Just got my PCM reflash done from the dealer and now i noticed that when i come to a stop my idle is between 600 to 1200 with the AC on/ off. Also sometimes it would jump to 1500 and just rev between 1300 to 1500. Whats wrong? Is it because of the new programming?

 

yea, its the new programing. as far as i know there is no fix for it yet, just gotta learn to live w/ it

 

that is why i refuse to get it done...heard nothing good about it

 

mine dose the same thing called mitsu, and they said it was the idle control sensor, and i said no it only started happening after that reprogramming

 

they told me our cars are running to lean and we are burning up the the cat. Thats why they are doing it. i had done

 

WTF this sucks man. Do you think i can go back in and undo it?

 

Nope

 

You could try unscrewing the negative battery cable for a couple of minutes and then putting it back on. Wouldn't that reset the ECU and allow for things like idle and spooling time to be adjusted based on how you drive?

 

anyone know how to undo it themselves? if its even possible?

 

not possible w/o gettin a new ecu that the flash wasnt done on.. what the dealer did for me is they cleaned the trottle body and adjusted my idle, which worked a little bit, but i guess over the last month or so i got used to it

 

WTF Im gonna call them up on monday and complain my *** off about this. Oh i dunno if i mentioned before but when i have my ac on and i turn it off the rpm jumps to about 1200 and then goes down to 600. Anyone else got this problem?

 

Mine stays at about 2 when you first start it to warm up the cat, I figured it was pretty normal now since they set the idle higher and hotter so the cat can warm up. But I have the same problem when driving. It jumps around like crazy. Especially with A/C or defrost on.

 

Thats exactly whats going on with my car^.

 

Drive on it a few days. After I got mine done it just acted goofy and I knew that was what caused it and went home and unplugged it to just reset the air intake settings. Then just drove around on it kind of easy shifting at all the recommended shift points and what not. It's a lot more stable now but with the A/C or defrost on it gets a little crazy. Especially if I drive off before it settles down at 1000.

 

Well even after mines warms up, my engine still runs weird when the fan foes on and off( while ac is running). I'll try the un plugging thing hope it works.
