Hey whats up guys,
I think i have a ground problem with my 98 z.When open up the editor in my hptuners,the car starts to run rough and throws a crank shaft and camshaft fault..And the other day i went to have the inspection done on the car and when i started it up with the inspection machine plugged into the obd port,the car would barely run.I pretty much had to give it gas to stay running.When i unplugged the machine,the car starts up fine.It failed because the readiness codes were not ready.I plugged in a box into the obd connector to tell me when the readiness codes are ready so i can get the car inspected,and the car was throwing a rear o2 sensor low voltage fault(p0137).The car also throws a pending misfire code on when the car sits and idles after a cold start.I replaced all of the ignition components and it still didnt cure the problem.So,are there any ground points on the car that are known to go bad?I checked the grounds on the front of the trans and under the battery tray and they all look good.Any ideas?Thanks.
