rough idle hard shakes, trouble shooting headache
Hey, my name is maurice from miami I'm new here and in need of some time saving advice.
I have a 91 gt that I bought some time back as a project I'm trying to finish her up but now I have the problem of a rough idle. The smog system has been ripped out and there are no o2 sensors the and brake booster has a leak. Its a bone stock motor with bbk longtubes. Unfortunately the previous owner welded the o2 sensor holes. Is there a way to bypass the o2 sensors, and can the booster vacuum leak cause the rough idle?
