Help im lost

compression test all cylinders until you find one that is reading fuck all
dont think its bad spark cuz then unburnt fuel would be coming through the exhaust and you'd smell it big time
either way it sounds like big money to fix

Have you checked the motor mounts? My civic rumbled like a V8 when idlebecause of a faulty hidraulic motor mount.

youd hear it
plus a 94 civic would just have regular rubber or whatever mounts, no hydraulic shit

Nigga what city does your bro live in?

Yeh p30 ecu. Took it to a small shop today. Theyre gonna check compression, fuel pressure (dont think thTs it) injectors and vacuum. Hopefuly its anything but compression at this point
