A bit of history...I bought my '92 VX in April with 139k. All stock and clean. I wanted a federal version, so I bought one in Colorado and had it shipped to California. Right off the bat, it didn't pass smog. High HCs. The car also had the hesitation symptom that seems to be so common amongst VXs. I don't have a lot of spare time to work on cars, so getting my VX to run right was left as a low priority, slow project. Over the last 4 months, I changed the plugs and wires (NGK), installed a new 5 wire O2 sensor and catalytic converter. Turns out the ignition timing wasn't set correctly when the PO replaced the distributor. It was ridiculously retarded at like ~5 deg. BTDC.
So I set the timing to factory specs, and the car runs soooo much smoother.
I was averaging 33mpg before this adjustment, and I just filled up after running through my first full tank after the timing adjustment. I got 46mpg!
The surprising part? The tires are 185/70/13 and were at 28psi all around. I bumped them up to 43psi all around yesterday. I can't wait to see what kind of mileage I'll see at the end of this tank
Oh, and now my car feels like it has power steering!
