1990 z24 loses power at 1800 rpm. Replaced fuel injectors,
plugs, wires crank sensor, fuel filter, vacuum lines, ignition
module, and tps plug. Anyone have an idea?
The fuel pressure needs to be measured with a gauge to see if it is dropping at 1800 rpm.
Also take a real close look at the coils. You could have on breaking down under load or it could be split or otherwise damaged.
Thank you Bob I will do so
