How to avoid re-learning after cleaning throttle bottle?
Hi Scotty and guys! Greetings from Israel!
My 2007 Peugeot 407 2.0 petrol started to idle roughly and the area around the throttle bottle`s butterfly was quite dirty with carbon. No maf sensor on these. I cleaned the area gently with carburetor spray, a toothbrush and a cloth, being extra careful not to move or force the butterfly while having it open by turning the ignition key (without starting the engine) and sticking a pipe between the gas pedal and the seat. I did this before on a 2010 similar Peugeot 407 we own, and had no issues after that. However, the 2007 went to safe mode after restarting and wouldn't get out of it, would crawl at 20 km/hour and that was it. I cleared the codes, rode it around, and let it idle at working temperatures for a good while, all this a few times to no avail. I had to tow it to a specialist with the right software to have a bottle throttle relearning procedure done. By the way, the car idles fine now.
Can you think of a way to avoid this in the future?
Do you think it could have worked out better had I sprayed Liqui Moly Intake Cleaner with the engine on, instead of manually cleaning it?
