Cel gone, now fuel leak...

Driving down the highway yesterday, and I got a Cel.
Checked for codes today and got...

PO171 Bank 1 system too lean
P1201 Cylinder 1 random misfire
P1202 Cylinder 2 random misfire
P1203 Cylinder 3 random misfire

Stock 1995, 98,000 miles... hadnt owned it a full week yet so I'm a little pissed to say the least. If anyone has any solutions or info before I get in touch with an nsx tech let me know... thanks.

No need to be pissed, older cars need repair now and then. Do a search on your code #'s. You'll find a lot of experience troubleshooting these cars here. Probably an 02 sensor :wink:. Easy to diagnose really. Just unplug the 02 sensor and if it runs OK, there's your problem. Good Luck!

I recently had a p0171 and my nsx guru told me not to worry ,put some techron fuel injecter cleaner in the tank and errase the code.It has not come back.Your other codes could be O2 related but could also be some chronic water damage to your coilpack,a common problem.

So a couple days after my post about the cel/misfires, the code disappeared. A day later, I started to smell I bit of fuel in the cabin, removed my injectors today and found this...

I quickly got Rc on the phone and sent them off for new o rings and a cleaning. Should have them back soon, hopefully my car will be running good after reinstall.

RC does great work and you will feel a difference after they blueprint your injectors. Worked for me with these same codes.

You're lucky! I have read horror stories of engine fires here. After reading one such story, I sent my injectors to RC. I noticed a difference in starting, idling and running.
