I have a 2001 Lexus ES 300 and each time I start the car the RPMs will dive straight back to 0 and the car will die unless I keep my foot on the gas pedal (foot off pedal = RPMs drop to 0 and car dies). However, once I get up to speed and drive for a while, the RPMs will eventually return to normal and I can take my foot off the pedal without worrying about the RMPs dropping to 0 and having the car stall.
This problem used to happen sporadically but now it happens almost every time I start the car. I’ve taken it to two separate mechanics (both “repaired” the problem but it started to come back after a week of driving, I’ve forgotten what changes they did to it as this happened a while ago – but from now on I will make sure to document what’s being repaired so I can finally get this problem fixed).
Thanks for any input!
