its been long time this idle problem make me crazy..

how you say..Intermittent..

I have changed nearly all sensors CTS, Lambda,Throttle poten.,Thermostat, camshaft,crankshaft etc.

Also ICV changed..

cleaned breathers and all necessary stuff many times..

De-cat, exhaust system completely changed..

Except MAF and air temperature sensor..

Tried carbon clean also..All help..Car is much much better..

But problem is from time to time when the engine reach normal temperature 92-93 and I stop at the traffic

lights I feel engine is shaky, the RPM needle dont move but I feel engine tremble different than normal..No EML

lights no error codes..

if you open the bonnet you can see engine is working differently..But no cough no misfire..

After it heats up totaly its lost (20-25 minutes of driving) ...

This is more visible in summer now happens very rarely but still disturbing me..

Any ideas welcome..

Have you tried blanking off the EGR? if you have one that is.

[cem_devecioglu]

Yep..I blanked the EGR..forgot to say ..

Whats left MAF, fuel pump, fuel relay...And trial error is expensive..

as its intermittent nobody could find it

Could there be any water or dirt in the fuel?

From how I read your post sounds asthough it is missing, have you done you spark plugs and leads?
Before I renewed my plugs and leads I had aslight misfire that hardly showed on the rev Counter...
Hope this helps

Thanks Loo-Knee..

I also changed DIS and other stuff.. is it possible to have a new faulty DIS

[Darth Loo-knee]

Did you change your leads when you changed your DIS Pack?

Did you have or do you have oil in your plug wells? This can cause misfires..

If you did have maybe your Leads are damaged and need changing.....

[cem_devecioglu]

yep..DIS and spark plugs and also cables changed 6 months ago..

[Darth Loo-knee]

And there is no oil in the spark plug wells now? have you check this lately?

[cem_devecioglu]

yep..when I buy the car there was oil ..But gaskets changed and all area cleaned 3 years ago.

nearly 1 month ago I tried compression test..We checked also plug wells .And compressions were OK also..

[cem_devecioglu]

may be it leaks from the EGR blockage..But in that case it must be visible I think..

[cem_devecioglu]

seems there will be no solution until I change whats left  :-/

Mine also has a slight irregularity in idle speed - very slight, not noticable on the rev counter.  I have tried cleaning the ICV but made little difference.  Just live with it now.

change much more and you'll have a new car
