I'm new here but loving the site already, so much information to take in!
To cut a long story short I have always had problems with erratic rev's in my car (Mk 4 astra 1.4) most of the problems were solved when I got my timing belt done a couple of months ago but lately I seem to be having some more problems.
In particular when I first start driving the car either in the mornings or after work the car will chug like crazy in 2nd gear at anything below 3k rpm... and then when I come to a stop and press the clutch in fully the car rev's itself up to around 2.5-3k rpm and then drops back down to normal.
This happens every time I stop the car unless I have been driving for a few minutes and everything is warmed up. Any ideas what it could possibly be? I am going to try (weather permitting) to clean the EGR valve and ICV tomorrow using the guides on the site.. this will be my first attempt at anything like that so hope it goes well! My engine management light has also been on constantly for the past couple of weeks but I havnt noticed that affecting performance in any way.
My plan was to try clean the ICV and EGR tomorrow and check my pretensioners (yes that light is on too ) then bring it to my local dealer to have tech2 turn off the lights and see if they come back on.
Anywho if I don't stop now this will become the life history of my car... any advice?
