Throttle Pulse - Honda Forum / Acura Forum

Ok my brother just instaled a Motorvation throttle body spacer onto his 94 civic with a 1.5 liter engine and now the throttle is pulsing from 600 to 1300 rpm's constanty at idle. We tried taking the spacer off and it didn't fix the problem. Any suggestions or help would be greatly appreciated. Thanks

rest the ECU.

Check the IACV could be dirty.

Why did he put a spacer on?

To be honest with you I'm not even sure he says it mixes the fuel and air better?

Ok so he reset the ECU and it's still doing it. Any other suggestions?

yeah, did you try the IACV? And Vac leaks? Did you connect everything back together after putting the spacer on?

I think he's takin it to his mechanic after work so I don't think he wants to mess with it anymore. But I did do a search on the IACV and that sounds like his problem but I won't see hm today to help hime fix it. Thanks for your help though
