Sorry for the bump from a new guy. Having the same issue as the OP of this thread. Hesitation, choppy idle, etc. replaced the plug and wires, double checked the plug gaps, switched the plug and wire on #2 to #6 and still get the P0302 code, flashing SES light. From this thread I am leaning towards the camshaft position synchro, but wanted to be sure. Btw, this car is a Base V6, 3.8l, automatic with over 150,000 miles on it. Trying to get it running right without dumping money into parts left and right if I can help it because we are trying to sell it.
Appreciate the help in advance fellas.
