Hi everyone!
I recently bought an 205 gti and it has a big problem.
The car is a rocket btw , great power , engine starts with no problems, but the car is having a problem with idling and stalling.
Description: When i start the car it goes great before it drops the rpm from 1500 to
1100 (worm up time). The idle speed on my car hunts from 1100 to 500 or 600 rpm and stalls when i stop the car or not pushing the throttle. It gets worse when i put on lights or any electrical thing. Funny thing is that the battery is full , no light intensity changing when hunts rpm. I did this : changed oil and filter (10-40 oil), air filter , fuel injection totally cleaned , opened the air sensor and cleaned out the graphite track with alcohol (there was two lines from needle that left on the track) cleaned cylinder where the oil is filling , metal net ball (or something) in the cap. No results. I saw one screw that is worn out (from a lot of adjustments i think.) on throttle body(not adjustable). I even adjusted the idle speed with air bypass screw on air flow sensor and some gold colored big screw on throttle body . Also adjusted the bosch switch parallel to throttle to click when throttle changes (tested with ohm meter ok.)Any help will be great. Thanks.
