So HC limit is 180 and the guy tested it twice
first test: high speed rpm 2397 HC reading was 157. Low speed rpm 645 HC reading 241
Test 2. High speed rpm 2574. HC reading 173. Low speed rpm 657. HC reading 303
What the fuck gives here? It passed back in february, but fails after I fixed all the problems. No codes, no smoke or bad smell out of the exhaust, plugs, wires, distributor cap and rotor were put on new right before the headgasket let go. Do I need plugs again? Would messing with the dist timing help?
