redtop sr20 issue

[Lemons92]

Hey guys i got a s14 with a sr20 in it. Im having a issue to where the car is fluttering and backfiring at idle and normal driving which isnt normal of course. It sounds like maybe a vacuum line maybe a fuel injector or timing issue and i havent been able to figure it out. I just did all the plugs and fluids. The issue started after i did a pull and i immediately went home and let the car sit cause i didn't know what was wrong. Any advice would be awesome thank you

U have a blown coupler or vacuum leak... get a pressure tester and pressurize the system or get some starter fluid and start spraying every vac hose and every coupler to see if the idle revs up.

Yeah my money is on Vacuum leak to start. Could also be the ground for the coil packs. Good luck!
