With my gearbox woes and whatnot, while I had the firewall covers off, and prompted by another thread, I took my ECU out and resoldered/reflowed the solder joints between the PCB and the connector terminals.
Now I've warmed the car up and am trying the 'restart the the car and not touching anything and let ECU self learn it's basic settings'..... For quite probably the first time the car is actually changing revs and seems to be doing something....
My question is how long is this supposed to take before I decide it's actually an unstable idle bouncing between 900 and 1500 rpm randomly? Does it give you a clue as to when it might be mostly happy??
Ooo idle getting down to 800ish on occasion now.. then back to 1200.... And down, and up......
