my friend has a gsr and we can't figure out why his tach bounces around. he tried changing the entire gauge cluster with another gsr and didn't help. just put in an autometer tach and it does the same thing? thanks for the help.

 

your idle might be messed up.

 

what do you mean the idle might be messed up. it bounces as he is driving. like going through the gears instead of steadily going up it bounces all over the place and so i has no idea when he is about to red line?

 

then check for a

vacuum leak
Leaking EGR valve
Leaking head gasket
Timing belt or pulleys worn
Camshaft lobes worn
Fuel Pump not delivering enough fuel
Or air filter clogged.

If you have touched or messed w/any of these or didn't do the maintenace required on them then that might be the problem.

 

didnt know that could happen.. how often does that happen?

check your plugs and wires
the stuff the other guy mentioned, but start witht he basic stuff first...


do you have any codes?

 

ok, i haven't had a chance to check anything yet. like i said it isn't my car. just a guy i know that works next to my work. how do you check for codes on the integra? i drive a crx so i am not familiar with it. i don't think his check engine light is on tho? is is complaining about with getting his fuel right. says it is running real bad.i don't know, i'll check it out tomorrow and get more details. thanks

 

dang sounds kinda like the problem w/ my frenz prelude that I had a thread here

not many ppl knew what it was (not even the dealer) let me know if you figure anything out..

Many times a bouncing tach is caused by a poor connection at the igniter. It is common for people to replace the igniter without tightening the igniter connectors. I always pinch them with a pair of needle nosed pliers before installation. That is where I would look first. Next I would check all connections between the igniter and tach. Some Honda's with external coils feed the tach from the coil- V6's are notorious for bouncing tachs caused by a bad/failing coil.

 

sorry, but bare with my stupidity....ignitor? what/ where is that at? i don't think he has messed with anything like that. changed the plug wires but thats about it when it comes to the electronics part. says it is running really lean? i have yet to look into it. never get a chance to mess with it while i am at work. thanks for the help.

 

the ignitor or ICM is located in the distributor. Could also be the ignition coil, which is in the distributor too.

Exactly what should the readings be on a good ignitor?

 

I had the same problem with my LS motor. We replaced the entire distributer and the problem went away. I could have just replaced the ignitor but yard had them for like $200 with a lifetime warranty.

is it your battery grounding ? my bro's car his battery was grounding everything and his tach was just bouncing around

 

i had a bouncing tach while driving i thought it was my distributor but it was just a loose ground wire (the one on thermostat) so check that out
