Re: Which is the low pressure ac switch ?
Marc did the conversion to 134 so it has the caps on the high pressure line and the receiver. Possible it could be leaking from the other side of the receiver. Hope it's not the evaporator core .

Re: AC help needed at BG C4 Gathering
Don't know why your local shops won't touch your cars AC. Mine has a slow leak so been having it topped off and they don't mind . In fact they offered to try and find it for me . So this year that's...

Re: code 55 still
You say it was running fine. I know when my FPR went the car just didn't feel the same. It didn't pull as hard . Since it had the original injectors I got new ones from white racing that were flow...

Re: BC Forged Wheels Purchased
It would look better if you ran the Michelin PS2'S. The 335's on the rear really fill out the wheel wells and look better than the 315's in my opinion. Those wheels do look nice on your car. I...

Is that what the whole relay circuit modification is correcting ? Is this what degrades over time causing the no start issue?

Re: Barrett Jackson Oct 22-24 2020
I would not take a ZR1 to Barrett Jackson or Mecum for that matter as these cars just don't bring much at these auctions. The white 91 ZR1 just sold a few minutes ago for $20,000.00 plus a $2000.00...
