Following some running problems i have been experiencing i believe i may have an air leak on the intake somewhwere. How can i detact where this may be. Is there a simple test i can do?
im running ford pinto efi injection standard set up.

Two methods --

(1) Use a stethoscope (OK a bit of rubber tube) to search and locateor a whistle type noise.

(2) Use a carb cleaner aerosol to search for a leak ----- engine note will change. --- BUT be verty careful obvious fire risk.

sorry to sound confused but how do i go about this. Do i just spray around the manifold and what do i expect to be able to see if anything.

Spray around any suspect joints , engine revs will increase if you squirt onto an area with a leak.
