I've search and read alot of related threads, but nothing thats ultra specific to my problem.
I Have a 95' gts-t, and its idle isnt so smooth. Much of the time whilst idling at traffic lights the revs will jump up and down, as if someone is tapping the accelerater (goes from 650rpm to about 900, then back and forth).
Then, I reset the ecu on the weekend to see if it would correct itself, but it didnt. Not only that, but now the car has absolutely no boost! turbo spools, boost guage registers, but theres no boost whatsoever!!
So, Idle fluctuates, & the car goes absolutely nowhere when you put your foot in!
Well today I thought I would run ecu diagnostics to see if could shed any light on this problem. I got error code 13: Coolent temperature circuit. My question is: What does this mean? That the ecu is compensating for the error by rooting around with engine timing or something? I'm a bit lost, as I'm not a huge car person. I'm on the verge of taking it to be looked at. Any input would be greatly appreciated.
Cheers!
