A byproduct of Magneto generation is magnetic frequency interference & another problem it generates radio frequency interference. My question: Is there something really wrong with the tach that would make converting it to negative ground a waste of effort or is the bouncy needle more likely some loose wire or bad ground or evil troll living in the coilsomething that only needs a reasonably minor fix. The general rule of 10 PSI per 1000 rpm is usable for most 11/16/2008 · today i got in my car and as i was driving i look down to notice that my rpm gauge needle was sitting at the bottom bouncing but the speedomoder needle was just plain not working, the temp and gas gauge were fine though. That's not the biggest problem I have. This is usually 20-40 minutes into a trip. Followers 1. B. On my 930, the tach sticks when doing full boost runs somewhere before redline. A vacuum gauge can tell you a lot about an engine's condition, similar to a full leak down test - but in a much easier way. My son and I swapped the old 305 from my Camaro into his Monte Carlo last week. Ask Question 5. My question is related to the first part "my tach is bouncing RMP (500-1000). The instrument cluster is working as it should. Instead, the instrument cluster circuitry controls the gauge needle position based on engine speed messages received from the PCM (powertrain control module). answered Jan 10 '13 at 22:29. My car feels very unsafe and I notice it is worse in the snow. If you started at 800RPM prior rev-ing up, expect it to still be at 800RPM when your foot is off the pedal. Why is my rpm gauge bouncing in the red line level while driving? Why does my Dodge Grand Caravan go into neutral while I'm driving? Why do I feel like I'm going to crash every time I drive? On my way home from work my fuel gauge started up to and was reading empty and sometimes bouncing around. We've got it running pretty good but it seems to have a bit of a miss at idle and the vacuum gauge bounces from 16-20 lbs. That sounds like a misfire. The tachometer jumps around when I'm holding a stable throttle, i. A. trucks. 6/13/2012 · Hi All, Im more of a lurker but Ive been reading since I got my Y-reg Octy back in 2008 and Ive appreciated the help Ive had either asking direct questions or just reading other peoples experiences. https://www. I'm starting to worry because the Cleveland winter is approaching. 13. 9, V6 gauge system
