recently picked up a 98 civic DX 5 speed 2 door coupe with 176k miles.
car had a few issues when I bought it two weeks ago but I'm just about squared away and ready for a baseline tank of fuel. I had fixed an exhaust leak and both 02 sensors were lazy, causing a p0170/p0171 CEL. I just installed an UltraGauge and love it! best $60 yet. I was able to scan and diagnose the lazy 02's using the UG features.
with the CEL on and car running pig rich I achieved an average of 34 mpg driving the speed limit, no hyper milling. next tank should be significantly better now that the engine is running efficiently.
here's the car as I bought it 11/12:
full grill block for the winter; just finished tonight:
temporary warm air intake:
going to make a sheet metal box around the header and put the air inlet in or close to the box to keep intake temps up. at idle I'm around 92 degrees, at speed it drops to 64-68 degrees.
that's it for now
