I replaced the original about 7 years and alot of miles ago.Now it sounds like a jump timing but the codes (number 8 states it is the CYL and TPS sensors.I performed the required OHMS test and it showed no reference to ground,and per the manual the entire distrib.must be replaced.My queston is would a aftermarket cost wise be ok as oppposed to a factory replacement.only other choice is what a 17 year old one from a wrecking yard which in the NW is hard to find

 

check out distributorking.com.........approx $150............lifetime warranty?......good luck
