1997 Accord EX V6 w/78K miles. No matter if it's hot or cold, rain or shine, lately and like clockwork, after 10-15 minutes of driving (no matter what the speed) my tach jumps wildly. Very soon after the tach hits 0 RPM and the engine starts to buck and stutter. It remains until the end of the ride but never stalls, and the check engine light does NOT come on (The light does cycle through at startup as it should). The problem resets itself after the car sits for a few hours and then the problem happens again on cue. My question is which electrical/ignition part if any is causing this? The plugs/wires, distributor, fuel filter, PVC valve, O2 sensor, ground wires????? I'd like to try to fix the problem myself, keeping in mind I change the oil and filters and that's my extent of repair knowledge, but not afraid to learn. Thanks in advance, and any help or direction would be great.

 

search, there are many threads about the jumping tach

 

is this just the tach acting crazy or ur car acting crazy.
cause if its just the tach acting crazy u need to cut the 2 lopped wires on the back of it, thats if thats ur having problems with just the tach.

 

No, I wish, first it's the tach THEN the engine starts stuttering. I'm lost at what to do first. I just ordered the Honda Accord repair manual to guide me through replacing things. I just thought if I could narrow it down to XY or Z and not try to replace everything. Thanks.
