch Super 4's. They will last you a very long time and tend to be very forgiving with older worn engines.

SOURCE: 2004 Kia Optima no start after timing belt, crank, cam sensor replacement

did you use aftermarket crank sensor? if so that might be your problem. dealer has several different ones, by providing vin number, but there is only one after market for all optimas 01-05. try to connect thick pink wire and thick orange wire together on the ignition failure sensor. you might have the same problem as me. good luck.

My 91 honda accord is very slow at take off, no smoke,new plugs and wires and timing belt


Questions:
Is it a carburetor or fuel injected model?
Did the slow take off occur before or after you changed the plugs, wires, and timing belt?

If it started after plugs, wires, and timing belt, I tend to believe the timing relationship between the cam and crank has changed (cam and crank are not timed together properly, off by a tooth or two). Unfortunately you will need to partly tear into it again to verify the timing marks used when the timing belt is changed are perfectly aligned.

Starts then stalls in idle


if the car will crank and run clean the throttle flap if it will not crank and run then you need to check the timing belt

Engine stalls at idle. hard starting sometimes.can run absolutely perfect for a day or two.when engine stalls tach goes completely dead right now. cleaned out inside distributor with Wd40, thought it might...


stalls can be cause by at least 50reasons (and more for parts bad)
the #1 reason from 1920 to now, never doing tuneups.
ever read the operators guide? on tuneups? by mileage?
bingo
http://justgivemethedamnmanual.com/honda/honda-accord-owners-manuals/


bar none. !
ill list (not a guess) the top three not tune up missed.
1: egr leaks. clean it, but is in the service sched for 50k on most cars made.
2: timing belt slipped.
3: isc sticking ,clean it.

the 50 ways are all under misfire, misfire causes too low RPM at idle
and has 50 failure paths. I can post the link, to the ways.
but will not.

Engine oil is dripping from the timing belt side of my 2000 accord after idling for about 5 minutes. Happened after cleaning the throttle body. Any help, ty


Cleaning your throttle body is irrelevent to the oil leak behind the timing cover. There are 5 seals that can leak behind the 2000 accord timing cover, the oil pump, crank seal, cam seal, and the 2 balancer seals. Most of the time its the front balancer seal that has popped out and will need to be replace and have and retaining kit install. Its actually very common on that engine. I highly recommend taking it to a professional to get repaired because timing the 2 balancer gears with the cam and crank is very tricky even for the mechanically inclined. Since the timing belt and the balancer belt has to come off and is probably soaked in oil, I recommend replacing those as well.

I have a 98 dodge stratus. timing belt broke, was replaced. the engine runs perfect at RPMs higher than idle, but at idle whole engine and car shake. . . . why???


This car has a very possible chance of having either a slightly bent valve, causing the loping idle, or the belt was installed a tooth off on the timing, it's one of the two.easiest way to deduce this would be to recheck the timing belt marks, to certify they're correct, then to do a simple compression check, get back to me with any questions, I'M HERE TO HELP!!!

Engine idles rough, misses at 2500-3000 rpm's


i would first check the timing and if that does not fit i would take the cover back off and look at the belt for a bad or missing tooth

Wont idle


put the crank at TDC and the cam gear and TDC slip the belt on adjust the tensioner and then rotate the engine two times make sure the timing marks are still lined up then put it back together and try it if you have the timing off it wont idle right and if could also be the throttle positioning sensor
