Hey everyone, so i found out the other day that my oil pressure sending unit was leaking so i fixed that. That includes disconnected a lot of lines, plugs, and sensors as well as the intake manifold. I stuffed rags into the ports and made sure everything was reconnected. The car ran fine for most of today. However, on the way home the car started to shake and shutter in 6th gear around 1500 rpm. I noticed my battery gauge was at like 7 or 8 volts. It immediately went up though when i shifted to 5th. Im assuming this is the alternator. I took the car to the market after getting home and it just died. The car wouldn't start. I kept trying and it finally started. It was almost as if the clutch wasn't grabbing when I pushed the pedal in to start it. Thoughts? Also when I got home i put it on jacks and inspected everything. I fired it and it gave me the trouble code P1635 which translates to 5 Volt Reference #1 Circuit. My egrs are disconnected because I am running headers so i don't know if its the Mass airflow sensor or A/C.... any help is appreciated

Since it ran good before the fix, double check everything removed, connectors, electrical, and anything you might have mistakenly loosened. Sounds like you missed something when you put it back together.

Alright so I did the ole hammer trick and tapped on the alternator near the connection and it's been working fine now. Car is perfect minus needing to work on the oil pressure sending unit.
