Installed new Bosch camshaft and crankshaft position sensor‘s. Had to order a new camshaft position sensor from Amazon since rock auto sent me the wrong part when I had ordered one as a spare several months ago and I didn’t realize it until going to replace it last week. Trying to figure out a hard starting issue. It seems to happen mostly when the engine is warm like a vapor lock but I haven’t found any posts relating to that here. We’ve put on over 500 miles so far this summer but the hard starting issue makes us nervous.
