sporadic misfires at 3000 RPM 70 MPH
Hi! Car is mint 33K miles and all great /timing/idle/acceleration..etc etc
car is used lightly every week. however when I drive it on highway at high speed - it intermittently misfires/looses rpm power and recovers after a second or two. drove 100 miles at 70mph /3000 rpm and had it sporadically losing power / rpms and recovering after a second or two at least 15 times. ...car is well maintained/new correct plugs,cables etc etc. all advice is appreciatted
Have you checked the fuse box for corroded terminals? You may also need to have the pulse signals checked for noise on a lab scope, sometimes the pickup coils can be erratic.
