Possible vaccum leak?
I am missing a few sensors like the coolant temp (to the dash), air charge sensor, and o2 sensors. I plugged the EGR, and charcoal vent solenoid
My question is, will the car run without any of the above mentioned sensors, and if so, does my problem sound like a vacuum leak? I don't know if it's because of a leak, missing sensors, no PCM tune, or a combo of the three.
Any help will be greatly appreciated. Thanks in advance guys
