hi all, harold again, we checked all systems as to the tips you all sent in, such as secondary port vacuum system, and it holds 12hg. going under the plenum and also back to the pump.fuel pumps are new as are o2 sensors.car still shows a code 61, and wont run over 3000 rpm.if engine passes the vacuum pump test ,can i assume everything is ok under the plenum,or do i need to take the plenum off and check furthur?also, is there a way to check the ecu. i really appreaciate your input. thanks again Harold
