[quote=“Onyx Z32,post:15,topic:37217"”] It could be many things. Maybe you replaced the PTU, but maybe there is a short in a wire somewhere and you’re not getting proper voltage under load. Or maybe your ECU is shot, who knows. All I know is that you always have problems, lol. You should really take some money and have someone diagnose your problem. Either stop by Licata’s and talk to Jeff or find a good Z tech on TTNET and drive to them. You need to talk to a Z-Pro and don’t take advice from random people who keep steering you in the wrong direction and don’t know these cars _specifically_. (this is NOT directed at you angry Don! lol) [/quote] i’ll be due for inspection soon…so it’ll be at Licata’s anyway…i guess now is a good time to find out where my problems lie since i’ll have all winter to play around with it soon… --- _[View the full topic](https://forums.speedlife.net/t/tight-plug-gap-low-vacuum/37217)._
