Hi Tom and Kevin

Your car has a distributor, so I would use the same calculation 8msx4 =48 then 60000/48
-1250 cam rpm x2 =2500crank rpm

Now if you had dis and a crank sensor and used the duration of one reluctor tooth x
number of teeth, then 60000 divided by that number you should get the rpm of the
crank

Kevin when I asked about the tps I wanted to know at what position the throttle was
open at that capture, as in where you just opening so as to have max air intake or just
snapped close as to have full fuel gulp.

I  was not suggesting the tps as a fault.
