Hello all,
I recently finished my custom front axle on my 1990 MJ, and she's not happy she sat for a few weeks. She's running a little rich, mileage first decreased from 18 to 15, and stayed at 15 for a long time. After the axle swap, she's down to 11-12, and smells rich. All my sensors are new and I JUST passed smog right before the swap, so I'm a little confused. However, it does feel slow and I've needed to reindex the distributor because I haven't done it yet, however I wanted to make certain of a few things:
1. I have a high altitude CPS, which should improve my MPG, but when I put it in, it actually went down. I noticed no performance increase. Is it because of a shitty CPS?
2. Can I index the distributor with the high altitude CPS, or should I order a stock one and use that?
