Car loses power when hot runs well when cold for about ten minutes, replaced coil and modulator, leads and d- cap ok, low power spark between leads before replacements of coil and modulator after replacement alternating high spark between leads. Symptoms of hunting. Drive well at 4000rpm for about ten minutes then grunts like a pig.
