1999 Disco 1 with 4.0. I had head gasket issues so I replaced them with new gaskets and ARP studs, I had the heads resurfaced and checked for condition. All went well with the re-install. Now the coolant level in the reservoir blows out when driving. New thermostat, cap and reservoir as well. Pressure testest and all is fine. It does not overheat and runs well for awhile. It now want to stall and not take fuel when depressing the throttle. It idles fine but I have had to limp it home twice at idle now. I don't think these issues are related according to what I have read on this site but I'm only guessing at this time. Any pointers or directions in chich to look? Thanks!!
