I bought a 1990 crx si with a dohc zc swap. It’s been my daily for about 5 months now with no problems I couldn’t solve right away, until a week ago it died in traffic, the next day it started and I drove it home it died once on the way but started again. Once home I noticed there is no dashpot on my TB, one of the hoses is plugged with a screw and the rest are jus open. Basically I need to know if The dashpot is necessary or if I could just plug the hoses for now as it’s my daily driver?

 

You are fine without the dashpot. It is only used to crack the throttle plate open during starting to help start the car.

 

Symptom sounds like when my main relay started to get flaky, in case you haven't checked that yet.

 

I plugged the open vacuum lines and replaced the idle air valve, it runs much better now, but lacks power and sometimes cuts for a split second when accelerating. I’m going to change the throttle control sensor because a buddy from work had the same problem supposedly.
