To date the RCM, cam sensor, and crankshaft sensor has been replaced. I took everyone's suggestion and replaced sensors with Bosch. Still intermittent start and now backfires badly. Is it possible for a clogged fuel filter to cause this new issue? Does anyone have any other suggestions for required repairs?

I want to thank everyone on this forum for their inputs and suggestions. You all have been a big help. I love this car and just want to get it back on the road.
