On my 92 Acura Integra, my distributor broke so I replaced it...The new one on it, i believe, is making my tachometer really jumpy. I would drive and it would jump from 4,000 RPM to 5,400 RPM and then back. And this mostly occurs when the engine is cold, but when the engine is warm, it still jumps but not as much. Is this the problem with the timer & the position of the distributor? Also, I'm not sure if my Integra is a 1.7 or 1.8......if I had a 1.7 and used a 1.8 distributor would that make a big difference?

Please help! Email if possible thanks

 

If you have VTEC, you might have the B17A. I'm not sure what years the B17 was used. I think it was discontinued before 92, though. If you do not have VTEC, then you do not have a 1.7. It's a 1.8 if you have no VTEC.

I'm pretty sure the igniter runs the tachometer. Check the wiring in and out of it. Might be something loose, frayed, etc.

 

Did u set the timing when u replaced it? That could be your problem too. I'm pretty sure you have a 1.8 engine.
