Idle Issue Help Please Options

[justin_getz]

hi,


I have not posted in a while and it seems that the getz has gone worse, it now switches off twice per trip and takes 10 minutes to start.

Its gotten so bad that we dont use teh car anymore. I took the car to hyundai yesterday and they checked the sensors, ran a diagnostics and told us nothign is wrong.

there was no printer attached to the diagnostics machine, so i took some pics.

is there anyhitng wrong here?

So the engine runs normally in service garage :-(. Check and clean MAF sensor on the intake. And do it yourself so you will be absolutely sure it is cleaned. And check if the fuel filter had really been replaced (must look like brand new one).

I'm telling u this because I had some bad experience in the past, when a mechanic said he replaced smth, and then I found out, it hasn't been (and he charged me the 'replaced' part).

Go and have a look yourself. Some mechanics like desperate ppl like u (and me) for exploiting.

Good luck, and hope u find the source of u'r problems soon.


cheers,

The main reason for rough idle, in any fuel injected engine (not just Hyundai), and NO auto computer will reveal or give a trouble code, is DIRTY OR CLOGGED FUEL INJECTORS.

Fuel injectors can get dirty in a split second. From one day to another. Reason is bad fuel (contaminated with water, other fuels or solid particles).

One cheap way to outrule fuel injectors, is to pour a whole bottle of fuel injector cleaner additive to an almost EMPTY tank, then add 10 liters of fuel, no more. then drive your vehicle "hard". That is, revving up you engine a lot, like doing street races.

Try to use up all the fuel in tank, which should be around 1/4th of a tank. Then, when you get home, disconnect the battery for at least one hour. Then reconnect battery and try to start engine.

I am almost sure all your problems will be gone. By disconnecting the battery for a long period (at least one hour), you are indirectly resetting every single parameter and clearing every single trouble code that might have been recorded, including any memory developed and stored by the ECM about driving habits.

Hope this helps.

hi,

So i left the car with hyundai for the last week or so and they drove it around and got it to cut out.

They now tell me that they have tested the fuel pump and it seems to be failing.


The car is out of motor plan and they want R2500 for the pump excl vat and labour, that is a bit much dont u think?


Where can i source this pump from cheaper.

So i gave hyundai the go ahead to install the new fuel pump, they fitted it, then told me everything was fine, i fetched it and the next day my wife is driving home and the car dies. this time it wont start. So we get it towed to hyundai and they drive it around with the monitoring computer attached and nwo they tell me that it is the ECU.

The SM tells me that te car is fine and then all the lines drop and the car dies. Today they are sending the ECU for testing.

i have no fait left in this dealership.

Its sad to hear that you are still having problems. Anyway, sooner or later they will find what is wrong and fix it for good, but remember to claim back (refund) all the expenses done due to wrong diagnosis. For example, the new fuel pump apparently was not at fault and it shouldn't had to be changed, because the problem persists. Also, the towing expenses can be claimed. I don't know how consumer laws work where you live. Around here, you can claim back any and all expenses made due to bad repairs as a result of wrong diagnosis.

Back to your car's problem, it seems there is an intermittent fault that causes the engine to die or run bad (rough idle). This sounds more like a bad contact (corroded or dirty plugs in wiring harnesses) or a loose contact somewhere in a sensor or circuit board. I know this is not much help and if it turns out to be the case, such problems are the most difficult to pinpoint and properly diagnose.

Let us know the outcomes

So i get a call from the dealer yesterday to say the car is fixed.

I ask him what was wrong, i was expecting him to say the ECU was fubared, but instead he says it was the anti-hijack. He says the forman called a few technically inclined friends and they told him to disconnect the antihijack and test the car.

its been a day and 125km and the car hasnt stalled.

i am going to fetch the car this afternoon and will use it alot this weekend. I hope it is the antihijack.

I just want this to end.

So the car has been fine with the new pump and disconected anti hijack and new new fuel pump.

I went to the dealer today to get the old pump refitted and my refund. They call me back to say that the old pump wont switch on, he said the antihijack cutting on and off all the time must of fried it. I went there they connected 2 wires, and said look nothing. I was so upset i just told them to give me my keys and i left.

Then i got home and cooled down a bit, and said that im not going to leave this, their incompetance led to the pump getting fried and they should bare the cost.

what should i do?

hi,

I'm glad you got it fixed. About the pump: not worth it.
