Mazda Miata Fuel pressure Problem
Problems: low power when driving.
I have changed the GN10047 ignition coil and installed new NGK spark plugs. But still have same problems. When I drive it and turn on the A/C the power reduces even more. Can you answer my problems with my 1991 Miata MX5?

scan for codes and check fuel pressure first. then check vacuum at idle if 15" or below suspect clogged converter
