i JUST got a crx yesterday with a b16a in it. The whole fuel system has been upgraded, minus the fuel pump (stock dx) it also has a s1 tranny (SUPER short gears) and a ROUGH rich tune on the car. The a/f gauge on the car when i first got it said it was running rich like the guy said, well i drove it all the way home (80mph 5k revs, for 2 hours) note* it would act like it was dieing running LEAN after 45 mins of driving then jump back up and run rich after a couple sec and be fine for another 20-30 mins. Well any time i run the car now it says its running LEANNN and throwing a check engine light. Im positive its the fuel pump but im just checking. THANK YOU ALL.

First check what the code is then move on from there.

After that I would probably datalog it with a wideband before doing anything else.

I'm assuming the A/F gauge is just a gauge running off your narrowband o2 sensor?
