So I went for a drive today. The car was running absolutely beautifully. Then when I left a restaurant to head home, I noticed the car was stumbling bad, like the engine had a miss in it pretty badly. It was in all gears (auto trans) and drives. Drove with speeds up to 55mph, and the engine was missing the whole way home. Got it home, did the fuel pressure checks - all came out well. Looked at the plugs; they all were uniform with white/tan porcelain and clean electrodes.
Then I got to the compression test:
Cylinder 1: 105/115/120 (did it 3x)
Cylinder 2: 130
Cylinder 3: 130
Cylinder 4: 140
Cylinder 5: 130
Cylinder 6: 140
Obviously, the one I'm eyeballing is #1 ... and with x > 10% difference, I am not pleased.
So tell me, how bad is it? What do you all think? What are your thoughts after seeing those numbers (outside of the first word that came to my mind: DOOM).
NOTE: It just occurred to me, I did NOT have the throttle fully opened while doing this. I may need to re-do the tests tomorrow to make 100% sure.
