Hello, my first post - please be gentle



I recently bought a 1993 RX7 FD3S. Very recent rebuild, good compression tests in February (high 7s all around). Mostly stock with some mods which have no effect on the problem described.

The car has no issues when starting from cold, but more often than not hesitates, loses idle rpm and just dies when started from warm. It does start fine, though, but I have to rev it up for quite some time.

Spark plugs were replaced at the rebuild time. My guess is I need a new set of NGK bur7eq/bur9eq?



Thanks,



Jim
