what's up fellas.. I hav4e a 96 Honda civic si d16y8.. My rpm gauge jumps around like it has a mind of its own sometimes.... What's happening to my baby??? Haha.. Also the beginning of every gear the car put puts or sputters or hesitates like its not getting enough ... But when i cold crank it runs just fine till it warms up them it

Check ICM, a problem with the tach points to an ICM, [igniter] problem, [along with the performance problem]. 94

Jason Hatcher

It was doing it yesterday and hasn't done it since... But what's the easiest way to check the icm

fcm

Pull it and test it, but first, [because it is intermittent check connections to the ICM, unplug terminals clean "crimp" the terminals a little tighter before you plug them back in

Did the performance problem also go away? 94

Jason Hatcher

As for the sputtering... For some reason it went away and the check engine light turned off also

Jason Hatcher

Nope the sputtering is back... I was told to replace my fuel pump... Does this sound about right... Anybody

Have you checked fuel pressure, is it low?
Replacing parts just because someone tells you to is an expensive way to diagnose a problem, low fuel pressure is more likely to effect engine performance at high RPMs not low, [idle] RPMs.
A permanently mounted FPG is not expensive and a very good diagnostic tool for quick reference at any time you have a problem, I have a B&M permanently mounted at my fuel filter.

mine only sputters when i take off so low rpm's.. It doesn't sputters at high rpm's.. And my engine is sounding like it's whining up with my rpm's

you had a cel. retrieve the trouble codes. the on-board diagnostic (obd) system exists for a reason. use it
