Hello, my name is rick and I am new to the ZR-1 LT5 world. Let me just say i was a little wairy when i purchased my ZR1 back in march but after the first drive i was hooked and do not miss my 996 at all, this thing just rocks !! http://zr1.net/forum/images/smilies/eusa_dance.gif

Anyways, I have put a little over 2K miles with no issues but just yesterday my Z seems to be feeling a little sick. It sat for about a week and when i started it i noticed a fluctuating idle that looks like its about to quit but the car saves it, sometimes it does stall but i can start it right back with no issues. heres the list of codes i pulled.......

12
13: Left oxygen sensor open
14: coolant sensor high temp
21: throttle position sensor high TPS
22: throttle position sensor low TPS
23: manifold air temperature MAT temp low
41: cylinder select error
42: electronic spark timing EST system error
43: Electronic spark control ESC system error
34: mass air flow sensor low MAP
33: mass air flow sensor high MAP
32: EGR system failure ???
31: Cam sensor missing or too many pulses
12

As i said before the only thing differently was it sat for a little longer than usual and HAD to put some of that cheap "Westar" gas instead of SHELL. Also when i purchased the car it came with the secondary port throttle vacuum unplugled and the car refused to go past 140. I have plugged it in since but have not done another fast run so idk.

Any advise fellas??
