I'm on the way back from Kentucky having picked up my new JDM Shortblock.
About an hour into the return trip I made a 1hr stop for lunch.
Upon starting the car back up I immediately got a P0174 (System Too Lean Bank 2).
I have never seen this code before and I just finished driving 1000 miles with no issues.
I reset the code and hit the road. about an hour later I noticed some hesitation on light acceleration and what seemed like a misfire when lifting off the pedal. The CEL then came on again.
I pulled over at the next exit and put more gas since I only had 1/4 tank left.
I reset the code and got back on the road.
It drove fine for about 10 minutes then the same symptoms reoccurred.
Since this car has gone through a bunch of alternators in the past I took a chance and swapped the alternator that I brought along as a backup.
Same thing 10 minutes then the car feels like its missing again.
To make a long story short I drove it all the way back to Summit Racing near Akron. The fuel economy went from 19.5 mpg cruising at 80mph down to 15 MPG.
When looking at the exhaust it looks pig rich.
Since we were already at Summit Racing I grabbed 2 front O2 Sensors since I suspect that the car has a bad one.
Is there anything else that I may have missed?
