So I have a 2004 gp N/A I decided to change the lim after all the research I've done here I changed with new aluminum and coolant elbows, new upper intake gasket and spark plug plus wires and injector oring, pcv valve torqued everything correctly and changed oil 3 times to make sure clean but after turning on it over heats and smoke comes from front exhaust manifold and idles like crazy when I press the gas it feels like it wants to die out what did I do wrong didn't do it before
