Random Multiple Misfire, Running out of Solutions
My 01 Blazer was idling really rough, throwing the random misfire code for a couple weeks, I changed all the spark plugs, wires, and cap and rotor, no difference. Then my truck started blowing steam out from the hood, turns out my intake gasket blew. The weird thing is that after it blew, my rough idle and misfire problem went away. Next day I go and get new gaskets, a new thermostat, and a new spider injector. Everything gets installed and now my idle and misfire problems are back, but now only after the car heats up. If I let it sit overnight it starts up faster than ever before and runs fine until it heats up. Then if I go to start it maybe an hour after it's been turned off, it has to crank for about 6 or 7 seconds before it starts. Does anyone have any idea what the problem could be?
