I've looked at the several topic discussing idle problems but I couldn't find anything similar to what I'm going through.

I have a 92 Civic LX and I just installed a 5" Tachometer, I used to have a 3" Tach but replaced it with a bigger one. Now my problem is that now my idle is below 500rpm with the new tach but before (with the 3" tach) my idle was at 900rpm.

I'm thinking about adjusting the idle bolt on the throttle but any other suggestions what the problem might be?

Thanks!

 

sounds like the tach is in v6 or v8 mode

 

Oh cool. Yeah, the tach was in v8 mode. I forgot to cut the wires for the v6/v8. All good now, problem solved.

Thanks!

 

dang rice bowl tachs!

 

LOL! I just don't want to change my cluster. Sorry if you're not a fan of tachs.

 

lol im just messing with you. only thing i hate about oem tachs (well at least 92-95) is that they are so inaccurate at high rpm. so having an aftermarket one isnt bad

 

Oh, I didn't know that.. Good thing I didn't buy that cluster. LOL!
