Used 2000 Civic SI for sale in BEAUFORT, SC

EM1. B16 engine. 200,000 plus on frame. Engine has new gaskets, rings bushings and seals about 10,000 miles ago. No receipt. I did work. Many new items: battery, alternator, radiator, carpet to name a few. Outside paint is to be expected for a 19 year old car that’s been a daily driver up until recently. Runs great, ac works. Transmission is smooth. Does have flaws; cracked window, passenger side window comes off track. Intermittent CEL light P0133. Changed both O2 sensors awhile back, I think it’s due to the catalytic converter and air getting bottlenecked. It did have a straight pipe there and aftermarket exhaust and headers, so I’m assuming it’s a flow issue. Doesn’t affect me driving though. Any other questions ask. I’ve tried to return this to stock since I purchased it about 6 years ago. I just can’t find an original air intake box.
