1970-1995 Range Rover Classic
Recently got my 95 LWB back on the road after sitting for about 4 years with a blown head gasket. Since replacing the head gasket (heads machined, new valve seals, all top end gaskets replaced) its begun to have a hard start problem when hot and cold, cranking enough and fluttering the throttle will get it to start eventually. Once running it’ll do fine for a little while (between 5 and 15 minutes) then it’ll lose power and won’t rev over 2000 rpm. Shutting it off and restarting will fix the problem for another 5-15 minutes. It seems to act up more when it’s hot and sunny outside (80+ degrees in Florida) I’ve already replaced the plugs, plug wires, O2 sensors, MAF, fuel pump, fuel pump relay, fuel filter, and have an ignition amplifier on the way. I’ve also run about 5 tanks of 93 octane ethanol free gas through it since getting it running again. Did a quick google search and browse of the forums and couldn’t find anyone having this exact problem if anyone has any ideas help would be much appreciated!
